Haleiwa is the gateway to Oahu's North Shore and the unofficial capital of Hawaiian surf culture. The small town sits at the mouth of the Anahulu River, where a photogenic rainbow bridge marks the start of a two-lane strip of surf shops, shave ice stands, food trucks, and art galleries. It feels a world apart from the high-rises of Honolulu and Waikiki, an hour's drive to the south. The Lili'uokalani Protestant Church on the river's edge has its own piece of Hawaiian royal history.
In winter, the North Shore transforms. The beaches between Haleiwa and Sunset Beach — including the Banzai Pipeline, the most famous wave in surfing — produce swells that draw the world's best surfers and crowds of spectators who line the sand to watch. Waimea Bay is the big-wave arena where "The Eddie" Aikau Invitational runs in waves over 30 feet — one of the sport's rarest and most celebrated events. Even if you do not surf, watching from the beach on a big day is unforgettable.
In summer the ocean calms and the same beaches become gentle enough for swimming and snorkelling. Behind Waimea Bay, Waimea Valley offers a walk through botanical gardens and Hawaiian archaeological sites to a waterfall with a swimming hole. The Pu'u o Mahuka Heiau — the largest heiau on Oahu — overlooks the bay from a hilltop. Back in town, Matsumoto's shave ice has been serving its rainbow-coloured cones since 1951 and always has a queue.
