Well worth the walk in to visit. In addition to viewing the formation from the bottom it is worthwhile to climb to the top to view the ends of the hexagonal columns.

Love Rainbow Falls! It's beautiful! The basalt columns are cool also. The park isn't working returning but is fun for a day!

It is a wonderful sight to see --- and equally fascinating from all angles. Definitely do the full loop, and if you have time, try and visit Rainbow Falls as well. The trails are well marked, the rangers are incredibly helpful, and the forest and...More

Hike to Devils Postpile Monument is very short if you get off at shuttle stop 6. Might as well do the Rainbow Falls hike onto Lower Falls for a nice leisurely, dog friendly, kid friendly hike. It took us 5 hours due to rest breaks...More

Devils postpile can be reached on foot or via the shuttle alighting at bus stop #6 as we did. This trail will take you to the base of the monument where a board displays information on how it was formed. Once visited, we made our...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.
