The trail begins alongside Bear Lake and climbs westward towards Tyndall Gorge, passing Nymph Lake along the way. Past Nymph Lake the trails climbs again to Dream Lake. Once there, the trail moves up a southward slope into the Chaos Canyon drainage and arrives at Lake Haiyaha, located at timberline along Chaos Creek. The lake and Chaos Canyon are known for excellent bouldering.
Lots of scrambling in the summer over the last 1/4 mile to the lake, which is surrounded by large boulders.
Haiyaha – a Native American word for rock – aptly describes this secluded, boulder-riddled lake in lower Chaos Canyon.
