Tunnels is Kauai's underwater wonderland—a reef break named for the lava tube formations beneath the surface that attract both surfers and snorkelers. The wave offers both lefts and rights over a complex reef system, with quality varying by section and swell direction. The north shore location means winter swells only, while the known shark activity adds an edge to every session. The stunning setting and varied peaks make Tunnels one of Kauai's most atmospheric surf experiences.
