Tucked away toward the top of New Zealand’s beautiful North Island, the Bay of Islands are the gateway to some of the country’s most impressive coastal terrain. At the end of the 141-mile (227-kilometer) drive north from Auckland to Paihia, the islands loom into view, giving visitors their first glimpse of the spectacular scenery that awaits. The farther north you go, the prettier the vistas become. A full experience involves delving deep into the landscape, and tours can help you do just that, whether you want to charge into a rainforest, take to the sea in a boat or kayak, or soar above the islands on a parasail flight. Trekking through the Puketi Rainforest—home to a diverse range of native plant and animal life—is even better with a guide, who can point out the different species of flora and fauna. Take a scenic flight over rugged Cape Reinga, or watch the waves for dolphins on a sightseeing boat cruise. If your time is limited, a private Bay of Islands Tour can help you hit the region's highlights, combining activities such as wine tasting with sites like the Waitangi Treaty Grounds, where British colonists and Maori chiefs signed the Waitangi Treaty in 1840.
