Devils Postpile National Monument, Mammoth Lakes
(4.4/5 based on 700+ reviews on the web)
See rare geometrically shaped basalt formations and 30 m (100 ft) tall waterfalls at Devils Postpile National Monument, which is within the Ansel Adams Wilderness. The formations were created 100,000 years ago when lava was flowing and cooling down and glaciers eroded, polished, and fragmented the basalt into long, symmetrical columns. Reaching 18 m (60 ft) high and ranging from 61 cm (2 ft) to 1.1 m (3.5 ft) in diameter, the formations give an impression of tall posts stacked in a pile. At the park, you can hike, camp, fish and go horseback riding. Look for animals, such as black bears, coyotes, and mule deer. You can explore on 13 km (8 mi) of trails on your own or on a guided tour.

  • We're blessed to have National Monuments and this one is a must for any traveler in the area as it makes for a great day of learning and fun for the whole family. And while you're there be sure to continue on to Rainbow Falls for an amazing view and beautiful scenery along the way. Enjoy! S-
  • Beautiful location and wonderful fellow travelers to mix with, I'd recommend a visit. Even if you are with a ortho-walking boot like I was, you can still enjoy. Thanks goes out to the Rangers who went above and beyond in helping my friends to pickup the "gimp" with the parking limits after the visit was done. Liked the constellation playing cards in the gift shop a lot too.
  • Such a marvelous and spectacular location. Do not miss an opportunity to go. Plenty of hiking and awe inspiring scenery.
  • Established in 1911 by presidential proclamation, Devils Postpile National Monument protects and preserves the Devils Postpile formation, the 101-foot high Rainbow Falls, and pristine mountain scenery. The formation is a rare sight in the geologic world and ranks as one of the world's finest examples of columnar basalt. Its columns tower 60 feet high and display an unusual symmetry.
  • a short walk to devils postpiles 600m. you should do the short hike to the top. impressive to see it from above.
