Located in the scenic Eastern Sierra near Mammoth Lakes, Devils Postpile National Monument is a must-see destination for outdoor enthusiasts and nature lovers. Known for its unique, towering basalt columns, this hidden gem offers more than just striking geological formations. With its crystal-clear streams, lush meadows, and nearby Rainbow Falls, the area is a paradise for hikers, photographers, and anyone looking to explore California’s diverse landscape. Whether you’re planning a day trip or a weekend adventure, Devils Postpile promises an unforgettable experience in the heart of nature.
Devils Postpile was established as a National Monument in 1911, protecting the 60-foot-tall basalt columns that make up this natural wonder. The columns were formed around 100,000 years ago by cooling lava, which cracked into hexagonal shapes as it solidified. Today, the formation is considered one of the best examples of columnar basalt in the world. Located within the Inyo National Forest, the monument spans over 800 acres of protected wilderness.
Once part of Yosemite National Park, Devils Postpile was removed from the park’s boundaries in 1905 during the construction of a dam. Fortunately, local activists successfully campaigned to protect the formation from being quarried for construction material. Since then, it has remained a beloved destination for those seeking to witness this rare geological phenomenon firsthand. In addition to the impressive postpile, the monument is home to Rainbow Falls, one of the most beautiful waterfalls in the region.
