Famous because it's the beach where Nurse Nellie washes that man out of her hair in South Pacific, Lumahai Beach's setting is all you've ever dreamed Hawaii to be. That's the drawing card, and if you're adventurous and safety-conscious, a visit here is definitely worth it. The challenges are that it's hard to find, there's little parking, and there's a steep hike in; also, too many people misjudge the waves, even those never intending to set foot in the water. There's a year-round surge of onshore waves, massive sand movements (especially around the river mouth), and a steep foreshore assaulted by strong currents. Like the mythical creature from the deep, rogue waves have actually washed up on lava-rock outcroppings and pulled sightseers out to sea. Our advice: Look from the safety of the scenic overlook or walk on dry sand only. Or, take advange of Lumahai's length and find adequate parking 1/2 mi. further where the river comes in. Amenities: none. Best For: solitude; walking; sunset.
