At the base of the rugged, dramatic mountains of Rarotonga lies Avarua, a modest capital boasting a number of bustling outdoor markets, several restaurants and bars, boutiques and the National Museum of the Cook Islands. Along the Main Street you will find fine handicrafts and perfumes, as well as the black pearls for which the area is known. Although conditions are rarely reliable for swimming, there are dive sites in the area, including the famous Wreck of the Matai.
