Onomea Bay is on the coast near Papaikou, reached from Old Mamalahoa Highway. The County lists walking trails down to the bay: the Onomea Bay Trail leads on to the Alakahi Trail and the steep Donkey Trail. The Alakahi Trail follows the old Onomea Access Road along the sea cliff to Alakahi Stream and down to the shore. Parking is limited to the highway shoulder at the trailhead. Below are rocky and pebble beach areas, and the County warns of hazardous footing, waves, currents and cliffs. In high surf, strong currents can make the ocean unsafe for swimming, so stay out. DLNR's Na Ala Hele trails program has more information on the trails.
