Indian Flats Professional Review and Guide
"Located 30 miles northeast of Helena at the north end of the Big Belt Mountains. Spectacular limestone cliffs in Trout Creek Canyon, beautiful meadows and open forest on the climb to Indian Flats. Look for deer, elk, black bears, and cougars. This route offers access to Hogback Mountain and Indian Flats cabin, which can be rented from the Forest service (call ahead for reservations).
For an extended stay, drive foot, water, sleeping bags, and extra clothes up to Indian Flats cabin, then start the ride back in York. Spend the next day doing day rides from the cabin. On the third day, drop down to Nelson and back to York via Beaver Creek Road and County Road 4."
