Ustica is a tiny volcanic island located 52 km from Palermo, which is linked by a regular ferry service. This heavenly retreat offers everything you may expect from a Mediterranean island: hiking trails alongside the stunning grottos of the shoreline, crystal clear waters with natural pools, and exciting snorkelling and scuba diving opportunities, including an underwater archaeological trail with Roman artefacts.

A former German settlement, it became mostly Greek at the start of the 20th century. It wasn't long till the residents moved out and Greektown turned into a primarily commercial area, rich in restaurants, stores and cafeterias, rigorously Greek-themed.

If you could draw an almost perfect Robinson Crusoe style beach, Dolly would definitely be a contender. Natural food supplies, shelter, and a source of fresh water would keep most castaways happy, and this beach has been known to do just that. As you arrive, especially if you are the first person of the day, you may be drawn to the turtle tracks in the sand. You can follow them until you find the signs of a nest. Both hawksbill and green turtles have been spotted. At the northern end of the beach, the hills are marked by fantastic rock formations with plenty of resident seabirds. More interesting, though, are the sea-level rock pools. Waves crash over the golden-toned, stony reef edges, which doesn't discourage marine life. Red algae and small hard corals paint different colours across the surfaces, while small fish dart about between the pools. Tiny moray eels hunt in ankle-deep water, and if you stay still they will swim up to you. The opposing end of the beach has slightly deeper pools to explore. Depending on the tides, these allow safe, shallow swimming. Going over the rocks to the sea isn't advised, as currents can be strong.

For a look at the rich sea life in the area and around the world, check out the Fakieh Aquarium. It showcases a wide range of aquatic species, including turtles, sharks, an array of colourful fish and many more forms of marine life—the dolphin show should not be missed.
