From a diving perspective, the highlight is Sardinia.
Just to the south of Corsica in the western Mediterranean, this
island is a mountainous slab of granite blessed with endless
white-sand coves, and offers some of the most exciting diving in
the Mediterranean. In 1960 the Aga Khan led a group of investors in
buying some 35 miles of its most stunning coastline, and proceeded
to transform it into what is now known as the Costa Smeralda or the
Emerald Coast, named after the distinctive colour of the island's
surrounding waters. The diving around this part of the island, and
off the coast on the Maddalena Islands is some of the best in
Sardinia itself offers aquarium-like diving conditions with
almost limitless visibility. Often described as the most exciting
diving in the Mediterranean, it is both varied and suitable for all
divers, from novices to the more experienced.
