Devils Postpile National Monument

The most pressing safety concern at Devils Postpile isn't the terrain — it's the surrounding Madera County crime rate, which sits at 526.5 violent incidents per 100,000 residents in 2023, well above national averages. For a remote monument accessed by a single shuttle road, that county-level figure means travelers should be thoughtful about when and where they stage their trip, particularly in gateway towns along the approach routes.

When planning your visit, keep valuables out of sight in your vehicle before boarding the mandatory shuttle at Mammoth Mountain Inn — smash-and-grab theft is a common pattern in high-traffic trailhead areas. Book campsites inside the monument rather than dispersing in less-monitored county land nearby, and if you're driving in during the early-morning private-vehicle window, travel with a charged phone and a downloaded offline map since cell coverage drops sharply past the Minaret Summit gate.
