Over thirty trail heads provide access to the 1,303,477 acres of wilderness backcountry for hikers seeking to escape into primitive and pristine areas. Trails of easy, moderate and strenuous ability lead to Alpine lakes and creeks, the John Muir Trail and the Ansel Adams Wilderness.
Devil's Postpile National Monument is located in Red's Meadow. The columns of basalt were formed approx. 900,000 years ago when a lava flow slowed and began to cool and crack. Temperatures deep within the lava bed were uniform enough to produce six-sided columnar joints, 40 to 60 feet high resembling a giant pipe organ, polished to a shine by later glacial action.
Rainbow Falls is located downstream from the Devil's Postpile. The headwaters of the San Joaquin River flows over an abrupt 101-foot drop, sending rainbows of color into the midst. Truly a sight that is breathtaking short hike.
