Lumahai is a beach on Kauai's northern shore. The beach became famous in the 1958 film South Pacific where Mitzi Gaynor "washed that man right out of her hair". Located off of Hawaii Route 560, Lumahai is also considered a highly picturesque area. Despite its appeal to tourists, the strong surf and currents make it extremely unsafe for swimming and surfing.
Take Hwy. 56 all the way north past the town of Hanalei and then look just past the 4 mile marker for a pullout near a sharp left hand turn. Park on the right side of the road and take the narrow but beautiful trail down to the beach.
