Distance: 3 Miles. Amazing views of the Cathedral Spires. Explore the Noble Mica Mine. Avoids the tourist crowd at Harney Peak. Elevation Gain: 600 ft. One of the tallest features west of the Rockies.
The trail starts at the Little Devil's Tower Trailhead which is located roughly one mile east of Sylvan Lake on Highway 87. Take Trail #4 for around 1/2 mile until a fork in the trail. The right fork takes you to Harney Peak, while the left takes you to Little Devils Tower. Along the trail there are a few spur trails leading to granite overlooks. One can also explore the Noble Mica Mine which is a short walk off the trail. Around a mile into the hike, the trail goes into a rather large granite crevasse. From here, the trail is marked with painted trail markers on the granite.
The top of Little Devil's Tower offers spectacular views of Harney Peak (tallest point east of the Rockies until Europe) and the Cathedral Spires. Fall is an incredible time to hike in this area as all of the aspen trees are changing colors.
