The 30-kilometre stretch of coast east of Whangarei, centred on the small harbour village of Tutukaka, is the launching point for trips to the Poor Knights Islands — a Marine Reserve regarded as one of the top dive sites in the world. Several operators run day trips year-round; even snorkelers can see large numbers of fish in the islands' clear water.
The coast itself is worth a half-day even without going in the water. Matapouri, Whale Bay, and Sandy Bay are some of Northland's best swimming beaches; Tutukaka harbour has good restaurants and a small marina. The coast road from Whangarei is winding but scenic.
