This is a moderate hike to a lake with a magnificent view. The trail starts at and follows Eagle Creek through the canyon. At 3.4 miles, after crossing Copper Creek there is a trail junction. Go left at this junction. The sign indicates the trail is not maintained. The trail is a bit rocky but otherwise good. From here, the trail starts climbing rapidly which makes it the toughest stretch. The trail does level out as it goes through a meadow near Heart Lake, although the lake is not visible from the trail. Then, the climbing begins again up the ridge above Heart Lake, where it tops out on the saddle where Arrow Lake lies just under 8000' elevation.
