Not exactly secret, but still wonderfully secluded, this long, broad stretch of light sand below forested bluffs lies snugly between rocky points, with only a few cliff-top homes and Kilauea Point Lighthouse to the east providing signs of civilization. Although strong currents and high surf, especially in winter, make the water unsafe, tide pools at the west end invite exploration when the surf is low, creating beguiling mini-lagoons; a small artesian waterfall to the east is perfect for washing off salt water. Note: Despite its reputation as a safe haven for nudists (who hang out at the more remote eastern end), Kauai County does occasionally enforce the “no public nudity” law here. And as with all destinations where your car will be out of sight for extended periods, be sure to take your valuables with you. It’s a 15-minute walk downhill to the beach.
