It is an incredible place! Ask Sandy or anyone there to take you to see it. It is one of those things that is definitely off the beaten path!
The "Bat Cave" is one of the largest caves in the Little Bay area. Most everyone there knows about it. Years ago, Rusty, a friend of mine used to have a bike ride to the cave to celebrate the full moon.
A group of us non riders would head out early and set up candles and a sound system. The cave was lit up with almost a mystical semi-religious feel... (Better living through chemistry)
While those days are long over, most everyone in LB will still have stories from those days. Sandy will be able to help you!
