Treasure Island
Treasure Island is a long, barreling right reef break and one of the standout waves in the remote Banyak Islands chain off northern Sumatra. The wave offers quality barrel rides with a consistency that makes it the go-to spot for surf charters visiting the area. The Banyak archipelago provides a raw, frontier-style surf experience far removed from the more established Mentawai circuit, with warm water and uncrowded lineups year-round.
