Papohaku Beach
One of the most sensational beaches in Hawaii, Papohaku is a 3-mile-long strip of white sand—so much so that Honolulu once purchased bargeloads of it to replenish the sand at Waikiki Beach. A shady beach park just inland is the site of the Ka Hula Piko Festival, held each year in May. The park is also a great sunset-facing spot that's perfect for a rustic afternoon barbecue. A park ranger patrols the area periodically. Swimming is not recommended, except on exceptionally calm summer days, as there's a dangerous undertow. Amenities: showers; toilets. Best for: sunset; walking.
