Banana Island Left

South Sumatra (Krui), Indonesia
🪸Sharp reef🚶Difficult access😮‍💨Hold-downs🏝️Remote

Banana Island Left is a fickle but heavy left reef break accessed by 15-minute boat ride from Krui on the south coast of Sumatra. The wave is a tube master's playground when it fires, producing sucky, pitching barrels over shallow reef in warm, clear water. Its fickle nature—requiring specific off-season W winds—keeps crowds minimal and rewards patient surfers who time their visit right. Expert surfing skills are essential.
