Welcome to Cave Week 2025!

Cave Week is a great chance to enjoy, celebrate and learn about our National Park caves. National Park caves provide tons of family fun and adventures for hundreds of thousands of Americans each year.

More than 20 U.S. parks, several Parks Canada sites and NASA are participating in Cave Week via social media posts, cave tours, exhibits, school events, web pages and much more. To be involved in cave week join your nearby park's social media feed or follow their links below.

This year marks the 8th anniversary of Cave Week. The focus of the week is on caves and karst, their importance, geology, history, biology, current research, exploration, restoration, and promoting other sites across the US, Canada, and the world.

Share your #CaveWeek! Join the vibrant virtual community of stewards, educators, and cavers in celebrating #CaveWeek, and share opportunities to interact.
