Two miles downstream from Devils Postpile, the San Joaquin River tumbles over an abrupt 101-foot drop, sending rainbows of color into the mist. After the easy 1.5-mile walk to Rainbow Falls from the Reds Meadow area, the roar of the falls and the refreshing mists invite you to stay and enjoy a picnic lunch. Be sure to bring your camera—midday, when the sun is highest, is the best time capture the rainbows for which the falls are named.
The Devils Postpile and Rainbow Falls / Reds Meadow area is located 10 miles past Mammoth Mountain Ski Area's Main Lodge on State Highway 203. A mandatory shuttle bus is required during the busy summer months and departs from the Adventure Center at the base of Mammoth Mountain and The Village at Mammoth. Closed in winter.
