Great article on Colorado National Monument
Lots of road cycling possibilities here and quite beautiful.
If you prefer mountain biking, the Fruita area close by is the epicenter of some great trails and you can set up camp at
Highline Lake State Park
Beautiful towering shade trees and very nice grassy camp sites.
There is even a trail in the park.
Make a reservation is you want to camp there on a weekend.
Kinda fun to dream about summer destinations during the winter time.
