“A historic long distance trail that provides many challenges with amazing views.”— Leslie Kehmeier
Along its length, the trail has fantastic views of St. Helens, Rainier, Adams with a few glimpses of Mt Hood. During the Ice Age, the area was heavily glaciated, evident by the knife-edge ridges and cirque basins seen from the route.
Due to its length and technical challenge, Boundary is often done as an out-and-back along portions of the trail or by shuttling to the end of the trail. There are significant climbs and descents throughout the route.
From Elk Pass to Badger Peak, there is a long, steady climb. From there to the south ridge below Craggy Peak, the route follows a more mellow grade to the east side of Hat Rock. The segments from Langille Ridge to the eastern end are a series of very steep climbs and descents through creek drainages, accessing Juniper Ridge Trail #261 and Dark Meadow Trail #263. Throughout the hike you'll have expansive views of the South Cascades in a very remote setting.
Be aware that from Bear Meadows until Council Lake the trail is shared with horses, motorcycles, and bicycles.
