White knuckle, single lane for 2 ways traffic down a windy, scary pass to get to the place. But well worth it with a reward of crazy formations.

Looks like three times indeed is a charm. The first two times in the last several years that I tried to visit this national monument, it was closed because of snow. I just got back from Devil's Postpile, and the weather was 55 degrees with a blue sky. You travel on a winding, narrow road to get to this attraction. The postpile of rocks is very unusual. Because of the time of year, there were only about a hundred people in the entire park. Unless you have a senior or annual pass, it costs $10.00 to enter, which you pay at the ranger station. There is plenty of hiking and beautiful scenery to keep you occupied for several hours at Devil's Postpile National Monument.

And worth the long and winding road down to the location. Much of the road is one lane with small turnouts along the way, so be prepared for that. The "postpile" itself is really quite amazing.

Really enjoyed seeing this area. Short .5 mile hike on good trail from parking and another 2 miles past we hiked to Rainbow Falls and Reds Meadow. Fall colors during visit made for great pictures.
