Haleʻiwa Historic District · Anahulu Stream Bridge (National Register of Historic Places, 1979)

The Anahulu River flows 6 miles down the Waiʻanae Range to Haleʻiwa Beach Park on Oahu’s North Shore, ending at the iconic Anahulu Bridge — a graceful concrete arch built in 1921 that has become one of Oahu’s most-photographed landmarks. The river is tidal and brackish in its lower reach, supporting one of the most popular kayak and stand-up paddleboard rentals in Hawaii. The slow lower mile is family-friendly flatwater with palm trees, mangroves, and views of the North Shore surf in the distance.
