Hawaii Trails

Kauai, HI: Waimea Canyon

Explore Hawaii's own Grand Canyon on this 2-mile out-and-back that travels into the depths of Waimea Canyon and passes postcard views at nearly every turn.

From Waimea Canyon Drive, start hiking east down Kukui Trail—make sure to turn left onto Iliau Nature Loop for a short .25-mile detour past extremely rare iliau plants and unobstructed views of Wailae Falls. After reconnecting with the Kukui Trail, hike along a blood red dirt path and tackle a steep descent down switchbacks into the depths of Waimea Canyon. Keep your camera handy—postcard-worthy views of the canyon and Kauai’s rugged interior are frequent. Hike down as far as you like, and then retrace your steps back to your car.
