Located between Aspen and Vail, you'll find the World's Largest Hot Springs Pool. The Ute Indians called it Yampah, meaning "big medicine." Soothe your muscles after outdoor activities year round. The large pool is kept at a comfortable 90°- 93° F and the smaller therapy pool averages about 104° F. Additional amenities include a lodge, spa, athletic club, grill and shopping. Relieve muscle and joint pain, or just relax and feel the wonder of a soak in our hot springs. Soaking in hot, highly concentrated mineral water has many health benefits. Increasing body temperature helps the body naturally kill harmful germs and viruses, eliminate toxins, and increase blood flow. The essential minerals gives the body a natural boost. You will feel the difference within minutes of stepping in. Jump in the large pool, at over 400 feet long, and "cool down." Swim laps or practice your form on the diving board. Bring your own cooler and snacks, or stop by the poolside Grill to grab a bite.

It's always a good day for a soak in the clear warm waters of the Ouray Hot Springs Pool! The hot springs of Ouray have been enjoyed since at least the 14th century when native Ute Indians used the naturally hot clear water for healing. Settlers came to the area in the late 1800's in search of gold and precious minerals, and many found comfort in the natural hot springs. The current swimming pool was constructed in the 1920's and has been a favorite destination ever since. Seven different springs supply the pool with water. At the source some of this water is 150 degrees! The pool consists of several sections maintained at different temperatures for different tastes. The hot section is approximately 104 degrees, and a soaking section, perfect for families and prolonged soaking, is typically 95 degrees, or so. The lap lanes and deep section are usually about 80 degrees in the summer and fall, and cooler than that in the winter months when there is snow on the ground. The Ouray Hot Springs Swimming Pool is an outdoor pool open all year. Many people enjoy the pool the most in the winter, after a day spent ice climbing, cross country skiing, snowshoeing, skating on the local ice rink (skates are available to rent at the Hot Springs Pool), or simply as a place to relax and enjoy the splendid scenery of the San Juan Mountains.

Old Town Hot Springs is an historic all-natural hot spring and recreational facility in the heart of downtown Steamboat Springs. It is family friendly and has been the place for recreation and rejuvenation for visitors and locals alike for over 100 years. The swimming and soaking pools served as a gathering and bathing place for the Ute Indians who first settled in the area. Then in the late 1800s, it was a social spot and a bathing place for the early homesteaders. Old Town Hot Springs sits at an elevation of 6,700 feet and offers eight pools, including two 230-foot waterslides, a 3,000 square foot hot activity pool, an aquatic rock climbing wall, the historic Heart Spring pool, eight lap lanes, and massage.
