  • This is amazing place. You can see strange rock pillar and splendid waterfall. We met the big hail during the hike, but the view is really amazing. You can see yellow trees with snow ball on the ground. So pretty!

  • Made a special stop at Mammoth so we could spend the day at Devils Postpile national Monument. It was a fantastic hike a great area and the post pile itself was fascinating . Definitely worth the day . And the hiking was good too along the creek with rainbow Falls on the end and beautiful forest land. the trail was mostly effortless though there are some hills and elevation changes but overall well worth it .

  • It's definitely worth checking out ONCE, unless you're using it as a trail head start or end point. But really, if you're in the area go ahead and check it out that one time. On the way down to the trailhead you'll discover lots of nice scenery and good places to car camp.

  • We've been here several times. Easy hike from either of two parking areas. The postpiles themselves are a marvel of nature. This time we went in early fall with the trees turning colors. Beautiful scenery! Take a longer hike (2 miles?) and see Rainbow Falls while you're in the neighborhood.

  • Beautiful piece of nature and very special to see. The hike is very easy up to the monument. After this you can walk further to a beautiful waterfall. Definitely worth a visit if you are in the area.
