Devils Postpile

About this spectacle

Devils Postpile is one of the world's finest examples of columnar basalt — a wall of near-perfect hexagonal columns rising up to 60 feet, formed when a lava flow cooled slowly and cracked into geometric precision. Visitors stand at the base of this natural colonnade, looking up at columns so regular they appear hand-carved. A short trail leads to the top of the formation, where glacial polish reveals a honeycomb mosaic underfoot. The site sits within a high Sierra valley at around 7,600 feet, surrounded by fragrant pine forest and the sound of the San Joaquin River nearby. In summer, the air is crisp and clear, and the dark basalt catches dramatic light in the morning hours. Rainbow Falls, a short hike downstream, rewards those who extend their visit. The combination of geological drama and mountain serenity makes this a compelling destination for both geology enthusiasts and casual hikers.
