Welcome to the homepage of the Cascade Grotto! Since 1951, the Cascade Grotto has been promoting recreation in, education about, and conservation of the caves of the Pacific Northwest and beyond. We’re a local chapter of the National Speleological Society based in the Seattle area, and we’d love to share our interest in caving with you!
On our website you can:
- Learn About Us and what we do;
- Find out when our next meeting is;
- Find out how to join the Grotto.
- Contact Grotto representatives (coming soon)
All events are posted on our events page at:
We hope to see you underground!
Cascade Grotto is an all-volunteer, non-profit organization.
