Inspirock Rating:
4.4/5 based on 650+ 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.

  • Went up on a cold day where storms were expected in afternoon so rangers were very cautious. $10 is a cheap price for all you see. Car parks are plentiful but it is missing a coffee outlet! Walk very ...  read more »
  • We went in early fall, so the leaves were changing colors, pretty. Caught fish in the stream, saw a bear, wife stung by bee. Really nice place to visit. 
  • We enjoyed the whole area and saw the postpile from the base, top, and for some of the best views, from across the river. A great national treasure. 
  • Accessable by Eastern Sierra Transit Shuttle. Only .4 miles to the postpile from the ranger station. Best thing to do is hike to the postpile, then to rainbow falls, and then finish up the hike at Reds Meadow Resort to catch the shuttle back out.
  • 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.
  • In most cases you have to take the shuttle bus. It is $7.00 per person, round trip. Better than driving on a one lane road. Enjoyed the hike to Devils Postpile. The hike to Rainbow Falls was move difficult than expected, but worth it.
  • This was a decent place to have a short hike. There is no shade on the hike path and the path is dusty which makes the hike little uncomfortable. Plan 2 bottles of water per person since it might get hot during day times. Plan hiking rainbow falls if you are going to devils postpile. Rainbow falls is approx 2 miles from postpile.
  • Such a marvelous and spectacular location. Do not miss an opportunity to go. Plenty of hiking and awe inspiring scenery.
