What You Need To Know Before You Go Caving
Current Cave Closures
The reason for this closure is for the protection of maternity colonies of Townsend's Big-eared bats. Bats are important components of the ecosystem. They provide insect control and pollination of plants, among other functions. Maternity colonies, hibernating bats, and all roosting bats are very sensitive to human disturbance, such as entry into caves where bats are present. Disturbance can cause drastic declines in bat populations. Observations by National Park Service staff have documented the presence of maternity colonies of Townsend's Big-eared bats in the above-listed caves. This bat is listed by the State of California as a Species of Special Concern due to its extreme sensitivity to human disturbance. Through consultations with bat specialists, we have determined this temporary closure to be appropriate for bat protection.
Exploring the Caves
Many of the developed caves contain trails through the cave and stairways or ladders into the cave. Most of the developed caves are located along Cave Loop, a 2-mile road near the visitor center. Just a short walk from the visitor center, Mushpot Cave contains exhibits and is the only lighted cave at Lava Beds. Developed caves are divided into three groups based on their varying levels of difficulty in the hardest section of the cave: least, moderate, and most challenging.
These caves have relatively high ceilings and smoother floors or trails. At the very least you should use the following gear: flashlights, sturdy shoes, and head protection.
Least Challenging Caves:
These caves may involve stooping through low sections and/or rough floors. Additional safety gear is recommended for the more difficult spots, including: cave maps, compass, kneepads, and gloves.
Moderately Challenging Caves:
These caves have some portions which require crawling. Using all recommended safety gear will protect you from injury.

How The Caves Were Formed
Lava Beds National Monument sits on the north face of the Medicine Lake Shield Volcano. The lava tube caves found here were created by flows of smooth lava 10,500 to 65,000 years ago. As the lava flowed it began to cool and solidify on the top and sides. Once the eruption ceased, the tube emptied and drained, and a new lava tube cave is left behind. As the rock cooled, the inner surface of the tube cracked and collapsed, producing openings to the surface.
If you wish to see a lava tube form today, you can take a peak into Lava Beds past by viewing a video of a similar volcano which erupted recently enough for people to be able to capture it on film.
Home To Live In
After cooling, these lava tubes became homes for unique cave life to thrive. When exploring, you may be lucky enough to spot some cave creatures, such as a cave cricket, rubber boa, millipede, or bats. These creatures are not poisonous or dangerous to humans, treat them with respect.
