Great nontechnical hike to the summit of one of Bozeman's iconic southern peaks. A few stream crossings for filtration if you want to go light. Some steeper grades just up from the lake, but mostly very manageable grades, gorgeous views! Mountain goats were seen as well. Highly recommended.

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.

Easy well-maintained hike to the falls from the parking lot. If you want a little more interesting of a hike, make sure you don't miss the "connector", which adds some more climbing and descending, but it takes you closer to the Gallatin River, and there is another beautiful small stream that you cross along the way. Built up. nicely with boardwalks that would be fun on a mountain bike.

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.

The singular cabin at Mystic Lake is reservable year round and can only be accessed via foot, bike, or horse. The lake is open for recreational uses, but no motorized vehicles are allowed on the waters. If you want to check out the cabin as you're passing by, be aware that there might be people with reservations staying there already.
