The name means "the heat," and, indeed, this windy, barren coast lacks both shade and fresh water (or any man-made amenities). Pack water, wear sturdy closed-toe shoes, don sunscreen and a hat, and lock the car. The hike is along a rutted dirt road, mostly flat and nearly 3 miles long (one-way), ending at a rocky, sandy headland. It is here that Hawaiians believed the souls of the dead met with their family gods and, if judged worthy to enter the afterlife, leapt off into eternal darkness at Leina Kauhane, just south of the point. Note that the point can also be accessed by trail (the hike is about the same length) from West Oahu at the Keawaula entrance, off another part of Farrington Highway.
In summer and at low tide, the small coves offer bountiful shelling; in winter, don't venture near the water. Rare native plants dot the landscape, and seabirds like the Laysan albatross nest here. If you're lucky, you might spot seals sunbathing on the rocks. From November through March, watch for humpback whales spouting and breaching. Binoculars and a camera are highly recommended.
