Glacier Bay National Park

Glacier Bay National Park is one of the marquee hiking destinations in Alaska. The Trail Compass directory currently lists 10 trails inside the park boundary, totalling roughly 44 trail miles when added together. Whether you are visiting for an afternoon or a long weekend, the network includes options for nearly every fitness level.

By difficulty, the indexed trails here break down to about 5 easy, 3 moderate, 2 hard, and 0 expert routes. That mix makes Glacier Bay National Park a good fit for groups with varied stamina — a stronger party can take on a longer ridge or canyon route while companions enjoy a shorter loop near the visitor center, then meet up in the afternoon.

Glacier Bay National Park sits within the subarctic Alaska wilderness. The hiking season is typically mid-June through early September; outside that window, daylight, snowpack, and river crossings become serious limiters. Shoulder-season visits can be spectacular but require more flexibility: trailhead access roads in Alaska may close after early-season storms, and high-elevation routes can hold snow well past the end of spring. Always check the official park website for current conditions, fire restrictions, and any permit requirements before you go.

Wildlife you can expect on Glacier Bay National Park trails reflects the surrounding subarctic Alaska wilderness: grizzly and black bears, moose along the river bottoms, Dall sheep on the high ridges, caribou herds, and bald eagles overhead. Give every animal real space, store food properly, and never feed wildlife — habituation gets animals killed.

Arrive early to secure parking at popular trailheads, especially on weekends and holidays. Carry more water than you think you need, even on shorter hikes — Alaska weather can swing from cool morning shade to hot afternoon sun within a couple of hours. Cell service is limited inside the park boundary, so download offline maps in advance. Leave No Trace principles apply on every trail: stay on the established tread, pack out all food scraps, and give wildlife the space they need.
