We got there at an awkward time (a bit before 2 on Sunday) and were provided little info about the shuttle. $10 to get in. It was busy, even at this time in low season. We had to park at the very end, red meadows stop 10 and catch the shuttle which runs every 30 minutes. First stop 9 is... More

“One of my bucket list places”
5 of 5 stars Reviewed 2 days ago NEW

Very unusual geologic formation. Trails were nice, you could walk all around and on top of the formations. Wonderful place.

“Interesting natural formation ”
4 of 5 stars Reviewed 3 days ago NEW via mobile

Formed by an ancient lava lake cooling down with cracks to Basalt stone and forming hexagonally shaped 'posts', this is a very interesting natural formation. We parked directly at the 'Devil's Postpile Parking'. From there it's only a 400m trail. There are also other parking lots available with hikes a little longer but still easily accessible.

“Another awesome visit to the Monument”
5 of 5 stars Reviewed 4 days ago NEW via mobile

After many years, we drove into the Monument and hiked to it, and from there, made it to Rainbow Falls as well. Six miles in all, more strenuous than some might want to take on. But what a wonderful escape into this hideaway in God's creation.

“Fascinating Geology”
5 of 5 stars Reviewed 5 days ago NEW

Devils Postpile is a must visit in the Mammoth Lakes area. We saw it after a short (30-45 minutes) but very nice hike from Rainbow Falls. Once there plan on a 30 minute visit. Postpile is very similar to the Giants Causeway along the Northern Ireland coast, and it's interesting to see identical geologic processes at work in two very... More

“Interesting Place & Lots of Hiking Trails nearby - Do Monument early in the morning!”
4 of 5 stars Reviewed 6 days ago NEW

Devils Postpile and other parking lots along the 8 miles between the entrance station and Red Meadow at road's end fill up early, even mid week and shoulder season. Get an early start, or be prepared to ride the shuttle bus from up at Mammoth Mountain and not be able to stop where you want for scenery or hiking. There... More

“Unique”
5 of 5 stars Reviewed 1 week ago

We drove to the parking lot for the Devil's Postpile. The road is narrow. I see why there is a shuttle system for most of the year. The hike to the formation is .4 mile. There is a loop trail to the top. The trail continues on for about 2 miles to reach Rainbow Falls. The formation is unique.

“YOU HAVE TO GO!”
5 of 5 stars Reviewed 1 week ago

The shuttle was not running when we were there. Parking might not be that easy. But you just HAVE TO GO! Beautiful, strange volcanic shapes, lovely walk to and from the Postpile. Park rangers were knowledgeable; what we expect of course. We had great weather; sunny and mild. Devils Postpile is a quiz for the brain and a treat for... More

“Very cool!”
4 of 5 stars Reviewed 1 week ago

Been to Mammoth many times, but never ventured out to see the sights. The shuttle was closed for the season, so we drove ourselves, which is fine, except when oncoming traffic doesn't yield when they should- or someone thinks taking their travel trailer down there is a smart choice. Did I mention part of the road is one lane?? Anyway,... More
