Devils Postpile to Rainbow Falls

A globally renowned trek past a massive wall of symmetrical basalt columns, then down-canyon to a 101-foot waterfall that casts vivid rainbows in the afternoon mist. Wide accessible trail with minimal elevation change.

Rainbow Falls is outstanding. The shuttle is straightforward and the trail is flat and well-maintained. The rainbow effect at the falls is best in afternoon light.
