Great alpine lake sitting in a cirque/basin at the base of Sacajawea Peak. The main access trail is a gentle grade of switchbacks to the lake's edge for magnificent views of the pristine lake and the dramatic mountains behind. There is a rougher rooted out trail that encircles the lake, and you can take the steps back up to the trail head, which is a "shortcut". Highly recommended! There are longer trails that access the lake, too, if you want a longer hike and better workout. Campground nearby, mostly just tents, since trailers can't be hauled up the rough access road.

Fairy Lake is a high elevation lake tucked in the trees just below treeline in Custer Gallatin National Forest. There is camping close by and a trailhead for gaining access to Sacagawea Peak and Bridger Ridge. The reservoir stays frozen late into the springs and has a small nature trail that travels around the banks.
