Trail #114 High Line

Area Status: Unreachable

This Trail Open to Hiker and Equestrian Use.

The High Line trail travels in a west-to-east direction around the north side of Mt. Adams within Mt. Adams Wilderness and rises in elevation from 6,000' to nearly 7,800'. The trail features spectacular views of Lyman and Lava Glaciers, as well as panoramic views of the Goat Rocks and Mt. Rainier. 

The trail begins on the Pacific Crest National Scenic Trail #2000, 1.2 miles north of Killen Creek Trail #113. From here to Foggy Flat the trail is a roller coaster, refusing to follow the contours and forcing you up and down over the terrain. The trail crosses glacial meltwater streams that form two branches of the Muddy Fork. These crossings can be difficult, especially in the afternoons when the glacial melt is greatest.

At 5.3 miles, the trail enters the Yakama Reservation. This section of the trail is maintained and managed by the Yakama Nation.
