Every month on This Is Caving, Josh sits down with a seasoned caver to find out. You'll hear their best underground stories, from first discoveries to close calls, and learn about the projects they're part of today: cave rescue, long-term digging projects, scientific research and major expeditions to each corner of the world to name a few.

Whether you've never set foot in a cave or you've been caving for decades, you'll come away knowing more about the world beneath your feet and the people who can't stay out of it.
