## Route description

From Kailua-Kona, drive north on Highway 19 across the lava fields of the Kona coast for about 45 minutes to Kawaihae. Puʻukoholā Heiau National Historic Site preserves the large stone temple built by Kamehameha I in 1790–91; a short trail leads to viewpoints, as entry to the heiau is not allowed. Entry is free, and there is a small visitor center.

Highway 270 continues north along the Kohala coast to Hāwī and ends at the Pololū Valley Lookout, over a green valley with a black boulder beach. The trail down is steep and muddy, and parking is very limited, so come early. Return to Hāwī and take the Kohala Mountain Road (Highway 250) over the hills to Waimea for ranch views.

From Waimea, Highway 19 descends to Honokaʻa, and Highway 240 ends at the Waipiʻo Valley Lookout above a deep valley sacred to Hawaiians. The steep road into the valley is restricted to residents and permitted tours, so the lookout is the place to stop. Back on Highway 19, the Hāmākua Coast is lined with gulches, waterfalls and old sugar towns.

Near Honomū, a side road leads to ʻAkaka Falls State Park, where a paved loop through rain forest reaches a 442-foot waterfall; non-residents pay an entry and parking fee. In Hilo, Rainbow Falls tumbles over a lava cave and often shows a rainbow on sunny mornings. The whole route with side trips is about 170 miles; Hilo is the base for the drive to Volcano.
