An archipelago of nearly 150 islands scattered across turquoise waters makes up the Bay of Islands, a jewel of Northland and one of New Zealand's most striking coastal destinations. This subtropical corner of the far north is a paradise for cruising, dolphin and whale watching, deep-sea fishing and water sports, with sheltered bays and secluded beaches reached by boat. The famous rock arch of the Hole in the Rock, off Piercy Island, is one of the most popular excursions. The region also holds deep historical significance: at Waitangi the Treaty of Waitangi was signed in 1840, the nation's founding document, now told in its cultural centre. The towns of Paihia and Russell, the country's first capital, offer fresh-fish restaurants and a relaxed atmosphere. Among crystal-clear sea, history and subtropical nature, the Bay of Islands invites unhurried sailing.
