Overview
Embark on a subterranean adventure into a fascinating lava tube. This self-guided exploration covers an approximate distance of one-third of a mile and offers a unique glimpse into volcanic geology.
Trail Features
Prepare to be enveloped in complete darkness within the cave system, making a reliable flashlight essential for navigation and discovery.
For your comfort and safety, it is highly recommended that you wear sturdy, closed-toe shoes to negotiate the uneven and jagged cave floor.
The interior of the lava tube maintains a consistently cool temperature of around 46 degrees Fahrenheit (approximately 8 degrees Celsius), so bringing a light jacket is advisable to prevent any discomfort from the chill. Visiting the Subway Caves after hiking Cinder Cone is a great way to cool off.
There are two side caverns off the main cavern, Licifer’s cul-de-sac and the Sanctum.
The lava tube is 16-17 feet tall throughout, so no need for hard hards, stooping, or crawling.
Rescrictions
Please note that pets are not permitted within the lava tube to preserve this underground environment and the safety of all visitors.
