Parking for Middle Cottonwood trail. Road gets very icy in winter, drive with care.

Not the “full” summit, but one of the two peaks that make up the saddle.

The first documented crossing of Bridger Pass was by the Stansbury Expedition, and it soon became a regular route in the area. At this point, the divide appears to split, offering some unique views.

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 Gallatin Valley, now known as Bridger Canyon, was referred to as "The Valley of Flowers" by Native Americans long before Lewis and Clark's arrival. Despite being claimed by the Blackfoot, it was recognized by all Indian tribes as neutral ground, signifying its historical importance as a meeting place and symbol of unity. Along this route you will be able to see the stunning landscape of mountains, rivers, valleys and meadows.

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.

North Cottonwood Trail is a really popular trail for the locals since it is off the beaten path enough to not attract huge crowds, but it still offers alpine access, meadows of wildflowers, and forested sections along the water. This is a really diverse trail that connects to other trails stretching all the way to the southern terminus of the Bridgers so you can make your hike as long as you like.
