Few national parks are this alive. Hawaiʻi Volcanoes protects two of the world's most active volcanoes — Kīlauea, one of the most active on Earth, and Mauna Loa, the largest — and the landscape changes by the month: new lava, fresh craters, steam rising from the ground beneath your feet. Kīlauea has been erupting in episodes from its summit crater, Halemaʻumaʻu, since December 2024, and by mid-2026 the park counts more than fifty separate eruptions in that run. When it's going, the after-dark glow over the caldera is unforgettable. When it's paused — and pauses last days or weeks — the steaming, sulfur-streaked caldera is awe enough.
It's also a park you drive through dramatic change. Chain of Craters Road drops nearly 3,700 feet over 18.8 one-way miles from cool summit rainforest to the bare black coast, past pit craters and lava fields, dead-ending where old flows once buried the road. Short trails reach a walk-through lava tube, the floor of a crater that was a churning lava lake in 1959, and the largest petroglyph field in Hawaiʻi. The summit is surprisingly cool and very wet — bring a rain shell and a layer even in summer.
And it's sacred ground. To Native Hawaiians this is the home of Pele, the volcano deity, and the park asks visitors to treat it that way: stay on trails, don't take rocks, don't disturb the offerings you may see. Eruptions start and stop on their own schedule, so the one rule of planning a visit is to check the current status the day you go — never assume you'll see flowing lava, and be ready to be amazed by everything else.
Hawaiʻi Volcanoes is a park where the roads get rearranged by the volcano. Chain of Craters Road runs almost nineteen miles from the summit down to the sea and stops where lava crossed it; Crater Rim Drive is no longer a circuit, because the stretch past Keanakākoʻi has been closed to cars since the summit collapses and is now a walking and cycling trail. On top of that, a two-year construction project at the summit is closing things off in rotation. This is one park where checking before you set off is not optional.
The road around Kīlauea's summit caldera, and no longer a full loop. It is open to traffic from Uēkahuna round to the junction with Chain of Craters Road. Crater Rim Drive West takes you to the Welcome Center, Kīlauea Overlook and Uēkahuna — the lots most likely to have space. Crater Rim Drive East takes you to Kīlauea Iki, Nāhuku, Devastation Trail and the top of Chain of Craters Road. The missing arc, from that junction to the closure near Keanakākoʻi, is foot and bike only.
Drops from the summit through old lava flows and pit craters to the Hōlei Sea Arch on the coast, losing about 3,700 feet on the way. It is a dead end — lava buried the far continuation toward Kalapana, which is now a hiking and biking trail — so it is nearly thirty-eight miles round trip. Vehicles over 26 feet long and 8 feet wide are not allowed on it, or on Crater Rim Drive East.
The belt road around the island, with the park entrance on it. Hilo is the closer side at about forty-five minutes; Kona is a couple of hours around the other way.
One of the strangest drives in the country: you descend through successive lava flows, each labeled with the year it arrived, until the road simply ends at a wall of hardened rock above the sea. The pull-offs are craters, and the ocean at the bottom is a hard edge with no beach.
TipThere is no fuel, food or water on the road, no shade at the bottom, and only vault toilets at Maunaulu and the end. Cell service is patchy; the emergency phone is at the Puʻuloa petroglyph trailhead. Take water, and leave the big rig behind — anything over 26 feet long and 8 feet wide is barred from this road.
A two-year summit construction project is causing rolling closures and delays
What's open still gets you to the steam vents, the caldera overlooks at Uēkahuna and Kīlauea Overlook, and the Kīlauea Iki and Nāhuku trailheads. The closed arc is closed because the ground moved in 2018, which is a fairly compelling reason, and it now carries walkers and cyclists out to Keanakākoʻi instead.
TipCheck the park's alerts page the morning you go — this is the one park where a page written last year can be wrong about which roads exist. Drive slowly and watch for nēnē: cars are the leading cause of adult deaths among the park's Hawaiian geese, and they stand in the road and the parking lots.
The fire-pit within Kīlauea's caldera and the heart of recent eruptions — lava and glow appear here when active, viewed from rim overlooks like Uēkahuna and Keanakākoʻi.
Insider tipGlow is far better after dark — check the USGS and park status that day, since activity comes and goes. The crater itself is closed; you look from the rim. Uēkahuna and Kīlauea Overlook are drive-up, on Crater Rim Drive West. Keanakākoʻi is not — it's a mile each way on foot or bike along a closed section of the old road from the Devastation Trail lot.
Plan a trip to this spot →A loop that descends through fern rainforest onto the solidified floor of a crater that was a churning lava lake in 1959 — steam still vents from the cracks.
Insider tipAbout 3.3 miles round trip with a ~400-foot descent, 2–3 hours. The Kīlauea Iki Overlook lot holds 64 cars and the Nāhuku lot only 14, so start from Devastation Trail or Puʻupuaʻi if you arrive late.
Plan a trip to this spot →A lit, walk-through lava tube around 500 years old, reached by a short loop through dripping rainforest — you enter over a new bridge installed in 2026.
Insider tipThe tube is lit 8 a.m. to 8 p.m.; outside those hours bring a torch. Its own lot has just 14 spaces, so come before 9 a.m. or after 5 p.m., or walk in from Kīlauea Iki Overlook. Watch your head — the ceiling is low in places.
Plan a trip to this spot →A stunning 18.8-mile descent of nearly 3,700 feet from rainforest to the black coast, past pit craters and vast lava fields, dead-ending at the sea.
Insider tipAllow 1.5–2 hours round trip, more if you stop, and remember it is a long climb back up. Fill the tank and the water bottles before you start.
Plan a trip to this spot →The largest petroglyph field in Hawaiʻi — some 23,000 carvings — reached by a short walk to a boardwalk near the end of Chain of Craters Road.
Insider tipStay on the boardwalk; the carvings are sacred and fragile. Pair it with the nearby Hōlei Sea Arch at the road's end.
Plan a trip to this spot →A short, paved, wheelchair- and stroller-friendly walk across a cinder field buried by the 1959 Kīlauea Iki eruption — a stark pumice moonscape.
Insider tipA mile round trip, about an hour, and the easiest thing in the park. Its lot is also the trailhead for the walk out to Keanakākoʻi.
Plan a trip to this spot →Two climates by elevation. The Kīlauea summit (~4,000 ft) is cool and very wet year-round — highs in the high 60s, chilly nights near 50°F, and roughly 8–10 feet of rain a year, often as mist and fog. The park reckons the summit runs 12 to 15 degrees cooler than sea level. The leeward south coast at the end of Chain of Craters Road is warm, breezy, and much drier. Bring rain gear and a warm layer for the summit even in summer; the coast can be sunny and hot the same afternoon.
One main entrance off Highway 11 serves the summit area; the separate Kahuku Unit to the south keeps limited hours. A two-year construction project at the summit means rolling closures — check alerts before you drive up.
Near Volcano town — about 45 minutes from Hilo, 2–2.5 hours from Kona. No timed entry; drive in anytime, which makes after-dark glow viewing easy when Kīlauea is active. The Kīlauea Visitor Center is shut for a two-year renovation, so start instead at the Welcome Center, 1.2 miles in on Crater Rim Drive West.
A separate southern section off Highway 11 with pastoral trails across older lava — quieter, limited hours.
One historic hotel sits on the caldera rim; campgrounds and the nearby village fill out the rest. The summit is cool and there's no gas in the park.
The only hotel inside the park, perched on the rim of Kīlauea caldera (some rooms see the glow when active) — 33 rooms and a restaurant, run by the park concessioner.
Booking tipOnly 33 rooms, and crater-view rooms sell out fast during eruptions — book months ahead.
A small town about a mile from the entrance with B&Bs, inns, vacation rentals, a few restaurants, a store, and — importantly — gas.
Booking tipFuel up and grab groceries here; there's no gas in the park and limited food.
Nāmakanipaio (tent sites + rustic A-frame cabins, concessioner-run) and primitive Kulanaokuaiki (9 walk-in sites, no water) — both cool and forested.
Booking tipReserve the cabins ahead and pack for cool nights; bring all your water for Kulanaokuaiki.
Is it erupting right now — will I see lava?
Probably, at some point. Kīlauea has been erupting from Halemaʻumaʻu in episodes since December 2024 — more than fifty of them so far — but the episodes are separated by pauses of days or weeks and an eruption can last only a few hours, so nothing is guaranteed. Check the live status the day you go (USGS Hawaiian Volcano Observatory webcams and updates, plus the park's alerts). When it's going, the after-dark glow from the rim overlooks is the highlight; when it's paused, the steaming caldera is still remarkable.
What does it cost, and can I pay cash?
$30 per vehicle (7 days), $25 motorcycle, $15 per person; a Hawaiʻi tri-park annual pass is $55. The park is cashless — bring a card.
Is it safe? What's vog?
When Kīlauea is active it releases volcanic smog ('vog') and sulfur dioxide that can be hazardous for people with respiratory or heart conditions, infants, and pregnant visitors. The park also warns about falling tephra during eruptions — it suggests eye protection, long sleeves and a dust mask for close-in viewing. Heed closures, stay on trails, and mind earth cracks, cliff edges, and hot ground.
When should I go, and what should I pack?
Any time — the park is open 24/7. The summit is cool and wet year-round (bring rain gear and a warm layer even in summer); the coast is warmer and drier. The drier season is roughly April–October. Arrive early or late in the day: the park sees about two million visitors a year and the popular lots can be full by 10 a.m. After dark is best for glow if there's an eruption, and it's also when parking frees up.
How many days do I need?
One full day hits the highlights. Two or more lets you drive the whole Chain of Craters Road (1.5–2 hours round trip on its own) and return after dark for the glow if Kīlauea is active.
How should I show respect here?
This is sacred ground — the home of Pele. Stay on marked trails, don't remove rocks or sand, and don't disturb petroglyphs or any offerings you come across.
Pick your vehicle, line up the stops on the way in and out, and carry the whole route in your pocket.
