Great hiking experience, but the return hike from the Falls is steep in places. Many other hiking locations are available for both the John Muir Trail and the Pacific Crest Trail.

This is a wonderful and different place to visit because of the geological oddity found in a confined area. The impact of volcanic activity is amazing here. There are also two waterfalls to hike to and see if you are energetic enough. Rainbow Falls is...More

We are elderly and disabled so we were a bit apprehensive about the walk there, but it was fairly easy. Some rock and roots, but not bad. Some people were pushing strollers, too. All worth it as the post pile was very cool. Most people...More

We were looking forward to seeing this natural monument but after walking 10 minutes from the nearest available parking, seeing a 30 minute queue for a 30 minute bus ride each way we decided against it and finished up leaving. There are cable cars available...More

It's neat to see it in person, but pictures do tell the story. The shuttle ride down is faster than coming up. It's a single lane road for buses and a few cars for the campground on the same road, so there are a lot...More

Not sure, I would suggest checking out the Devils Postpile National Park website. They have all the pertinent info for the shuttle including cost, times, etc. Have fun and enjoy!
I'm confused about winter/spring activity at the Devils Postpile National Monument and hoping someone can clarify. I'm seeing a bunch of TripAdvisor reviews provided during winter months (Jan, Feb, Mar), but when I check the National Park website, it says that the site is closed (and shuttles don't run) and that it typically re-opens mid-June. We will be in the area while visiting Yosemite during the last week of May. If Tioga pass is open by then, we will use it to drive to Yellowstone and would like to briefly visit the Devils ... monument. If the site is not yet officially open when we're traveling through, might there still be a possibility that we could visit? How far would one have to hike in to get some of the views and how rigorous would the hiking be? Can this only be done with special gear (e.g., snow shoes)? What amount of time should be budgeted? Is there a place we could park our car while we hike? Thank you for any clarification you can provide.
