Subway Cave is a section of lava tube about a third of a mile long, located between two areas of ceiling cave-ins. Large concrete steps have been constructed at both ends of the cave, providing easy access. The entrance is known as the Devil’s Doorway (N 40° 41.164' W 121° 25.135') and the exit is known as Rattlesnake Collapse (N 40° 41.060' W 121° 25.045').
Cave is accessed from the Subway Cave Trailhead which provides parking, picnic tables, toilets, and drinking water. There are interpretive signs along the short access trail and inside the cave.
About 24,000 years ago (USGS date of 24±6 ka) an eruption fluid basalt from a chain of spatter cones occurred about 2 miles south of here. Some of the vents can be visited along the Spatter Cone Trail. The spatter cones fed flow which extend nearly 18 miles north of the vents. The distal flows were fed be lava tubes such as the small segment accessible at Subway Cave. For more information visit the nearby Old Station Visitor Center.
