Kayaking In Wyoming: Complete Guide for Paddlers (2025)

By: Dave Samuel

Updated On: August 3, 2025

Last summer, I paddled through a section of the Green River where the canyon walls rose 500 feet on either side, and the only sounds were my paddle strokes and the occasional cry of a golden eagle overhead. That's when I realized Wyoming had completely transformed my idea of what kayaking could be. From the geothermal wonders of Yellowstone Lake to the whitewater thrills of the Snake River Canyon, Wyoming offers some of the most diverse and spectacular paddling opportunities in the American West.

After spending the past five years exploring every major waterway from Cheyenne to Yellowstone, I've discovered that the Equality State holds paddling secrets that most kayakers never find. Sure, everyone knows about Jackson Hole and the national parks, but what about the hidden canyons near Casper or the pristine alpine lakes outside Laramie? This guide covers not just the famous spots, but the local favorites that make Wyoming a true paddler's paradise.

Quick Wyoming Kayaking Overview

Wyoming's kayaking scene spans from peaceful flatwater lakes perfect for beginners to Class V rapids that'll test expert paddlers. The state's high elevation means cooler water temperatures year-round – I learned this the hard way when I dumped my kayak in Jenny Lake without a wetsuit in July. With over 3,000 miles of rivers and streams plus 10,000 acres of lakes and reservoirs, you'll find everything from multi-day wilderness expeditions to quick afternoon paddles near major cities.

The beauty of kayaking Wyoming waters is the variety. One day you're dodging geysers in Yellowstone, the next you're navigating whitewater in Wind River Canyon. And unlike more crowded destinations, you'll often have entire stretches of water to yourself – especially if you venture beyond the national parks.

Essential Wyoming Kayaking Regulations

Before we dive into the best spots, let's cover the legal stuff. Wyoming's regulations are pretty straightforward, but I've seen too many paddlers get hassled for simple oversights. Understanding kayak registration in the USA rules specific to Wyoming will save you headaches at the launch.

Key Wyoming Kayaking Laws:

PFDs Required: Every person must have a USCG-approved life jacket. Kids under 13 must wear theirs at all times – no exceptions
Registration: Good news – non-motorized kayaks don't need registration in Wyoming
AIS Decal: This one catches people – you need an Aquatic Invasive Species decal ($5 for residents, $15 for non-residents) for any watercraft
BUI Laws: Blood alcohol of 0.08% or higher will land you in trouble
Lighting: Kayaking after dark requires a white light visible from all directions

I always keep my AIS decal receipt in my kayak's dry storage – rangers check these regularly at popular launches.

Major Kayaking Regions in Wyoming

1. Jackson Hole & Grand Teton National Park

Jackson Lake - The Crown Jewel

Jackson Lake isn't just big – it's 15 miles of pristine paddling with the Teton Range as your backdrop. I launched from Colter Bay Marina on a glass-calm morning last June and felt like I was paddling through a postcard. The lake sits at 6,772 feet elevation, which means even in summer, the water stays cold enough to take your breath away.

What Makes It Special: The combination of accessibility and wilderness. You can rent kayaks right at the marina, but paddle 30 minutes north and you'll find hidden coves where moose wade in the shallows. I've spotted everything from bald eagles to black bears from my kayak here.

Best Routes:

Colter Bay to Half Moon Bay (4 miles round trip, beginner-friendly)
Signal Mountain boat launch to Elk Island (6 miles, intermediate due to afternoon winds)
Full lake traverse (15 miles, advanced due to distance and weather exposure)

Essential Gear: The afternoon winds on Jackson Lake can turn calm water into 2-foot chop faster than you'd believe. I always pack my best kayak helmet when conditions look iffy.

String Lake & Leigh Lake Circuit

This might be Wyoming's most Instagram-famous paddle, and for good reason. String Lake connects to Leigh Lake via a short, shallow channel that sometimes requires dragging your kayak. The payoff? Crystal-clear water with views of Mount Moran that'll make you forget the portage hassle.

The String Lake launch gets packed by 9 AM in summer. I've learned to arrive at sunrise or after 4 PM for parking. The complete circuit covers about 5 miles, perfect for a half-day trip. Pro tip: Pack lunch and claim one of the sandy beaches on Leigh Lake's north shore before the hiking crowds arrive.

Snake River - From Serenity to Chaos

The Snake River through Jackson Hole offers two completely different experiences. Above Jackson Lake Dam, you'll find 5 miles of gentle current perfect for wildlife viewing. I've floated this section dozens of times and never failed to see eagles, osprey, and usually elk or moose along the banks.

Below town, the Snake River Canyon delivers legitimate whitewater. The 8-mile stretch from West Table Boat Ramp to Sheep Gulch includes Class II-III rapids with names like Lunch Counter and Big Kahuna. This isn't for beginners – I've seen plenty of experienced whitewater kayakers swim here.

2. Yellowstone National Park Waters

Yellowstone Lake - Paddling Among Geysers

At 136 square miles, Yellowstone Lake is the largest high-elevation lake in North America. But size isn't what makes it special – it's the geothermal features you can only see from the water. Paddling past the West Thumb Geyser Basin, you'll spot underwater hot springs creating patches of impossibly blue water.

Critical Safety Note: The lake's average summer temperature is 60°F, but it can drop to 40°F in spring and fall. Hypothermia is a real risk. I never paddle here without a wetsuit, even in August. Check out proper kayaking safety rules before attempting Yellowstone Lake.

Best Launch Points:

Grant Village for West Thumb exploration
Bridge Bay Marina for backcountry access
Sedge Bay for quieter paddling

Wind is the biggest hazard here. The lake can go from mirror-calm to 4-foot waves in 20 minutes. I've been windbound on beaches multiple times, which is why I always pack extra food and emergency gear.

Lewis Lake & Shoshone Lake

These backcountry gems see a fraction of Yellowstone Lake's traffic. Lewis Lake connects to Shoshone Lake via a 3-mile channel that requires dragging your kayak through shallow sections. The effort pays off – Shoshone Lake offers complete solitude and some of the park's best backcountry campsites (permit required).

Last September, I spent three days paddling this circuit. The wildlife was incredible – a grizzly fishing along the shore, sandhill cranes in the marshes, and more waterfowl than I could identify. Just remember: this is serious wilderness paddling. Bring bear spray, know how to secure your kayak, and file a float plan.

3. The Green River System - Wyoming's Hidden Gem

Green River Lakes to Fontenelle Reservoir

This multi-day expedition ranks among Wyoming's best-kept paddling secrets. Starting at Green River Lakes in the Wind River Range, you'll paddle through some of the most scenic and remote country in the lower 48. The full trip to Fontenelle Reservoir covers about 90 miles and takes 4-6 days.

I attempted this trip two years ago with a buddy in late July. The upper section requires hiking your kayak about a mile from the parking area to the put-in. From there, it's mostly Class I water with occasional Class II rapids. The real challenge is the remoteness – once you're in, there's no easy bail-out for 50+ miles.

Multi-Day Logistics:

Camping is mostly on BLM and Forest Service land (no permits needed)
Water resupply is limited – bring a good filter
The New Fork confluence adds significant flow
Take-out at Fontenelle requires a long shuttle

Green River Whitewater Park - Urban Paddling

Not all Wyoming kayaking requires wilderness commitment. The City of Green River created an artificial whitewater park on Expedition Island that's perfect for afternoon practice sessions. The main feature, Castle Falls, provides a legitimate Class III drop with nice eddies for working on skills.

I've spent many evenings here when passing through on I-80. The park has two channels – one for tubing families and another for kayakers. It's free, open year-round (if not frozen), and has changing facilities. Just don't expect world-class whitewater – think of it as a fun playground rather than serious rapids.

Seedskadee National Wildlife Refuge

Downstream from Fontenelle Dam, Seedskadee offers completely different paddling. This 37-mile stretch meanders through high desert, creating wetland habitat for hundreds of bird species. I've seen more wildlife here than anywhere else in Wyoming – moose, river otters, beavers, and during migration, thousands of waterfowl.

The current is gentle, perfect for beginner kayakers or anyone wanting a relaxing float. Multiple access points let you customize trip length from 3 to 45 miles. Just check dam release schedules – high water can make some sections challenging.

4. Wind River Canyon & Bighorn Basin

Wind River Canyon - Exclusive Access

Here's something unique: the only way to kayak Wind River Canyon is through Wind River Canyon Whitewater & Fly Fishing, a Native American-owned company with exclusive access to this tribal land. The restriction means you'll share the river with maybe one other group instead of dozens.

The canyon walls rise 2,500 feet above the river, creating a corridor through time – you'll paddle past rock layers spanning 600 million years. The rapids range from Class II to IV depending on flows. When I ran it last spring at high water, the waves in Upset Rapid were bigger than anything I'd seen in Wyoming.

Bighorn Lake & Canyon

Straddling the Wyoming-Montana border, Bighorn Lake offers 71 miles of flatwater paddling through spectacular canyon scenery. The lack of current makes it ideal for sea kayaking techniques and multi-day trips. I've paddled the southern section from Horseshoe Bend Marina multiple times, always discovering new side canyons to explore.

The wind can be fierce here, funneling through the canyon. Plan early morning paddles and be prepared to wait out afternoon gusts. Wildlife includes bighorn sheep (naturally), black bears, and if you're lucky, wild horses on the canyon rim.

5. Fremont Canyon - Central Wyoming's Wonder

Fremont Canyon might be Wyoming's most underrated paddle. Located between Pathfinder and Alcova Reservoirs near Casper, this flooded canyon offers dramatic scenery just 40 miles from town. The 500-foot walls create a sense of isolation despite the easy access.

The standard trip starts with a boat ride from Alcova Resort, which drops you with kayaks at the canyon entrance. You then have 2-3 hours to paddle back at your own pace. When I did this in May, the water temperature was a shocking 47°F – proper kayak safety gear is essential.

What to Expect:

Generally calm water, but dam releases can create current
Limited landing spots due to sheer walls
Exceptional geology and occasional wildlife
Popular with motorboats on summer weekends

6. Laramie Area Lakes - High Plains Paddling

Medicine Bow Mountains Lakes

The Snowy Range west of Laramie holds over 100 alpine lakes, many accessible for paddling. Mirror Lake and Lake Marie sit right off Highway 130, offering spectacular high-altitude kayaking without the hiking. At 10,000+ feet elevation, these lakes stay ice-free only from July through September.

I learned about kayak weight considerations the hard way trying to haul my touring kayak up to Brooklyn Lake. Now I use an inflatable for these mountain adventures. The paddling is serene – no motorboats allowed – with views of Medicine Bow Peak reflecting in crystal-clear water.

Curt Gowdy State Park

Just 24 miles west of Cheyenne, Curt Gowdy offers three reservoirs totaling 400 acres of paddling. It's perfect for kayaking near Cheyenne Wyoming when you can't commit to a longer drive. Granite Reservoir is the largest and allows motorboats, while Crystal and North Crow stay quieter.

The park sees heavy weekend use, but weekday mornings offer solitude. I often combine paddling here with mountain biking on the excellent trail system. The varied terrain – meadows, granite formations, and pine forests – makes every paddle visually interesting.

7. North Platte River System

Upper North Platte

From its source in Colorado, the North Platte enters Wyoming as a premier fly-fishing river that also offers excellent kayaking. The stretch from Routt access to Saratoga provides 50 miles of mostly Class I-II water with stunning mountain scenery. Several outfitters in Saratoga offer guided trips and shuttles.

I float this section every autumn when the cottonwoods turn gold. The river braids through wide valleys with the Snowy Range as a constant backdrop. Wildlife is abundant – I've seen everything from golden eagles to the occasional moose. Just watch for shallow spots during low water years.

Alcova & Pathfinder Reservoirs

These massive reservoirs on the North Platte offer different experiences than Wyoming's mountain lakes. Alcova is more developed with marinas and camping, while Pathfinder feels wonderfully remote despite good road access. Both can get seriously windy – I've been stuck on beaches waiting for safe conditions more than once.

What sets these apart is the fishing. Using proper kayak modifications for angling, I've caught trophy-sized trout and walleye. The rocky shorelines and hidden coves provide endless exploration opportunities. Just respect the weather – these big waters demand caution.

Seasonal Considerations for Wyoming Kayaking

Spring (April-May)

Spring paddling in Wyoming means snowmelt, high water, and cold temperatures. Rivers run fast and murky, making them challenging even for experienced paddlers. I stick to lakes during spring, always wearing a drysuit. The upside? You'll have popular spots entirely to yourself.

Summer (June-August)

Peak season brings crowds to national parks but perfect conditions statewide. Water levels stabilize, temperatures become (somewhat) comfortable, and long days allow ambitious trips. I've learned to start early – not just for parking, but because afternoon thunderstorms and wind are common above 7,000 feet.

Book accommodations and guided trips well in advance. Consider kayaking apps for weather monitoring and navigation, especially in remote areas where cell service is spotty.

Fall (September-October)

My favorite season for Wyoming paddling. Crowds disappear, aspens turn gold, and elk bugling echoes across the water. Water temperatures drop quickly though – what's comfortable in early September can be dangerously cold by October. I always pack extra insulation and monitor weather obsessively.

Winter Opportunities

Believe it or not, some Wyoming waters stay open year-round. The Firehole River in Yellowstone, warmed by geothermal features, offers surreal winter paddling. Green River below Fontenelle Dam also stays open. I've paddled both in January – the solitude is incredible, but the margin for error shrinks to zero.

Planning Multi-Day Kayaking Trips

Wyoming's remote waters make it ideal for expedition paddling. I've completed week-long trips on the Green River, Yellowstone Lake, and various reservoir systems. Here's what I've learned about kayak camping:

Route Planning:

Always have bailout options identified
File float plans with someone reliable
Check fire restrictions and camping regulations
Plan conservative daily mileage – Wyoming wind can stop you cold

Essential Gear:

Bear canisters (required in many areas)
Water filtration system with backup
Weather radio for remote areas
Extra paddle and repair kit
Maps in waterproof case (don't rely solely on GPS)

Permits and Regulations:

Yellowstone and Grand Teton require backcountry permits
Some rivers cross private land – research access rights
Wilderness areas may have group size limits
Fire permits often required outside developed campgrounds

Safety Considerations Specific to Wyoming

High Altitude Effects

Most Wyoming paddling happens above 6,000 feet. If you're coming from sea level, the altitude hits hard. I learned this during my first Jackson Lake trip – what should have been an easy 10-mile day left me exhausted. Allow extra time for acclimatization and don't push too hard the first few days.

Wildlife Encounters

Wyoming kayaking means sharing water with serious wildlife. I've had close encounters with:

Moose: Most dangerous, especially cows with calves. Give them 100+ yards
Bears: Both black and grizzly. Carry bear spray accessible from your cockpit
Bison: In Yellowstone waters. They swim surprisingly well
Rattlesnakes: At lower elevation launch sites

Learn proper sea kayak precautions even for inland paddling – many safety principles apply regardless of water type.

Weather Hazards

Wyoming weather changes fast. I've experienced snow in July, lightning from clear skies, and 60mph winds that appeared from nowhere. Always:

Check detailed forecasts, not just daily highs/lows
Understand local weather patterns
Have appropriate gear accessible
Know when to get off the water

Cold Water Year-Round

Even in peak summer, most Wyoming waters stay cold. Yellowstone Lake never gets above 60°F. Mountain lakes might hit 65°F in shallow bays. I've seen too many paddlers underestimate this – hypothermia is a real risk. Minimum safety gear includes:

Wetsuit or drysuit for early/late season
Spare clothes in dry bag
Emergency shelter/fire starting
Knowledge of cold water shock response

Hidden Gems and Local Favorites

After years of exploring, these lesser-known spots have become my favorites:

Ocean Lake (Riverton)

This prairie lake doesn't look like much on maps, but the bird life is spectacular. Local volunteers sink Christmas trees each winter to create fish habitat, making it surprisingly good for kayak fishing.

Boysen Reservoir

Often overlooked for flashier destinations, Boysen offers great paddling with a fraction of the crowds. The wind-carved badlands create a unique backdrop, and hidden coves provide excellent camping.

Big Sandy Reservoir

Way out in the Red Desert, this remote reservoir sees mostly local anglers. The sense of isolation is complete – on my last trip, I didn't see another person for three days.

Lower Laramie River

Between Woods Landing and Jelm, the Laramie River offers accessible whitewater close to town. It's where University of Wyoming students learn to paddle, creating a fun, welcoming scene on warm afternoons.

Essential Gear for Wyoming Conditions

Through trial and error (mostly error), I've refined my Wyoming kayaking kit:

Always Pack:

Wetsuit/drysuit appropriate for conditions
Sun protection at altitude is crucial
Repair kit with extra parts
First aid supplies for remote areas
Communication device (satellite messenger for backcountry)
Proper kayak size for conditions

Wyoming-Specific Items:

Bear spray in accessible spot
Extra warm layers (weather changes fast)
Water filtration (many areas lack potable water)
Detailed maps (cell coverage is spotty)
Cash for launch fees (many sites lack card readers)

Common Mistakes to Avoid

I've made all these mistakes so you don't have to:

Underestimating distances: Wyoming is huge. That "nearby" lake might be 2 hours on dirt roads
Ignoring wind forecasts: Afternoon winds can make large lakes unpaddleable
Forgetting the AIS decal: $100+ fine plus the hassle
Inadequate cold protection: "It's July" doesn't mean warm water
Poor altitude preparation: Your normal paddling pace won't work at 8,000 feet
Insufficient emergency gear: Help can be hours away

Planning Your Wyoming Kayaking Adventure

Start with these steps:

Choose your region based on driving distance and skill level
Check current conditions – water levels, weather, fire restrictions
Reserve permits/campsites early for popular areas
Plan conservative itineraries – Wyoming always takes longer than expected
Prepare for self-sufficiency – services are limited outside major areas

FAQ Section

What's the best time of year for kayaking in Wyoming?

July through September offers the warmest conditions and most stable weather. I prefer September for fewer crowds and stunning fall colors, though water temperatures drop quickly. June can work for lower elevation spots, but mountain lakes often still have ice.

Do I need special permits for kayaking in Wyoming?

You'll need an AIS decal for any watercraft ($5 residents/$15 non-residents). Backcountry camping in national parks requires permits. Some rivers cross private land requiring permission. Otherwise, most Wyoming waters are freely accessible.

What's the water temperature like in Wyoming lakes and rivers?

Cold year-round. Even in peak summer, expect 50-65°F in most waters. High altitude lakes rarely exceed 60°F. I always paddle with immersion protection – hypothermia is a real risk even in July.

Are there any beginner-friendly kayaking spots in Wyoming?

Absolutely! String Lake, Ocean Lake, and Alcova Reservoir offer calm conditions perfect for beginners. The Green River through Seedskadee is gentle with lots of wildlife. Many outfitters offer guided trips ideal for first-timers.

Can I kayak in Yellowstone and Grand Teton without a guide?

Yes, but know the regulations. Some Yellowstone waters are off-limits. Both parks require backcountry permits for overnight trips. I recommend guided trips for first-time visitors – the local knowledge is invaluable for safety and finding the best spots.

What wildlife might I encounter while kayaking in Wyoming?

Moose, bears (black and grizzly), elk, bison, deer, eagles, osprey, pelicans, and countless waterfowl. In my experience, moose pose the biggest danger – they're unpredictable and surprisingly aggressive. Always maintain safe distances and carry bear spray.

Are there any year-round kayaking opportunities in Wyoming?

A few spots stay open: Firehole River in Yellowstone (geothermally warmed), Green River below dams, and some spring-fed waters. Winter paddling requires extreme cold-weather gear and experience. I only attempt it in groups with proper safety equipment.

How challenging is kayaking at high altitude?

The altitude affects everyone differently, but expect reduced endurance your first few days. I plan shorter distances and easier routes until acclimated. Dehydration happens faster too – drink more water than you think you need.

What's the best way to transport kayaks to remote Wyoming locations?

A reliable vehicle with good clearance helps – many launches require dirt road driving. I use a pickup truck setup for easy loading/unloading. Consider inflatable kayaks for hike-in alpine lakes. Always carry spare tie-downs and padding.

Are there any Wyoming waters I should avoid as a kayaker?

Skip the Shoshone River through Buffalo Bill Reservoir spillway (deadly hydraulics). Avoid the Snake River below Alpine during peak irrigation releases. Never attempt Wind River Canyon without proper experience and the required tribal guide. When in doubt, ask locals – they know the hazards.

Final Thoughts

Wyoming transformed my understanding of kayaking. It's not just about the paddling – it's about experiencing some of America's last wild places from the intimate perspective of a kayak. Whether you're drawn to the volcanic wonders of Yellowstone, the granite spires of the Tetons, or the hidden canyons of the high plains, Wyoming delivers adventures that stay with you long after you've dried out your gear.

The key to enjoying Wyoming's waters is respect – for the weather, the wildlife, and the wild nature of these places. Come prepared, stay flexible, and always err on the side of caution. Do that, and you'll discover why those of us who paddle here can't imagine kayaking anywhere else.

See you on the water – probably somewhere with no cell service, surrounded by mountains, wondering why you waited so long to paddle Wyoming.
