Lost Lake Trail - INHT

Area Status: Open

The Lost Lake Trail is a segment of the longer Iditarod National Historic Trail (INHT).

7.3 mile hiking trail from mile 5 Seward Highway to Lost Lake. This trail climbs gradually through dense spruce forest to emerge after 2 miles on an open mountainside of meadows and brush offering spectacular views of nearby mountains. Leveling off after 4 miles the trail enters a subalpine area of wet meadows and hemlock groves then climbs up an alpine ridge cresting after 6 miles. From here are the first views of Lost Lake amid a panorama of near and distant mountains. The trail descends then follows the rolling alpine terrain around the east side of Lost Lake where it meets the Primrose Trail. Heavy winter snow can linger here until July.

Camping on Lost Lake is recommended at the designated campsites, some of which are equipped with bear boxes and pit toilets. Backpackers are strongly encouraged not to camp on the Lost Lake peninsulas so that tundra can grow back.

Fires are prohibited in alpine areas, where hemlocks grow slowly and the burns leave deep scars in the tundra. Leave No Trace ethics of camping out of view of the trail, packing out all trash, and burying human waste are necessary to keep this high use area pristine. Thank you for helping keep Lost Lake beautiful!
