Swim in Glenwood Hot Springs, the 'world's largest hot springs pool,' an hour from both Vail and Aspen.
Glenwood is best known for its large hot springs pool, kept between 90 and 93 degrees, while the minerals in the water are meant to provide a natural therapy to the body. There is also a smaller therapy pool, at 104 degrees, and a spa, as well. You'll find all the amenities you need here, and within reach of lots of outdoors attractions and activities.
