Easy and short

if you're like me-- born and raised in the NJ watershed and New Orleans (6 feet BELOW sealevel)-- this is some serious elevation, as is all of Mammoth Mountain-- take. your. time. this is an easy trail, but it is not easy for those of us who are used to being at or below sea level. it will be frustrating to pace yourself, especially if you're athletic with hiking experience, but the top of the glacier-polished postpile is breathtaking-- I wish the photos I took could do it justice. for sea-levelers, I recommend walking to Rainbow Falls first, taking a 15 minute break, then moving toward the top of the postpile. The glacier-striated hexagonal columnar basalt up there looks like a damn-near perfect tile patio job. try to be on top of the postpile around golden hour-- real treat.

Cool little loop to see this amazing monument. We got off at Shuttle stop #6 and you can continue onto Rainbow Falls at the tail end of the loop. Steep incline to the top but if that's a problem you can just view it from below which is the main focus anyway. Air quality was fine despite the fires but it was dry, hot and windy so bring enough water.

We got in past the station before 7, and it was worth it. We could explore at our own pace and brought the dog (we didn’t have a muzzle for the shuttle). The monument is so unique, super easy, and surrounded by great views.

You won’t be able to drive to the trailhead. Take the shuttle at Mammoth Main base. $8 for the round trip. Bring your patience. Shuttle can take a while. Overall, really great hike! Not super crowded and a beautiful day.

This is a fun, easy hike. The views and geology are really amazing. As you leave the ranger station, you walk past a beautiful meadow then along the San Joaquin River before arriving at the base of the basaltic columns of Devils Postpile. There is a trail that continues on towards Rainbow Falls. We chose, instead, to take the loop to the top of the columns. The views from the top are worth the few extra minutes. Enjoy!
