While it may not be as impressive as Mt. St. Helens or the Yellowstone Caldera, the Dotsero Crater is still worth checking out. A large, deep crater in the hills is not something you come across everyday on the Western slope of Colorado. With it’s ease of access, and vast network of trails, the Dotsero Crater makes for a fun side-trip, or destination campsite with great views of the surrounding mountains.
