Up Hyalite Canyon, this loop follows its namesake creek, which is a tributary of Hyalite Creek. The loop takes you through dense pine, lodgepole, and aspen forests and wildflower meadows, and over the divide between the canyons into Bozeman Creek. Starting at the lower gate on Hyalite Canyon Rd., trek half a mile to a road fork (and the upper trailhead). Start the loop on the left and continue clockwise. About a mile in, pass through a gated road to the right. After 4 miles, you'll encounter a horseshoe bend; 100 yards past that is an unmarked footpath to your right. Take that trail back instead of the road. Carry bear spray.
This trail is accessible year-round, and it's a popular Nordic ski spot in the winter.
Drive south on S. 19th Rd., and turn left onto Hyalite Canyon Rd. Continue for 6 miles to an unpaved road on the left. Turn left to park by the lower gate.
