Tips from locals
Open year round from 5 am to dark. May - October, go at sunset to see the bats emerge from the cave. Docents are usually on hand to share their knowledge. Very nice little 1/2 mile trail down the ravine. Next door to eclectic Alamo Springs Cafe if you work up an appetite.
For a truly magical experience (watching a bat emergence in a natural setting) you can visit Old Tunnel, a park that was created to preserve the native nursery bat colony which took up residence in an abandoned railroad tunnel. Witnessing the spectacular emergence of 3 million tiny bats is an unforgettable experience. This colony consists of Mexican free-fall and cave myotis bats, a nursery colony of mothers and babies. May thru October is when you can see them as they migrate south in winter. 45 minutes drive.

This is an old railroad tunnel which ceased operations in 1942. Since the shutdown of the railway, the tunnel has become a bat cave, hosting over 3 million Mexican free-tailed bats and 3000 cave myotis bats. The bats emerge at sunset during the months of May through October, and viewing is open to the public.
