Cottonwood Hot Springs is about an hour-and-a-half drive southwest of Denver, Colorado. It’s a bit difficult to see all of the pools in these photos, but there are several pools varying in size and water temperature. It isn’t the most aesthetically beautiful hot spring spa, but there are quite a few amenities, such as saunas, pools, massages services, private baths, and shade (which is surprisingly scarce with most hot springs pools I’ve experienced).
