Top 18 Swimming Spots in Colorado for Summer Fun

1. Colorado Historic Hot Springs Loop

Colorado’s mountains harbor a secret: natural, thermal hot springs that occasionally bubble to the surface and form mineral-rich pools. The state boasts dozens of hot springs of various kinds, from large, formal swimming pools to tiny, hidden, outdoor ponds.

Can’t decide which to visit? Go hot springs hopping. One popular pathway is the Colorado Historic Hot Springs Loop, which takes you on a 720-mile journey between 19 different hot springs.

Along the way, you’ll experience vapor caves and aquatic centers. You can swim in the popular outdoor Strawberry Hot Springs in the forest of Steamboat Springs (where you can swim nude after dark). Additionally, visit Iron Mountain Hot Springs, home to the world’s largest mineral hot springs pool, which features underwater jet chairs in Glenwood Springs.

You’ll also find Pagosa Springs, known for the world’s deepest hot springs (at least 1,002 feet). While swimming in this extremely hot pool is prohibited for safety, Pagosa has numerous other pools to choose from, including the extra hot Lobster Pot.

2. Grand Lake

Grand Lake is Colorado’s biggest and deepest natural lake, located in the town bearing its name. Surrounded by tall trees and rolling hills, Grand Lake is impressive to look at and even more exciting to boat on.

Additionally, it features a great swim beach with a sandy area just a short walk from the boardwalk and a historic downtown lined with more than 60 stores and restaurants. Rent stand-up paddleboards, canoes, or try fishing for alternative experiences at Grand Lake.

3. Zappatta Falls

Experience a hidden waterfall in southern Colorado at Zappata Falls. This enchanting spot is one of the best places to cool off in San Luis Valley; however, ensure you visit when the run-off isn’t too strong for safety.

Zappata Falls is conveniently located near Great Sand Dunes National Park at the top of a winding road. Along the route, you might think you’ve taken a wrong turn, but keep going. The breathtaking parking lot view will soon lead you to a private, 25-foot waterfall tucked away in a rocky valley. Accessing it requires wading through the tree-shrouded Rio Grande River, one of the longest rivers in the nation.

Even if the water is too swift to swim in, the view is still stunning. If timed well during the warmer summer months with temperatures soaring around 100 degrees, a splash under the waterfall becomes the perfect way to cool down, Colorado style.

4. Conundrum Hot Springs

Conundrum Hot Springs is a remarkable destination, particularly due to its status as one of the world’s highest hot springs, sitting at 11,200 feet above sea level, not far from Aspen.

Reaching the hot springs requires an adventurous 9-mile hike along the Conundrum Creek Trail. Yet, the effort is worthwhile. Clothing is optional, and the pools are completely surrounded by nature. Luckily, the water is naturally heated, providing a warm escape from the often frigid temperatures experienced in other mountain water bodies, even in summer.

Consider bringing a tent to camp nearby; it can be quite the challenge to complete the long hike back after unwinding in the soothing waters.

5. Devil’s Punchbowl(s)

Colorado hosts two bodies of water known as the Devil’s Punchbowl, and both are worth visiting for similar thrilling experiences.

The first Devil’s Punchbowl is located near Aspen and the Grottos on Independence Pass. This spot is ideal for thrill-seekers. Here, waterfalls spill into a stunning watering hole embraced by towering 20-foot cliffs. Brave (or adventurous, depending on your perspective) swimmers can go cliff-jumping here. It’s best to visit later in the summer when the water levels are lower, and the Roaring Fork River isn’t as turbulent.

The second Devil’s Punchbowl is nearer to Marble and Crested Butte, also close to a mountain pass (Schofield Pass). Similar to Aspen’s punchbowl, this pool is also fed by a waterfall, allowing for cliff-jumping as well (at your own risk). Be aware that the hike can be challenging, the water is cold, and jumping may be hazardous, yet it remains a popular spot.

6. Yampah Vapor Caves

A dip in the water can be relaxing, too. Head to Glenwood Springs for the Yampah Vapor Caves, a natural, underground, steaming rock cave that has been transformed into a full-service day spa. Float in the mineral-rich, hot springs water while enjoying spa treatments, such as mud baths, massages, reflexology, and body wraps. Additionally, indulge in steam treatments within the cave and relax on marble benches hidden in the dark alcoves.

7. More Places to Swim

Medano Creek flows through the stunning Great Sand Dunes National Park. While you cannot exactly swim here as the water often runs as more of a trickle, it serves as a unique oasis for sandcastle building and splashing under the warm sun by the shadow of the towering dunes.

8. Water World

Water World, located in Federal Heights (the Denver area), is Colorado’s most popular water park. It claims to be America’s biggest water park.

This 64-acre aquatic amusement park features slides, lazy rivers, gondolas, wave pools, and an array of creative water adventures. With a total of 49 rides and slides, there are attractions suitable for individuals of all ages and thrill-seeking levels. Rent a cabana or party shack for an unforgettable day.

9. Mystic Island Lake

If you love alpine lakes, take a trip to Mystic Island Lake near Eagle, not far from Vail. Base your stay at the Fulford Cave Campground, which allows easy access to trails leading to this stunning alpine lake, perched at 11,400 feet above sea level. There’s something enchanting about a lake in the clouds, though it may be too chilly to dip a toe in.

10. Chatfield State Park

If you’re seeking a water adventure close to Denver while still feeling immersed in nature, Chatfield State Park in Littleton is an ideal choice. Engage in swimming, waterskiing, boating, and fishing in this popular lake, conveniently located not far from the city center. You can even camp here, making it a perfect getaway that retains the comforts of urban life.

11. Lost Man Lake

If you’re visiting Aspen and seeking an aquatic adventure, then Lost Man Lake, located near Independence Pass (by Aspen), is perfect for you. You’ll need to hike Lost Man Pass to reach this gem.

On the other side of the mountain, you’ll find this small lake, set at an elevation of 12,450 feet, providing polar plunge opportunities.

Grab a tube and float down the creek for an exciting adventure through the trees and the town. Afterward, enjoy a leisurely stroll along the water. One of the quirkiest annual events here is Tube to Work Day, somewhat akin to Bike to Work Day but splashier. Essentially, people rent tubes and float down the creek to their workplaces, making it a festive occasion likened to a city party.

Blue Mesa Reservoir, located in Curecanti National Recreation Area, extends near Montrose and Gunnison. This is Colorado’s largest body of water (20 miles long), offering numerous beaches (albeit rocky), exceptional swimming, great fishing, and breathtaking views. Consider scuba diving here as well. This destination is undoubtedly a bucket-list item for Colorado, as its size is surprising in this landlocked, mountain-heavy state.
