Deer Creek Lollipop (AZ)
Deer Creek from Indian Hollow, via the Thunder River Trail, is a classic marathon+ distance loop in the Grand Canyon. This is remote Grand Canyon backcountry with zero infrastructure; be prepared to be fully self-sufficient. The loop is popular with backpackers but rarely gets done in a push -- no wonder, because seeing Thunder River, Tapeats Creek and the Deer Creek Narrows will make you want to stop your watch and spend the night in there!
