Katakolon, Greece
Tucked into a forested valley in the western Peloponnese, Olympia was ancient Greece’s center for the worship of Zeus, as well as the birthplace of the original Olympic Games. The Games took place here every four years for over 1,100 years, and the ruins – which include a colossal stadium that was built for 20,000 spectators – are truly impressive. Just 20 miles away on the coast is Katakolon, the maritime gateway to Olympia.
