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.

The Reas Pass lies essentially on the Idaho-Montana border, but modern maps show that the summit lies entirely in Idaho, because the Divide and the state line do not quite coincide here. The pass is also somewhat unusual in that, despite being the lowest crossing of the Divide in the vicinity, it has evidently never been traversed by a highway of any significance.

Lionhead is a 2,904-metre (9,528 ft) summit on the Continental Divide Trail. The trail that leads up and down from it is popular with mountain bikers so respect all users when hiking. It can be accessed from the Targhee Pass Highway. The peak is named because, from certain angles, it looks like the head of a lion.

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.
