The top 6 beaches and swimming destinations in Wyoming

When you think of Wyoming, you might picture snow-capped mountains, classic cowboy towns, and wandering bison, but this landlocked state also features a variety of lakes, rivers, and beaches perfect for swimming, soaking, and even surfing.

With summer being brief and delightful, locals fully embrace the warm weather by making the most of their time on the water. Remember to respect wildlife, bring your sense of adventure, and enjoy the breathtaking views—even if the water is a bit chilly. Here are the premier swimming spots in Wyoming.

String Lake offers tranquility, clarity, and stunning views of the snow-covered Tetons

While Grand Teton National Park is famed for its wildlife and breathtaking hikes rather than warm waters (as rivers and lakes are fed by melting snow and glacial runoff), the pristine waters of String Lake defy this norm. Shallow enough for family fun, it warms up more than the nearby Jackson or Jenny Lakes. You’ll spot plenty of canoes, kayaks, and paddleboards—available for rent at Dornan’s—as the lake remains relatively calm even on breezy days, with no motorboats permitted. The picturesque Teton range serves as a stunning backdrop for the lake's small beaches and picnic spots, perfect for a day of relaxation. Just be sure to adhere to the park’s food storage regulations, as this is bear territory.

Alcova Reservoir features a designated swimming beach for kids

At the popular summer getaway of Alcova Reservoir, there are four beaches to enjoy, all offering great swimming access. The Children's Swim Beach is particularly beloved by young children for its sandy bottom and gentle waters. With beach volleyball nets, a playground, and various camping, picnic, and RV sites, the reservoir is a fantastic family-friendly spot. While the swimming areas are in sheltered coves, the lake is also perfect for boating, with eight accessible boat ramps. The best way to experience Alcova is to spend a night or two, renting a boat, bike, paddleboard, or kayak from the marina, and treating yourself to ice cream at the end of the day.

Firehole River Canyon boasts Yellowstone’s premier swimming spot

Despite its name, the Firehole River isn’t as hot as you might think, making it an ideal place to cool off after a long day of driving and exploring Yellowstone National Park. Here, you’ll find an easily accessible swimming hole away from the river’s main current—life jackets are advisable for children, and water shoes can be useful for traversing the rocky riverbed. There are also restrooms conveniently located across the street for easy changing. If swimming isn’t your thing, there’s a lovely beach where you can relax and watch the fun unfold.

Discover local history at dog-friendly Lower Slide Lake

If you’re exploring the Yellowstone and Grand Teton National Park regions, you’re likely aware that park regulations restrict where dogs can roam. The Bridger-Teton National Forest’s Lower Slide Lake is a great option for letting your pets enjoy the water as well. The reddish shoals surrounding the hills offer a unique landscape that's quite different from the more renowned parks. The lake is calm and sheltered, perfect for small watercraft like kayaks and paddleboards. Don’t forget to swing by the Kelly Deli on your way out for massive sandwiches and boozy seltzers on tap. Fun fact: this lake was formed by a notorious rockslide that dammed the river and obliterated the town of Kelly, creating both Upper and Lower Slide Lakes. You can even spot tree tops still emerging from the water at the lake's far end!

Granite Hot Springs is your go-to destination when the weather turns cold

In the northwestern corner of Wyoming, snow can fall throughout the year! Even during the warmest months of July and August, temperatures can drop significantly in the evenings, making Granite Hot Springs an excellent choice for swimming when the weather isn’t ideal. Natural hot springs flow into a man-made pool with entry fees of $12 for adults and $7 for kids. In summer, enjoy a scenic, winding drive to the springs, while winter access is limited to snowmobiles, snow bikes, or snowshoes (check for seasonal closures). Admission includes access to restrooms and changing facilities, but bring your own snacks as amenities are minimal.

You can find boat rentals and surf lessons through Teton Surf Co, and Melvin Brewing is the ideal spot to enjoy a locally brewed beer while watching the sunset over the Snake River Mountains. Evenings are filled with fellow boaters and surf lovers grilling hot dogs and soaking up the lake life.
