Valley of the Temples, Agrigento

The remains of the ancient Greek city of Akragas, with some of the best-preserved Greek temples outside Greece, standing along a ridge above the sea in southern Sicily. The Temple of Concordia, from the 5th century BC, is almost complete. The site is a UNESCO World Heritage Site.

Allow half a day and walk between the temples among olive and almond trees; the Kolymbethra Garden is a lush garden in an ancient pool. Go early or late in summer, when it's very hot, or see it lit up at night on summer evenings. The archaeological museum is excellent.
