Is Devils Postpile National Monument worth it?
Devils Postpile punches well above its modest footprint.
The centerpiece is a wall of columnar basalt columns rising up to 60 feet, a genuine geological rarity that most visitors have never seen anywhere else. Add a free entrance fee, 24-hour access during the short summer season, Rainbow Falls nearby, dark skies worth staying up for, and direct access to Sierra Nevada trail networks, and this small monument delivers serious value. The mid-June to mid-October window is tight, but for those who hit it right, this is one of California's most rewarding stops per square mile.
Who it is for
Hikers, geology enthusiasts, and families who want a memorable, low-cost Sierra Nevada base camp will love it. Serious backcountry seekers may find the monument itself too compact, but the surrounding trail access keeps them satisfied.
Highlights
- The columnar basalt formation itself, a 60-foot wall of symmetrical hexagonal columns that looks almost engineered
- Rainbow Falls, a 101-foot waterfall reachable on foot and one of the Sierra Nevada's most photogenic drops
- Exceptionally dark skies at 7,560 feet elevation, making late-night stargazing a genuine draw
- Horseback riding and fishing options that round out multi-day camping stays for families or groups
Editor's tipThe mandatory shuttle system from Mammoth Mountain limits car traffic inside the monument, so plan your arrival time around the shuttle schedule rather than driving in. Afternoon thunderstorms are common in July and August, so aim for the basalt formation and falls in the morning and save stargazing for clear nights after storms pass.
