Camping Near Hot Springs in Hawaii: Soak-and-Sleep Picks

Folks call the desk every spring asking me where to camp next to a hot spring in Hawaii, and I always have to break the news gentle. Hawaii isn't Yellowstone. It isn't even Oregon. The islands have geothermal heat sure enough — Kilauea's been reminding everyone of that for forty years — but developed, soakable hot springs you can pitch a tent beside? That list is short, and it got shorter in 2018 when the lava came through Puna.

I've been out to the Big Island three times visiting my sister in Hilo, and I'll tell you, the whole hot springs camping deal there is more complicated than most trip-planning blogs let on. So let's talk honest. Here's what's left, where you can actually sleep nearby, and what to do if the warm pond you drove three hours for is behind a lava flow.

What the 2018 Eruption Changed, and What It Didn't

Before 2018, the Puna coast on the Big Island had a nice little cluster of warm ponds. Ahalanui — folks called it the "warm pond" or Pualaa — was a county park where seawater mixed with geothermal heat in a walled-off pool. Kapoho tide pools up the road, same idea, tidepool system warmed from below. Both of them got buried under the Kilauea lower east rift eruption that summer. Just gone. Thirty feet of fresh basalt where there used to be swimming.

What survived, and what's actually new, is around Isaac Hale Beach Park at Pohoiki. The 2018 flow didn't bury Pohoiki but it rearranged it — pushed up a brand new black sand beach, closed the boat ramp, and created some fresh warm ponds back in the trees where groundwater meets the still-cooling rock. The water isn't as hot as the old Ahalanui was. More lukewarm than anything. But its there, and the campground at Isaac Hale reopened to permit holders.

The rest of the hot springs internet gossip you'll see — some blog from 2015 pointing you at Champagne Pond, say — needs a sanity check against current county park status. Call Hawaii County Parks and Recreation before you commit a day to driving down there.

Isaac Hale Beach Park (Pohoiki) — The One That Still Has Warm Water

Isaac Hale is a county park down at the end of Pohoiki Road, off Highway 137 in the Puna district. Nearest real town is Pahoa, about twenty minutes up the hill. This is the closest thing Hawaii has to a classic soak-and-sleep setup right now. You camp in the park with a county permit, walk down to the shore, and the warm ponds are a short bushwhack through the trees past the new black sand beach.

Fair warning though. The ponds here shift. Some seasons they're warmer, some they're barely tepid, and after big storms they can be murky or closed off entirely. Locals surf the break out front and the parking lot is busy on weekends. Used to be quieter — internet found it. My Border collie Sadie would hate the place honestly, too many people and not enough shade for a black-coated dog.

Camping is tent-only in practice and the facilities are basic. Pit toilets, cold outdoor rinse showers, picnic pavilions. You need the Hawaii County camping permit in hand before you show up — rangers do check and they'll turn you around if you don't have paper.

Camping in Hawaii Volcanoes National Park

Now, Volcanoes National Park doesn't have a hot spring you can soak in. I want that clear up front. What it has is the raw geothermal context — steam vents, sulphur banks, a crater that occasionally decides to light up. If the geology is what draws you to hot springs camping in the first place, this is where you base yourself. Pair a night at Pohoiki with two or three nights up at the park and you've got yourself a proper Big Island trip.

Two campgrounds inside the park:

• Nāmakanipaio Campground — off Highway 11 near park headquarters, around 4,000 feet. Cool at night, eucalyptus trees, grass tent sites. Run by Volcano House concession, reservable.
• Kulanaokuaiki Campground — down Hilina Pali Road, more primitive, no water, first-come-first-served last I checked. Quiet. The one I'd send my own family to if they wanted stars and no neighbors.
• Nāpau Crater backcountry — permit required, long hike in across old flows. Not for first-timers to the island.
• Kīpukapuaulu area — day use only but worth a wander if you're staying up top.
• Volcano village B&Bs — not camping, but a backup if the campgrounds are full. The village is right outside the entrance.

Elevation matters here. People fly in from Honolulu assuming Hawaii equals warm, show up at Nāmakanipaio in a 50-degree bag, and shiver all night. It gets into the forties up there. Check your sleeping bag rating before you pack — Big Island weather varies more by elevation than most of the lower 48. Current park conditions and alerts live on NPS.gov.

Other Campgrounds in the Neighborhood

If you strike out at Isaac Hale, or just want to spread the trip out, there's a handful of state and county campgrounds within reasonable driving distance of the Puna hot ponds. None of them have hot springs on site. I'm giving you them because the "soak-and-sleep" plan on this island usually means driving to the water during the day and sleeping somewhere nicer at night.

MacKenzie State Recreation Area sits right on Highway 137 between Pahoa and Isaac Hale. Ironwood forest on a lava sea cliff. No swimming — the ocean just slams the rocks — but the camping is free with a state permit through the Hawaii Division of State Parks. Primitive, exposed, and the mosquitoes in the ironwoods can get after you. Still, it's a short drive from the warm ponds.

Kalopa State Recreation Area is up on the Hamakua coast, nowhere near hot springs, but if you're circling the island its a lovely cool rainforest campground with cabins and tent sites. Good base for Waipio Valley.

Spencer Beach Park on the Kohala coast is calm swimming water, grassy camping, a county permit setup. No geothermal to speak of but you can rinse off in warm seawater, which is probably as close as half the island gets to a hot soak.

Up on Haleakalā on Maui and the other islands, you won't find hot springs camping at all. Kauai, Oahu, Molokai, Lanai — none of them. The young volcanic activity that heats groundwater is a Big Island story and that's where your trip belongs.

Permits, Timing, and the Fine Print

Three separate permitting systems to keep track of, which trips up a lot of visitors. I'll lay them out plain.

Hawaii County parks (Isaac Hale, Spencer, most beach parks) go through the county's online permit system. They have a per-night fee for non-residents and a max stay. Camping is generally allowed Friday through Wednesday with Thursday as a cleaning day at some parks — that rotation changes, so verify. The permit office in Hilo opens weekday mornings if you need to do it in person.

Hawaii state parks (MacKenzie, Kalopa, Nāpali on Kauai, etc) run through the DLNR online portal. Nāpali Coast permits on Kauai sell out fast if you're combining this with another island — those release on a schedule and the window moves, so don't trust what you read on an old blog, go to the source.

Volcanoes National Park campgrounds — Nāmakanipaio is through the Volcano House concessionaire, Kulanaokuaiki has its own rules. Backcountry needs a wilderness permit from the visitor center. Rec.gov carries some of this; check Recreation.gov before you plan.

Why so many separate systems? Because county, state, and federal land each do their own thing and nobody in Hawaii has ever been in a hurry to unify a permit website. Just build the extra half-hour into your trip planning. And dont assume walk-up works — it sometimes does, and sometimes you drive two hours to a locked gate.

Gear Notes for Big Island Camping

Camping on the Big Island is weirder gear-wise than people expect. Sea-level Puna is hot, humid, and buggy. The park at 4,000 feet is cold and wet. Mauna Kea access is above 9,000 feet and freezing. One trip can cover all of it.

Bring a tent with real bug netting and a full fly — I've had cheap mesh tents fail me in Puna rain, and I've had expensive ones leak when I didn't seam-seal them before flying over. If yours is old, test it in the yard first. Our tent category has notes on what holds up in persistent damp. A compact stove is fine for the park but at beach parks you'll want to check the fire regs — open fires are often restricted and propane is the easy way.

For the warm ponds themselves: water shoes are not optional. The new 2018 lava is sharp as broken glass and that's not an exaggeration. Reef-safe sunscreen is required by state law. And please rinse off before entering any pond — the ecology down there is already stressed. Our general gear list has the island-specific stuff flagged.

If you're pairing the trip with any hiking in the park, the hiking section and trail notes cover the Kīlauea Iki loop and a few of the longer ones out to the coast. Good country, those trails, but hot and dry on the lava.

Honest Take

If your heart is set on soaking in a wild hot spring under the stars with your tent twenty feet away, Hawaii is not your state. Idaho or Oregon or New Mexico are. What Hawaii offers now, after the 2018 eruption, is a couple of lukewarm ponds at Isaac Hale, a volcanic landscape at the national park that's unlike anywhere else, and some genuinely nice county camping on the Puna coast. If you can accept the trip for what it is instead of what Instagram sold you in 2016, you'll have a fine time. The soak-and-sleep combination is more "warm dip and drive back to camp" than "soak until midnight". That's just how it is now. Sadie would probably rather be in Montana anyway.
