   First of four pit craters in the opening 1.5 miles. Covers the pit-crater primer and previews Puhimau (0.9), thermal hotspot (1.3), and Koʻokoʻolau (1.5) so the driver doesn't need a separate trigger for each.

   Hilina Pali Junction

   Side-trip stop. User explicitly wants it included because the lookout is genuinely good, but framed honestly as a 30-minute detour each way.

   Temporary access change: NPS has scheduled shoulder work on Hilina Pali Road from September 14 through November 19. During that window, the road beyond Maunaiki Trailhead will close to motor vehicles from 6 AM to 4:30 PM Monday through Thursday. The full road opens outside work hours, including weekends and holidays. Hikers, bicyclists, and backcountry permit holders retain access during work but should expect delays. Check current NPS conditions before taking this detour.

   Devils Throat

   Small roadside pullout, unfenced 150×165 ft pit. Arrival narration previews Hiʻiaka (MM 2.5) and Pauahi (MM 3.1) so those don't need their own triggers.

   Approach Cue (~12-15 sec)

   Show transcript

   Coming up on the right in about a quarter mile, Devil's Throat—a small roadside pullout. Park on the shoulder, cross the road to a dirt path, and walk carefully to the edge of a 165-foot pit. No guardrails, crumbling edges.

   Arrival Narration (~45-60 sec)

   Show transcript

   You're standing at the edge of a pit, and the ground just ends. Devil's Throat is 150 feet wide and 165 feet deep—a collapse crater where magma drained and the earth fell in on itself. No fence, no railing, just air between you and the bottom. The edges aren't stable, so stay back from the lip. You're standing on the East Rift Zone of Kīlauea. The craters along this road—Hiʻiaka at mile 2.5, Pauahi at 3.1—line up like beads on a string, each one marking a point where magma pushed up or collapsed. This entire stretch sits on top of an active rift. Pauahi is the massive one, with a boardwalk that gives you a real view of its scale. Mauna Ulu comes up at mile 3.6. Stay back from the lip here, and keep moving makai—toward the ocean—down the road.

   Show transcript

   Mauna Ulu turnoff coming up on the left in about a quarter mile. Short spur road to a parking lot with a restroom. The Puʻu Huluhulu hike is one mile one-way and gives you a real sense of what fresh lava fields look like up close.

   Arrival Narration (~45-60 sec)

   Show transcript

   You're standing on volcanic ground that's still young—the black lava field around you came from Mauna Ulu, a vent that erupted between 1969 and 1974. That eruption built a 400-foot shield and pushed flows all the way down to the coast, erasing six miles of the old Chain of Craters Road beneath stone. The one-mile walk to Puʻu Huluhulu, a small cinder cone mauka of here (toward the mountain), crosses both sharp aʻā and smooth pahoehoe from those '74 flows. Watch for kīpukas—pockets of forest the lava split around instead of burying. You'll end on top of the cone with views toward Puʻu ʻŌʻō, the vent that kept Kīlauea erupting for 35 years starting in 1983. The trail markers are reflective because the path isn't always obvious on black rock. Pack water; there's no shade out here. When you head back to the car, Mau Loa O Mauna Ulu is the next stop, about two and a half miles down the road.

   Show transcript

   You're driving through the Mauna Ulu flows from '69 to '74. Forest used to grow here—now you're on a ribbon of asphalt cutting through black lava. The pahoehoe surface tells you the story if you watch it. Where it's ropy and twisted, the flow was still moving under a skin that had already cooled. Smooth sheets mean it spread out flat and solidified. See those dead tree trunks poking up? Those are lava trees. A flow wrapped around a living trunk, the wood burned away, and the lava kept the shape. Everything around you arrived here in living memory.

   You're heading into the pali descent now—pali means cliff in Hawaiian, and you're about to drop about two thousand feet from where you are down to the shoreline. The road cuts across the face of Hōlei Pali in switchbacks, so take it slow. The grade is steeper than it looks and there's almost no shoulder out here. As you get lower, the forest opens up and you'll see the coast spread out below you, ocean all the way to the horizon. You don't want to be the person tailgating a rental car that has just realized it's on a cliff.

   Coming up on the mauka side in about a half mile: Kealakomo Overlook. You'll see a wooden pavilion right on the edge of the pali, perched 2,000 feet above the sea. Handicapped-accessible. The serious descent starts after this point, so pull in and take a look.

   You're standing 2,000 feet above the sea, and the wind up here will knock you off balance—strong enough that it's a better place to lose your lunch than eat it. Look makai, toward the sea, and you're staring at black lava frozen mid-pour, the flow visible in actual waves down the pali face. Underneath all that rock is the former Kealakomo village site, covered by Maunaulu flows during the 1969–1974 eruption. The Naulu Trail starts here and connects to the Nāpau Crater Trail if you want a long day-hike. Most people spend ten minutes taking in the scale and moving on. Back on the road, you're about to start the real descent, and the hairpin turn at mile 11.5 catches people off guard, so take it slowly.

   You're coming down Hōlei Pali now, dropping fast. That hairpin at mile 11.5 is sharp—brake well before you hit it. By mile 12, you've dropped to about 1,000 feet and the landscape dries out noticeably. The road swings close to the ocean here. You'll see pullouts with coastal views along this stretch. If steam's rising offshore and the park's posted active lava alerts, that's where lava is entering the ocean. Most days it's just blue water against black rock cliffs. Alanui Kahiko pullout is at mile 13.7—that's where the old road shows through.

    As you continue toward the coastal turnaround, remember that older photographs show Hōlei Sea Arch here, but it collapsed in September 2026. Ahead, the lava fields meet the Pacific, and the road reaches its coastal end. Follow posted signs and barriers when you arrive. The cliffs are unstable, so keep well back from the edges and stay out of closed areas. We'll finish at the turnaround, then return along the same road toward the summit.

    At the coastal end of Chain of Craters Road, you may remember a photograph of a rock arch stretching into the Pacific. That was Hōlei Sea Arch. It has collapsed. The National Park Service confirmed that it was still standing on September 23, 2026, and had fallen by the night of September 27. The exact time is unknown. Take in the coastal scenery from permitted areas, following every posted barrier. The cliffs are unstable and can collapse without warning. Keep back from the edges, and don't enter the closed area to look for the arch's remains. When you're ready, return along the same road toward the summit, with the lava fields you passed on the way down ahead of you.

    You're headed back up now, and the drive back always feels faster once you've seen it once. The light's going to shift on you though — afternoon sun hitting the pali differently, shadows stretching across the rift zone. You'll probably see more steam rising off the summit caldera as things cool down. When you reach Crater Rim Drive, you've got options. Kīlauea Iki trailhead is right there if you've got energy left. The summit caldera overlooks and the old Jaggar Museum site are within a few miles, along with the Thurston Lava Tube. You covered about two percent of Hawaiʻi Volcanoes National Park today. Not bad work at all.
