Best Caves to Explore in Lava Beds National Monument in a Day

The most unique thing about Lava Beds National Monument are its many lava tube caves, which were created by lava flows over a period of fifty thousand years from 10,000 to 60,000 years ago. As the lava flowed from the Medicine Lake volcano, the surface cooled and solidified. Underneath the surface, lava continued to flow to various areas, eventually emptying the “tube” underneath. Over the course of time, the rock cooled, cracked, and collapsed, producing openings to the surface. Today, there are over 700 lava tube caves in the National Monument, of which over twenty (20) can be explored.

One of the lesser known gems of the National Park system is Lava Beds National Monument. Established in 1925, the park is home to the largest concentration of lava tube caves in the United States. Currently, over seven hundred (700) separate caves have been discovered in the park, and over twenty of these caves are accessible to the general public. That's right: over twenty of the caves are accessible to visitors. While there are many amazing things about Lava Beds - petroglyphs, hiking trails along the Medicine Lake shield volcano, interpretive displays about the Modoc War and more, the caves are the signature attraction. Unlike many National and State Parks which discourage or limit exploration of underground features to pre-set guided tours, Lava Beds encourages exploration of its many caves. And, as a matter of fact, Rangers will "rent" flashlights (no charge with a valid Driver's License) and provide information about the conditions found in the various caves within the park. One of the easiest caves to explore in the park with an interesting geologic and cultural history is Skull Cave.
