4. Hike to a Ghost Town
While there are plenty of ghost towns all around the state of Colorado, one of the most iconic abandoned spots is the town of Crystal. Its most notable structure is the Crystal Mill. If you want to get a picture of this spot for yourself, you’ll need to trek 5.5 miles down a very bumpy dirt road. Some people will drive this with a 4×4 vehicle, though most seem to hike it.
