Bintangs

South Sipora, Mentawai, Indonesia
🪸Sharp reef⚠️Shallow

Bintangs is a short, intense right-hander that breaks over an extremely shallow slab reef in South Sipora, Mentawai Islands. The wave demands technical precision, with a critical take-off leading into a quick, deep barrel over dry reef. Located near the iconic HT's, Bintangs offers a different challenge—shorter but more intense and consequential. Expert tube riders will find it exhilarating when the swell and tide align perfectly.
