Taylor Park, Co is one of the most beautiful areas, IMO. There are hundreds of miles of trails. There are Cabins for rent or RV spots across the street from a GREAT lake for fishing. Tons of rivers to fish too. From this area you can get to Aspen, Crested Butte, and Gunnison. You can't ride in the town but they are some great over looks. Lot's of old mining/ghost towns to ride to.
This is a link to the cabins, gas and food is available onsite
