Join Us on Cave Trips

It’s super easy to sign up for a trip. Come say hello at a meeting or send us an email if you’re right on time. Share with us your interest and caving experience. Could be none. Could be tons. We want to get to know you.

Check the calendar for an upcoming trip and wait for the trip leader to send you more info. That’s it. You’ll be caving in no time.


There’s so much to learn about caves. Whether it’s on conservation, preservation, geology, fault zones, or people, we strive to share what we know with you.

Explore Caving

Come visit a grotto meeting and get signed up for a trip. Monthly trips to caves for both beginners and long time cavers focus on our core values of conservation, exploration, preservation, and the protection of caves. All are welcome.
