Burlington Northern Hill City Trailhead to Mountain Trailhead
Milepost 49.6 to milepost 60.1 or vice versa.
The Burlington Northern Hill City Trailhead starts at MM 60.1 in Hill City and goes to MM 49.6 at the Mountain Trailhead just south of Crazy Horse Monument. It goes pretty much uphill the whole way until you hit Crazy Horse and then it goes down the last 3/4 of a mile until it hits the next trailhead. We did this 10.5 mile trailhead starting at Hill City and then turning around. The 2 miles going up to Crazy Horse are the worst since it is at a steeper slope and you can be exposed to the sun at certain times of the day. Once you turn around at the Mountain Trailhead and get back to Crazy Horse, you pretty much glide back down to Hill City making it the best part of the trip.
