If you love exploring caves, Oregon has plenty to offer. Everyone is familiar with Oregon Caves National Monument, but there are other subterranean wonderlands around the state. A tour company offers adventures in these lava tube caves near Bend, and there’s another little-known cave that’s also a must-visit. Check out Derrick Cave:

Derrick Cave is managed by the Bureau of Land Management. You'll find it just south of Bend.

To reach the cave, travel on Highway 20 to Forest Road 23. You'll take a dirt road onto Road 2325, then drive until you reach a small parking lot. The dirt road is very rough, so take it slow.
The best way to enter the cave is right from the parking lot.

The large entrance is easy to walk right into! Make sure you're wearing some sturdy shoes, and bring along at least one light source (a second backup is always a good idea).

This lava tube cave was formed by volcanic activity thousands of years ago. It's 1,200 feet long - one of the longest in the state.
