Trail Miles

Forests Involved

The Iditarod National Historic Trail - Southern Trek (INHT) comprises 120 miles of trail in south central Alaska in close proximity to over half of the state’s population. People can get outside in the summer and winter and enjoy a broad spectrum of motorized and non-motorized opportunities in and around the Chugach National Forest and learn about historic sites of Alaska’s Gold Rush era.

Traversing alpine tundra and wetter meadow ecosystems in the northernmost temperate rain forest, the trail system is maintained to provide public access and to protect fragile natural and cultural resources. Current work on the Southern Trek includes restoration of the 120 miles of existing trail and development of new trail to connect the communities of Seward, Moose Pass, Whittier, and Girdwood. Partners, other agencies, and interns and volunteers from local communities are assisting the Forest Service with accomplishing critical trail maintenance activities and trail expansion projects.
