Pali o Pepeiao Trail

This is a remote, cairn-marked backcountry hike from the Hilina Pali Overlook down into the stark Kaʻū Desert, with sweeping pali-to-ocean vistas and a front‑row look at pāhoehoe and ʻaʻā lava. It’s an out-and-back of about 7.6 miles total to the Pepeiao area/cabin site and back. Expect exposure, wind, and rough footing on lava and volcanic ash.

The route drops off the Hilina Pali on switchbacks, then undulates across broad lava flows toward the historic Pepeiao site. The landscape is austere—black and rust-colored lava fields, scattered ʻōhiʻa and hardy shrubs, and big skies in every direction. On clear days you’ll catch the coastline far below. Navigation is by rock cairns (ahu) across open lava; in places the line can fade, especially in fog or low light.

There’s no water anywhere along this route and essentially no shade. Bring 2–3 liters per person, strong sun protection, and sturdy footwear—lava is sharp and unforgiving. Winds can be fierce along the pali; secure hats and anything that might sail away. Day hiking requires no permit, but overnight camping in this backcountry zone does. The historic Pepeiao Cabin is no longer safe for use—plan to camp in a tent if you’re backpacking.

Best time to hike: year-round, but go early morning or late afternoon for cooler temps, calmer winds, and better light. Avoid heavy rain or poor visibility, when slick rock and route-finding get dicey. If you want a bigger commitment, this area links to longer backcountry routes, but for many hikers the out-and-back to the Pepeiao area delivers plenty of solitude and scenery.

Bottom line: it’s rugged, exposed, and not for first-time visitors chasing lush jungle vibes. If you’re into geology, wide-open vistas, and quiet, this is one of the park’s most rewarding off-the-beaten-path hikes.
