Hilina Pali Trail

From the Hilina Pali Overlook, this trail plunges off the rim of Kīlauea’s south flank and into the Kaʻū Desert—an airy descent with endless lava plains, ocean horizons on clear days, and almost no shade. It’s raw, stark, and beautiful, but also punishing on the return. Expect rough lava underfoot and a big climb back to the rim.

Most backpackers follow the Hilina Pali Trail all the way to the coast at Halapē, roughly 7.5–8.0 miles one way (15–16 miles total if you return the same way). Strong day hikers sometimes tackle the full out-and-back, but many arrange a shuttle and hike out along the Puna Coast Trail to avoid the brutal climb back up the pali. If you want a shorter taste, you can drop about 2.2 miles one way to the primitive Hilina Pali campsite and turn around—still steep, still exposed, and a solid workout.

Footing is a mix of sharp ʻaʻā and slicker pāhoehoe lava with bouldery, sometimes overgrown stretches. The route is generally marked but crosses open lava and cinder, so keep an eye on cairns, especially in low visibility. There is no reliable water anywhere on the route or at coastal camps—carry everything you need. Backpackers must secure a wilderness permit for overnight camping.

Scenery leans geologic: you’ll trace the dramatic Hilina Pali escarpment and traverse broad lava fields shaped by eruptions and earthquakes that keep Kīlauea’s south flank on the move. In season, watch for hardy native plants (think ʻōhiʻa in patches) and, if you’re lucky, nēnē gliding by. Crowds are rare; solitude is the norm.

Best time to hike: Year‑round is possible, but spring and fall usually bring friendlier temperatures. Summer is blazing, windless, and exposed—start very early. Winter can be windy and cool on the rim. No matter the season, pack ample water, sun protection, and be realistic about the return climb. If your goal is Halapē, consider a shuttle exit via the coast to save your legs.

Bottom line: If you crave big volcanic vistas and don’t mind heat, exposure, and a serious climb, this is one of the park’s most rewarding rim‑to‑coast descents. If you want shade and an easy stroll, look elsewhere.
