Mountain Biking Curly Lake Highline

****   Add a review
#85 of 265 mountain bike trails in Montana
#6,564 in the world

This is a huge ride with a total of 5K feet of climbing over its 25 miles. The first five are on the road heading south then it forks -- veer right on 107. Stay right as the road gets rougher and steeper. At 7.2 miles take the Curly Lake trail 7159 to the right. At 10.3 miles is Curly Lake. The Curly Creek Trail 7151 plummets back to the road if you need to bail. Otherwise, continue on what will be a very strenuous climb on 7159. The high point is at about 13.5 miles and the trail disappears in the tundra, but there are cairns. Continue to follow trail 7159, passing a few more bailiouts, to mile 20.6 and turn right on the Rock Creek Trail 7089 and plummet back down to your starting point.

Getting there
From I 90 exit 256 East of Whitehall, travel south on 359. After about 6(?) miles, go right (south) on South Boulder Road. This will take you all the way to the trailhead. The first few miles are paved, but the road is narrow with sharp turns obscured by trees. About 9 miles from the turn, there will be a pullout at the exit of the Rock Creek trail on the right.
