Exploring the Cave of Swallows
In Exploring the Cave of Swallows, narrator Sir David Attenborough dives deep into the Cave of Swallows in Mexico, the largest cave shaft in the world. Despite its massive size, it was only fully explored two years before humans landed on the Moon. Caves remain some of the least explored places on Earth. However, humans are rarely the first to arrive in these dark, damp environments — many strange and fascinating creatures have already made them their home. This video is excerpted from BBC’s Planet Earth, a breathtaking documentary series that highlights the natural wonders of our planet.
