Know before you go
The bay, the heiau and a hard trail down.
Kealakekua Bay State Historical Park (7:00 am to 8:00 pm, free) holds Hikiau Heiau and the Nāpōʻopoʻo landing. The Captain Cook Monument at Kaʻawaloa is reached only on foot by the Kaʻawaloa Trail, or by permitted vessel. The bay is a Marine Life Conservation District; the whole thing is quieter, and better, before nine.
Access
- Nāpōʻopoʻo: the park's only restrooms; parking near the wharf. Launching from the wharf is prohibited. Hikiau Heiau stands on the shore here; visitors are asked not to go onto it.
- Kaʻawaloa Trail: begins on Nāpōʻopoʻo Road just below Highway 11, with limited roadside parking. About 1.9 miles and 1,300 feet of descent each way to the monument; the climb back is the hard part, in the afternoon heat.
- Kaʻawaloa by water: commercial kayak operators need a state permit and a registered vessel decal; landing at Kaʻawaloa is regulated. Check DLNR before renting.
Distance & terrain
Kaʻawaloa Trail about 3.8 miles round trip with 1,300 feet of climbing on the return; two to three hours. The shoreline between Nāpōʻopoʻo and Keʻei is a short, rough walk.
Water
None on the trail or at the monument. Restrooms only at Nāpōʻopoʻo.
Hazards
- Heat on the Kaʻawaloa descent, and the climb out with the sun on your back.
- Storm boulders cover the old sand at Nāpōʻopoʻo; footing is bad.
- Swell in the bay makes the shoreline rocks and the monument landing dangerous.
Respect
Hikiau Heiau remains a sacred site; view it from the shore. Kaʻawaloa Flats holds burial caves in the cliffs above the monument; they are closed. The dolphins that rest in the bay are protected: no approaching, no swimming toward them.

Mauka · the slope
Coffee and the slopes above the bay.
Above Kealakekua rises the South Kona coffee belt — the rare elevation, latitude, and volcanic soil combination that makes Kona coffee distinctive. The slope was once dense breadfruit and taro country; today it's farmed in patches between forest and pasture.
Mid · Hikiau Heiau
Hikiau Heiau, and the arrival of Captain Cook.
Hikiau Heiau sits at the south end of Kealakekua Bay. In January 1779, during the Makahiki season honoring Lono, Captain James Cook's ships entered the bay. He was received with ceremony at Hikiau. Within weeks the encounter had turned: on February 14, 1779, Cook was killed at Kaʻawaloa across the bay.

Kealakekua under the Kingdom.
After the 1848 Māhele — the Hawaiian Kingdom's land division — Kealakekua was among the ahupuaʻa retained as Crown Lands, the personal lands of Kamehameha III. When the Kingdom was overthrown in 1893, the Republic of Hawaiʻi declared all Crown and Government Lands public; in 1898 they were ceded to the United States. The status of those ʻāina ceded remains contested.
This site marks the Crown Lands boundary descriptively, from the state-published inventory, and cites: Kameʻeleihiwa, Native Land and Foreign Desires (1992), Appendix A; Osorio, Dismembering Lāhui (2002), Chapter 2.

Reef · the bay
Kealakekua Bay is a Marine Life Conservation District.
The bay's coral and reef-fish populations are among the most intact in the main Hawaiian islands. Take is prohibited; entry is regulated. The water clarity that captivated 18th-century sailors still holds.
Ocean · winter waters
The deepest part of the Humpback Sanctuary.
The seafloor off Kealakekua drops to more than 1,500 m within four miles. Humpback song, bottlenose dolphin pods, and occasional false killer whales pass through. Listening from the cliffs above the bay, especially at dawn, you can hear breaths on the surface a half-mile out.
