Bankvaults

Mentawai, Indonesia
🪸Sharp reef🏝️Remote🦈Sharks

Bankvaults is a playful right-hander in the heart of the Mentawai's famous Playgrounds zone—a wave that rewards smooth, flowing surfing with multiple linking sections. The reef setup creates a series of workable walls that connect when the swell direction and tide align, offering opportunities for big carves and occasional tube sections. It's less intense than nearby Lance's Right or Macaronis, making it an excellent option for intermediate to advanced surfers looking for quality waves without the hectic crowds or heavy consequences.
