The Arroyo Tapiado Mud Caves are located in the Carrizo Badlands of the Anza-Borrego Desert State Park. The “Mud Caves,” as they are called, are a popular attraction with adventure seekers.
The caves were created by water flowing through a thick deposit of silt. There are at least 22 caves, some up to 1,000 feet (300 m) in length and 80 feet (24 m) in height. A few of the caves include:
- Big Mud Cave: The only cave marked on most maps.
- Hidden Cave: Impossible to find without precise directions.
- Chasm Cave: A popular cave with a beautiful skylight.
- Carey’s Big Mud Cave: The largest cave in the arroyo.
- Plunge Pool Cave: A short cave that ends in a spectacular round room that towers above you.
- Dip Slope Cave: The small entrance is easy to miss.
Caution: There are some large open caverns you can explore, but most of the cave system is narrow and involves crawling through. The caves are made of mud which is prone to collapse. The ground is also very slippery.
Just be aware that exploring the caves solo is not recommended. Caves are dangerous places, and you should treat any trip inside them with the utmost respect. Remember the bring a flashlight.
