Denali's longest trail, with bridges over two creeks and great views of three lakes. The surface is a mix of compacted gravel, soils, rocks, roots, and sections of planks over marshy ground. The trail is up to 20% grade at times, generally 24' wide. Note: The southern trailhead is located on the west side of Highway 3, about 7 miles south of the park entrance, near a bridge over the Nenana River.
