Scala dei Turchi
After the active volcanoes of Mount Etna and Stromboli, the tilted white "staircase" of the Scala dei Turchi cliff is the most stunning geological site in Sicily. Formed by eroded strata of pure white marl, with a silken, gold, sandy beach below, the cliff was allegedly named after the so-called Turkish (actually Saracen) pirates who plagued the Sicilian coast in the 16th century. The Scala and its beach are extraordinarily popular, so try to visit in the low season. If you don't want the hassle of going to the beach on a busy day, you can also catch some beautiful views from several lookout points along the road. Another option is to see the rock formations from the sea, with several tour operators offering boat rides. The best access is from the signposted paid car park just south of the cliff (follow the sign to Majata Beach/Ingresso Scala dei Turchi).
