HT's

Mentawai, Indonesia
🪸Sharp reef🦈Sharks🏝️Remote

HT's (Hollow Trees, named for the casuarina trees on shore) is the Mentawai Islands' most famous right-hander—a long, mechanical barrel that peels down a pristine coral reef on Lance's Island. The wave offers everything from rippable walls on smaller days to death-defying tubes when it maxes out. Unlike some Mentawai breaks, HT's is remarkably consistent and handles a wide range of swell sizes. The takeoff is predictable, the barrels are forgiving by Indo standards, and the channel makes paddling out relatively easy. Many consider it the best all-round wave in the Mentawais.
