Create an itinerary including Devils Postpile National Monument
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.

  • You can see Devils Postpile off the John Muir Trail but if you want to visit the ranger station you need to go off trail. Neat place to visit. It’s not far from Reds Meadows.

  • A must see if your in Mammoth. Great Hike to Rainbow falls. Go early because the temps are in the 80's during the day. Bring water and electrolytes. You need to take the Tram in witch starts at 9am. If you go before 7am, you can drive in on your own.
  • This might be a bit unusual to write. I want to thank everyone for their photos and reviews. Some of these places are not in my ability to visit. It is nice to see the photos and the reviews. I feel like I have visited the places and have been able to experience and see things I would not gave normally seen. Many thanks for your photos and reviews.
