Asu is Indonesia's best-kept secret left—a pristine, barreling wave off a speck of an island in the Hinako group that few surfers ever reach. The journey here is an adventure in itself: flights, boat transfers, and basic island living, but the reward is potentially perfect waves with a handful of other surfers at most. The left reels along a coral-strewn reef, offering long, makeable barrels when the Indian Ocean delivers. Asu represents the ultimate surf trip ethos: go further, score better, embrace the simple life.
