  description: Stent Road is Taranaki's crown jewel—a world-class right-hand point break that ranks among New Zealand's finest waves. The setup delivers everything: a hollow drop-in, a barrel section, and then a long, workable wall that lets surfers really unload. Set against the dramatic backdrop of Mount Taranaki's perfect volcanic cone, this wave has an atmosphere matched by few places on Earth. The boulder bottom demands respect and the local crew has earned theirs, but surfers who demonstrate patience and lineup etiquette will find one of the Pacific's most complete point break experiences. The drive through rolling farmland and wild coastline is part of the journey.
