Devil's Postpile National Monument, Mammoth Lakes Reviews

  • Devils Postpile NM contains one of the best examples of columnar basalt (the result of rapid lava cooling) in the country. One can stand near the base, looking upward at the 60 ft high nearly-perfect symmetrical columns, or hike above to stand on top of the volcanic rock's hexagonal geometric forms. Glacial polish adds to their beauty. The Devils Postpile Formation is simply amazing. Because of winter snow conditions in the Sierra Nevada Mountains, Devils Postpile has limited visitation times. Usually, the park opens in mid-June and closes by mid-October, but can vary from year to year. During peak summer season, the use of a mandatory shuttle bus is required to visit the park. The Reds Meadow/Devils Postpile shuttle begins at the Mammoth Mountain Main Lodge where plenty of parking is available. Fees are $7.00 per adult, $4.00 per child. There's much more to Devils Postpile NM than its namesake basalt columns. A small ranger station is located where the shuttle bus stops. From there, a 5 mile RT hike can take one to the 101 ft tall misty Rainbow Falls. Backpacking access into the high Sierra including the John Muir Wilderness and the Pacific Crest Trail happens here. Rafting and fishing are popular on the nearby San Joaquin River. So whether just taking the shuttle for an afternoon or planning an overnight adventure, Devils Postpile is certainly worth a visit.

  • A Wonder. During the summer they have a bus. Go later in October and you get to drive down the very narrow, windy and steep road, complete with sheer drop-offs. So of the drive doesn't bother you , once you reach the parking area it's only about a quarter mile to the post pile.. which is the name they have to unique lava basalt that cooled in a way that resulted in hexagonal columns.. Adventure further 2.25 miles and see the wonderful rainbow falls.... The post pile hike is easy. The falls are listed as easy-moderate We did it as a day trip from Bishop, ca. The road I described adds about an 45 minutes once you get to Mammoth.

  • If you come to Mammoth outside of ski season, Devil Postpile is a must! It's Gorgeous back here! There's a lot of short or long trails to pick from in the general area & it's ALL either beautiful, fascinating or both! The trail to Devil Postpile is a perfect little (0.4mile) rolling walk of a trail for someone as out of shape as me to be able to deal with. Worth the 20 or so minutes it took us to get from the Devil Postpile parking area to standing in front of the Devil Postpile itself. It was another thing all together to do the longer steeper Devil Postpile Loop Trail that lands you ON TOP of a couple different sections of the Postpile which is smooth and tile like & mind boggling! Ya gotta do this! Ya gotta LOVE God's Creation!

  • Not as amazing as Yosemite, but definitely worth a visit if you are at Mammoth Mountain during the summer months. A very unusual rock formation and some very nice, accessible hikes.

  • This is a great stop. A bit off the highway but well worth it. Even the winding mountain drive into the park is interesting and beautiful. There are several hikes of various distances but the walk to the Devil's Postpile is only half a mile. The Postpile is a very interesting phenomenon. Bring your camera and take lots of pictures, there was even a professional photographer there when we were there.
