Puna Coast Trail to ʻĀpua Point

Puna Coast Trail to ʻĀpua Point is a 10.8-mile out-and-back from Puʻuloa across the exposed south coast. It follows old lava to the water and finishes at a small coconut grove above beaches and coves. Allow a full day; expect about six hours of walking before longer breaks. Published distance figures conflict: one trail listing gives 6.6 miles each way, while the mapped route and other hike descriptions support about 10.8 miles round trip. Treat the mileage as approximate, check the latest park map, and leave a margin. ʻĀpua is the day-hike turnaround; the coast trail continues farther toward Keauhou.

The route gradually descends from the Puʻuloa area toward the ocean, mainly over smooth pāhoehoe. Much of it is bare lava rather than a clear dirt tread, so follow the stone cairns and do not cut across the rock. Once you reach the coast, an old stone goat corral is a rare shade break. The final couple of miles to ʻĀpua cross more pāhoehoe, a short rough ʻaʻā section, and sandy dunes with naupaka.

A small stand of coconut palms marks the remote campsite above the shoreline. The coast has low beaches, coves, and lava arches; the surf can make the edge look inviting while remaining dangerous. For a photo, include the dark lava shelves with the breaking water so the picture shows how close the trail runs to the ocean. Protected green turtles rest on park beaches and hawksbills nest there, so keep clear of posted nesting areas.

There is no drinking water at ʻĀpua. Carry everything you need; the park recommends at least four quarts or liters per person per day for this coast. Shade is scarce, the wind can be strong, and uneven lava makes this a demanding walk. Strong rip currents make swimming unsafe. If you camp at ʻĀpua, you need a backcountry permit; ordinary pets are not allowed on park trails.
