The Costa Smeralda is a coastal area and tourist destination in northern Sardinia, Italy, with a length of some 20 km, although the term originally designated only a small stretch in the commune of Arzachena. With white sand beaches, golf clubs, private jet and helicopter services, and exclusive hotels, the area has drawn celebrities, business leaders, and other affluent visitors. The main towns and villages in the area, built according to a detailed urban plan, are Porto Cervo, Liscia di Vacca, Capriccioli, and Romazzino. Archaeological sites include the Li Muri Giants' graves. Each September the Sardinia Cup sailing regatta is held off the coast. Polo matches are held between April and October at Gershan near Arzachena. Other attractions include a film festival in Tavolara and a vintage car rally.
