Every one of these is free and every one of them is better before ten in the morning or after four in the afternoon.
Mokulēʻia. The stretch of coast west of Waialua, running out towards the end of the road. Long, exposed, unlifeguarded, and almost always empty. The polo fields are behind it and gliders circle over the airfield on a good afternoon. This is the one to drive to for sunset.
Kaʻena Point. Two and a half miles each way along an old railbed from the Mokulēʻia end, flat and unshaded, to a Natural Area Reserve behind a predator-proof fence: restored dunes, a Laysan albatross colony nesting from around November to July, and monk seals on the rocks. Go at first light, carry water, keep fifty feet from any seal.
Kawela Bay and the protected coves near Turtle Bay. Sheltered enough to swim in most conditions, which makes them the winter answer, and the ironwood shoreline walk between them is shaded — a rarity here.
Lāʻie Point at sunrise. A short basalt headland with a sea arch, reached through a residential street, facing east into the light. Ten minutes, quietly, park considerately, and do not climb towards the edge.
The Ehukai pillboxes. A steep, root-laced climb behind Ehukai Beach Park to old military lookouts with the whole Seven Mile Miracle laid out below. Not long, genuinely steep, and best early before the heat.
Waimea Valley at opening. The paved path up the valley is at its best in the first hour, before the tour groups, when the botanical collection is quiet and you can hear the stream.
Waialua. Half an hour among the old sugar mill buildings and the businesses that took them over — coffee, soap, surfboards. What Haleʻiwa would be without visitors.
