Caves and corridors
Scramble, squeeze, and explore the hidden corridors and caves that make Joshua Tree unforgettable.
Caves and Corridors
Joshua Tree’s hidden world of granite passageways
Joshua Tree National Park isn’t home to traditional limestone caves — but it is famous for something just as magical: caves and corridors formed by massive granite blocks stacked, shifted, and wedged together over time.
These narrow passageways, hidden chambers, and slot canyons create a unique style of adventure found almost nowhere else. At Summit Climbing Guides, exploring these caves and corridors isn’t just something we guide — it’s something we actively discover, map, and develop.
What Are Caves and Corridors in Joshua Tree?
Unlike underground cave systems, Joshua Tree caves and corridors are formed above ground when enormous granite boulders settle and separate, creating:
Tight slots and squeezes
Chimney-style passages
Hidden rooms and crawl-throughs
Natural corridors between towering rock walls
These features are scattered throughout the park and often unmarked, unnamed, and easy to miss unless you know exactly where to look.
Some of Joshua Tree’s most famous examples include areas like the Chasm of Doom and Hall of Horrors, but many more remain quietly tucked away in the desert.
Why Caves and Corridors Are So Special
Caves and corridors offer a completely different way to experience Joshua Tree National Park.
Instead of hiking around the rocks, you explore through them.

🧗 Hands-on movement and problem solving
🌵 A sense of discovery and exploration
🪨 Intimate views of Joshua Tree’s granite formations
📸 Incredible light, shadow, and perspective
