Host Philippe Cousteau visits the amazing landscape of Croatia, which has some of the world's most amazing waterfalls and caves. At the Plitvice Lakes National Park, Philippe explores the ever changing lakes systems due to naturally forming dams. Philippe also discovers some large caves and sees how stalactites and stalagmites are formed. Then it's onto the island of Brac, which is famous for their limestone quarries. We visit a stone masonry school where students turn white limestone into beautiful works of art.
