It's a hidden treat for Phoenicians bat lovers. Located in the Biltmore/Camelback area, people can take a short walk to the cave..really it's a tunnel. There are signs with details about the bats. We went the night of the super moon and it's pretty cool to see the bats fly out of the tunnel and start flying over the canal to feed. There were hundreds of bats coming out of the tunnel the night we went. It was hard to capture a photo since they fly so fast! Just a few families and couples were there that evening. It's nice it's not too well known but worth an evening walk.
