Niihau, scuba dive the best of Kauai. Unique lava formations offer large caverns, coral gardens and interesting swim-thrus.
Marine life is diverse.
Passage across Kaulakahi Channel, from Kauai to Niihau and back, can be rough at the best of times. Seasport Divers' Niihau trips are, therefore, only scheduled for the normally calmer period that runs from late spring through early autumn. We do recommend that you book Niihau trips in advance. Trips run on Tuesdays and Fridays, weather conditions permitting. Due to the popularity of this trip and the seasonal availability, a credit card number is required to hold a reservation.
