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.
Trail Overview
This is one of the most accessible spectacular hikes in California. The basalt columns at Devils Postpile are genuinely jaw-dropping and unlike anything else in the Sierra. 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.
