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.

we went camping in this area and then hiked to see Devils postpile. I think there's restricted access for cars, to minimize traffic and environmental damage. but there's a shuttle bus also.

We didn't know much about Mammoth and what to visit when we've been there and we saw some pictures online about the Rainbow Waterfall and we decided to give it a try. Really beautiful place! Worth visiting!

It's an short, easy hike to from the parking lot to the Postpile. The additional moderate hike to Rainbow Falls is well worth ti if you are so inclined especially in early to mid spring when there';s plenty of water coming through.

Beautiful views during the summer and east across to get to the trail that takes you to the post pile

The postpile itself, is quite impressive and I enjoyed taking a walk all over it, and spending some time overlooking the river from the bridge. ... thinking what a huge loss a small amount of dynamite could have caused.

A spectacular formation of rock, that gives a real insight to the wonders of volcanic activity. Nicely laid out and plenty of information points. A little hike from the bus stop. I saw a couple of very obese people who were struggling with the incline,...More

A must see for Mammoth, and it looks just like The Giant's Causeway in Ireland, with 1/10th of the tourists.

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.
