the North Shore of Oahu. Renowned for its legendary beaches, Haleiwa is a favorite refuge for Hawaii’s residents and a must-see for visitors.
Each winter, O‘ahu’s rugged North Shore serves up some of the largest and imposing ocean waves on the planet. Giant, storm-generated swells make their long trek across the northern Pacific to batter reef breaks and the area’s shoreline.
