Turnagain Pass Trail - INHT

Area Status: Open
This area is Open

The Turnagain Pass Trail is a segment of the longer Iditarod National Historic Trail (INHT).

Turnagain Pass Trail is not open for over-the snow motorized use. However, the west-side of Turnagain Pass is open for motorized use and is a popular spot for snowmachiners and in season the parking lot is often crowded with vehicles and trailers. .

At the lower elevations to the south and north the trail winds through mixed spruce and hemlock forest as it gains elevation. The trail eventually rises above the alders to rolling subalpine terrain around the trail’s midpoint around Center Ridge and Tincan Mountain, at the top of Turnagain Pass. This subalpine region has plenty of opportunities for off-trail travel and primitive camping.

On its south side the trail crosses deep gorges at Bertha and Spokane Creeks, with impressive waterfalls nearby. In all the trail crosses five streams where bridges have not yet been constructed. If your timing is right and you have the proper experience and take the necessary precautions these creeks can all be forded, although it can take a bit of effort and presents serious hazards.
