The mysterious and beautiful Cava d’Ispica nature reserve and archaeological site is cradled in the Iblean Mountains of southeastern Sicily. Put on your hiking boots to walk among thousands of years of human history. An ancient river carved this gorge over millennia through a limestone shelf that is part of the African tectonic plate. (Yes, that means that this part of Sicily is technically part of Africa!) Occupied for centuries, caves and tombs–some dating as far back as 12,000 BCE–are cut into the rock shelf.
