Rainbow Falls Hiking Trail | Mammoth Lakes Hike
Rainbow Falls Hike Overview: If you are searching for an epic waterfall hike, Rainbow Falls is it! This beautiful Mammoth Lakes hike features a 102 foot-high waterfall and spectacular views of the surrounding National Park area. The Rainbow Falls area was formed after a volcanic explosion approximately 75,000 years ago. Geologists refer to these rocks that as platy rhyodacite, a type of extrusive volcanic rock.
Rainbow Falls is medium to moderate 5.5 round-trip mile hike. The trail starts along the same Pacific Crest Trail section that starts the Devils Postpile hike and continues onward along the San Joaquin River. The trail is well marked, but plan ahead and bring plenty of water as there are no aid stations along the trail.

Chris-the-Cheetah: EPIC! I try not to use that word to ofter, but Rainbow Falls is incredible! The hiking trail was fairly moderate and even suitable for a good trail run. I got to the water fall ahead of schedule, so I even had time to venture down to the bottom and dip my toes in the water!
