Family Friendly Mellow hiking as far as you want to go!

Plan accordingly for any sort of alpine weather as the upper portion of this trail is exposed to the elements & well above treeline. Significant amounts of snow may linger till mid-summer.

Description

From the Teton Canyon Trailhead, follow a straight shot on trail #027 all the way to Alaska Basin & Buck Mountain Pass, on the boundary of Grand Teton National Park.

The trail largely follows the beautiful South Teton Creek into the alpine zone of Alaska Basin. Expect incredible summer wildflowers and be on the lookout for moose and bear.

Though not commonly seen, this is grizzly habitat so be prepared with smart food storage practices & bear spray.

En route to Alaska Basin, the trail climbs steeply at times onto a series of benches. As you get into the Basin, you'll come upon incredible alpine lakes & waterfalls over ancient white granite. The trail is entirely doable, but you'll likely want to adopt a mellow pace to take in the flora, hydrology & geology that makes this area feel so unique.

Above Alaska Basin, you'll encounter the stunning Buck Mountain Pass, with its namesake looming high above you to the northeast. The trail is very well maintained, but expect some stimulating exposure & rocky terrain.

A few spots where it looks like an avalanche had piled up a bunch of snow are still there covering up the trail, but were easy to navigate. 5.7mi — 2h 30m
