Hilina Pali Overlook Loop

Hilina Pali Overlook Loop is an 8.1-mile circuit from the overlook down Hilina Pali, south to Kaʻaha, east on the connector, and back up to the overlook. That figure includes the short out-and-back from the connector junction to Kaʻaha’s shelter and shore. Published loop estimates differ, so treat 8.1 miles as a mapped planning figure rather than a surveyed park total. Allow six to eight hours; 7.5 is a practical estimate for the app, not a published time. This is a demanding backcountry hike, not a quick stroll from the viewpoint.

From Hilina Pali Overlook, the trail drops through 24 steep switchbacks in tall grass and scattered ʻōhiʻa. The footing is rocky and uneven, and cairns can be difficult to pick out when grass is high. A large ʻōhiʻa partway down is the only dependable shade on this slope. Near the base, the route crosses loose rubble from the 2018 eruption; the tread can be hard to distinguish there, especially on the uphill return.

At the lower junction, take Kaʻaha Trail south across hot lava and scrub to the coast. The cairn-marked line passes collapsed lava-tube openings, where the thin crust can be dangerous. At Kaʻaha, the primitive shelter and composting toilet sit inland from a rocky shoreline and protected cove; this is not a sandy beach. Return to the junction, then take the rough eastern connector, where sparse cairns and open ground make navigation slow. It rejoins Hilina Pali Trail for the climb back to the overlook.

Most of the coast and connector are exposed, with little shade. Plan around the heat: avoid the hottest part of the day and carry at least four quarts of water per person. The catchment tank at Kaʻaha may be empty, and its water needs treatment. Cairns can disappear in mist or darkness, so this is a poor route to start late or follow without a reliable map.

Kaʻaha has evidence of traditional Hawaiian settlement, including agricultural pits, house sites, petroglyphs, and stone game boards. Leave the structures untouched and avoid walking on or rubbing petroglyphs. Dogs are not allowed on park trails except service animals. An overnight stay at the campground requires a backcountry permit; the day hike itself is not a campsite reservation.

The overlook’s stone shelter, dry slope, and open ocean make a distinctive frame for the coast below. On the descent, the views open along both sides of the shoreline. Take the time to look, but keep your footing on the steep, loose sections.
