Wow – what a view! Garnet Mountain Fire Lookout sits on the apex of Garnet Mountain south of Bozeman, Montana. It is the only fire lookout for rent on the Gallatin National Forest and offers outstanding views of the surrounding mountain landscape.

Travel 18 miles south of Bozeman on Highway 191 until you reach Storm Castle Creek Road #132 (formerly known as Squaw Creek). Turn left. After you cross the bridge turn right at the T-intersection. Do not turn off the main road as you pass the helibase. Access is by foot, atv, ski, snowshoe, or snowmobile. Two trails access the lookout:

Summer Shortcut

  • The trailhead for the 3 1/2 mile Garnet Mountain Lookout Trail #85 is approximately 1 1/2 miles up the Storm Castle Creek Road.
  • Park in the parking lot on the left side of the road.
  • Take the trail south and cross Storm Castle Creek at the bridge. Due to avalanche hazards this trail is not recommended during winter months.
