Cobra

South Sipora, Mentawai, Indonesia
🪸Sharp reef

Cobra is a short, hollow slab just up the reef from Lance's Left in South Sipora, Mentawai Islands. The wave produces quick, intense barrel rides that demand expert-level tube riding and precise positioning. Its proximity to the iconic Lance's Right and Lance's Left makes it a convenient third option in the HT's area, offering a different character with its shorter, more intense barrel.
