Explore Anza Borrego Desert

students on mudcaving trip
It's like a completely different world in desert. The caving was awesome and I loved when the entire group turned off our lights and hiked out in the absolute dark! – participant

It’s time to get dirty!  The desert is full of adventure, mystery and surprises.  Our trip to Arroyo Tapiado Mud Caves in Anza Borrego Desert State Park can be described as thrilling! Stroll leisurely through some caves and push your limits while crawling through others as you explore some of the most expansive mud caves in the world. We'll check out some slot canyons and learn about the largest state park in California on this outing.  

Whether you are a seasoned desert traveler or brand new to the vast, exciting world of outdoor adventures, an afternoon exploring Anza Borrego is sure to incite in you a new appreciation for the unique state park to our east!

PLEASE NOTE: The caves are not closed to the public, but the park is not excited about all the attention they get.  Many visitors to this area are unprepared and often unaware of the environmental hazards present. The caves are ephermal - constantly changing and shifting over time - rain, floods and faulting all affect them.  They are dried mud with no support structure so could collapse at any given time. If you choose to enter make sure you have a reliable headlamp, hard hat, whistle, water bottle, and rope for safety equipment.  Most importantly, do not go in to explore alone and always tell someone where you are going and when you plan to return.  

Difficulty Level:

This trip is considered easy, with some portions of moderate difficulty. Many of the caves and slot canyons are large enough for us to hike through. Some will have sections that are more confined and require crawling, however, it is always the participants choice to pass through each cave.
