Riley the BatHi! I’m Riley, Chief Executive Bat at Onondaga Cave. I’ve learned a lot, hanging out in the cave and in the forest too! Follow me on Twitter.

Watch this to see where Onondaga Cave ended up for 2015! How cool is that? All caves are amazing, but both Onondaga AND Cathedral Caves really are so beautiful, such rare gems. If you haven’t been to these caves, or if it’s been a long time, plan to visit them this year!
