Don't just wander the surface of the earth — learn more about what's underneath it too. See surreal natural formations and patterns in the deep, dark recesses of Olympi Cave.
When you've finished at this natural underground attraction in Mastichochoria, why not check out The Chios Mastic Museum, Vroulidia Beach, and Mavra Volia Beach? They're near Olympi Cave and also popular with tourists.
