My husband and I were in Mammoth Lakes for one day while traveling to Yosemite. We passed a sign for the Devils Postpile Monument and since neither of us had ever heard of it we decided to check it out. So happy we did! What...More

Arrived at the designated bus shuttle start point today (12 July) to find the road is closed. The sign dated 7 July 2017 said that following a storm which damaged the road it's closed until further notice. Being reasonably fit we wondered about walking but...More

Short hike, less than 2 miles, from Red's Meadow. This rock formation is unlike anything else I've seen in the US. Very similar to the Giant's Causeway in Northern Ireland. If you hike an extra 2 miles, you can see Rainbow Falls, which is also...More

Great hike to devils postpile, make sure you go to the top (If you're fit). Great to see and the rock formations are out of this world.

About a 3 mile or so hike, but well worth it. You must keep going to rainbow falls. We took the two dogs and a potbelly pig and they love it.

This is a very cool place. I didn't know Devil's Postpile existed until I started researching the John Muir Trail. Once I found out about it, I knew we'd have to stop and take a walk around. You'll need at most an hour or so...More

While the drive into the park is windy, it is much easier and shorter than the roads around Yosemite and some of the other access roads to see redwoods, etc. in CA. The views along the road are really pretty - gorgeous forest views. Once...More

If you are in the Mammoth/Yosemite area, spend the day in the Deveils PostPile NM. Park at Mammoth Mountain, then take a shuttle around to see the sites. Definitely take a Ranger walk to the Postpile and hike on your own to see Rainbow Falls.

Great time. This is a must see. You need to hike a bit so takes lots of water.. As long as you are out there, might as well hike to Rainbow Falls.

Definitely a must see if you visit Mammoth Lakes. Take the shuttle down to Reds Meadows and it's a short hike. Really cool formations.

Questions & Answers
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.

No. this road is closed all Winter. It is one of the most beautiful spots on earth and a must see when in Mammoth in late Spring through Fall.
