This place is incredible! Located in the middle of nowhere, California, it is not an easy access facility! During the tourist season a bus takes you to the Postpile down a narrow winding road from a ski resort. We went after the tourist season, so we got to drive the road ourselves. They warn you to get to the parking lot before 11:00 a.m. if you want to be sure of getting a place. From the parking area it s a 0.4 mile hike over fairly level ground to the site. The site is a tad more than 7,000 feet above sea level, so be ready for that.
