Subway Cave Lava Tubes
- Description: These are about a 90 minute drive from Eagle Lake RV Park. They're old volcano tubes with a section about 1/3 of a mile long that can be walked through. Be sure to bring a flashlight or phone with light, though, once you round the corner by the entrance, it is pitch black inside.
