This is a lava tube near Bend, Oregon. It was closed to the public in 2006 to protect the bat colony living there, but the Forest Service recently allowed public access on only 2 Sundays this summer. There were alot of people exploring the cave this day.

The cave is 3000 feet long, however as you see in the video, it's gated.
