  description: Lakey Peak is one of Indonesia's most reliable and photogenic waves—a perfectly symmetrical A-frame that splits into quality left and right options. Located on Sumbawa's south coast (east of Lombok), Lakey produces textbook peaks with hollow, barreling sections on both sides. The dry season brings offshore SE trades, and the setup has developed into a full-fledged surf destination with accommodations and restaurants lining the beach. Indonesian perfection without the Bali crowds.
