The Honest One-Line Answer
Yes, you can — and it is one of the best nights Iceland offers. But almost every geothermal pool in the country closes its doors before the aurora reaches its best hours, and the two or three that stay open late are not the ones on the postcards.
We score 100+ Icelandic viewing spots every five minutes through the season, and ten of them are geothermal bathing sites — so we can rate each pool as an aurora location rather than as a spa. The answer changes a lot from one to the next.
The Closing-Time Problem
Aurora activity clusters around magnetic midnight, broadly 22:00 to 01:00 — the window we walk through hour by hour in the best time of night to see the northern lights. Now hold that against the doors.
Hours confirmed against each operator’s own site on 10 August 2026. They shift seasonally, so check on the day.
| Pool | Closes | Aurora verdict |
|---|---|---|
| Laugarvatn Fontana | 21:00 (11:00–21:00, Oct 1 – May 31) | Out of the water before the window opens |
| Hoffell Hot Tubs | 21:00, last booking 19:00 | Closes early, but see below |
| Hvammsvík | 22:00 | Ends as the window begins |
| GeoSea | 22:00 (opens 12:00) | Ends as the window begins |
| Earth Lagoon Mývatn | 23:00, shorter in winter | One of the two latest |
| Vök Baths | 23:00 | One of the two latest |
| Reykjadalur | No gate, no hours | Free hot river — but a 3 km hike |
| Drangsnes Hot Pots | Never | Free, 24 hours, year-round |
Note the shape of that list. The famous, comfortable, expensive pools shut at 21:00 or 22:00. The ones with no closing time are free, small and rural — the same reason they are better places to watch from.
There is one way around a closing time: a few operators sell combined aurora and geothermal-bath tours that include the pool as part of the trip, which is how you end up in warm water at the hour a normal ticket would have you leaving. GeoSea and the Forest Lagoon both appear in tours departing Akureyri.
One naming change worth knowing: Mývatn Nature Baths rebranded as Earth Lagoon Mývatn in September 2025 and reopened after a rebuild on 9 July 2026. Icelandic signage still says Jarðböðin.
Three Things the Water Does to Your Eyes
We covered this in depth for one specific pool in can you see the northern lights from the Blue Lagoon, and the physics does not change from site to site:
Spa lighting is deliberate. Any pool operating after dark lights its water, paths and bar for safety. Some dim during a display. Dimmed is not dark.
Steam sits between you and the sky. Warm vapour off 38°C water scatters light exactly where you are trying to look. A faint grey-green arc low on the horizon is the first thing it erases.
You cannot dark-adapt in a lit pool. Eyes need roughly 15–20 minutes of real darkness to resolve faint aurora, and one glance at a phone resets the clock. Our guide to what the aurora looks like to the naked eye explains why that matters — most nights deliver grey, not the saturated green of the photographs, and grey washes out first.
This is why light pollution ratings matter more than facilities. Fontana, Hvammsvík and Vök all rate medium in our data. Drangsnes, Hoffell, Reykjadalur and Earth Lagoon rate low.
The Pools That Actually Work
Drangsnes Hot Pots — three free tubs on the shoreline of a Westfjords village of under a hundred people, open around the clock all year, changing huts across the road. Low light pollution, an open northern sea horizon, and no closing time at all. This is the single best pool-plus-aurora combination in Iceland, and it costs nothing.
Hoffell Hot Tubs — four quiet tubs under Arnarbæli facing Hoffellsjökull, ten minutes off Route 1 east of Höfn. The 21:00 close is real, but guesthouse guests have access, which changes the calculation entirely. Pair it with Vestrahorn and Stokksnes half an hour down the road; stays around Höfn and the southeast are the ones worth booking for it.
Reykjadalur — a wild hot river above Hveragerði, free and ungated. The catch is the 3 km uphill hike each way, a different proposition on an icy December trail than on a July afternoon. Bring a headtorch you trust, or save it for early season.
The hot tub where you are already sleeping. Unglamorous and correct: unlimited hours, no crowd, no spa lighting, no drive home at 01:00 — the exact things a ticketed pool takes away. That is the argument our guide to choosing a dark-sky base makes at length.
In the north, Earth Lagoon’s 23:00 close is late enough to be useful if you are already nearby — see Mývatn and Húsavík aurora country, or stays near Mývatn for the tub-at-your-own-door version.
Two That Look Like Candidates and Are Not
Landmannalaugar has a famous natural bathing pool, and it is unreachable for almost the entire aurora season. Highland F-roads with river crossings, 4WD only, open roughly June to September. By the time it is dark enough to matter, the road is shut.
Gunnuhver is a hot spring you absolutely cannot get into. It is a field of boiling mud pots behind barriers on Reykjanes. It is a superb dark-sky viewing spot — just keep your clothes on.
Soak, Then Drive Fifteen Minutes
The move is not “pick a pool and hope.” It is scheduling. Book the early slot, get out at closing, and drive fifteen minutes to real darkness with the whole 22:00–01:00 peak still ahead of you. The pool and the aurora are not competing for the same hours — they sit back to back, and a night built that way is far better than either half alone. If you need wheels for the second half, you can compare cars and campervans across Icelandic suppliers.
Some links in this guide are affiliate links: we earn a commission if you book, at no extra cost to you. It never affects what we recommend or how we score a spot — including the part above where we tell you the free village hot pots beat the expensive lagoons.
Before you book the evening slot, check what the sky is actually doing. Our live aurora forecast scores each of these pools individually, so you can see whether tonight is worth planning around at all — and the Aurora Iceland app does the same for 100+ spots every five minutes, including the dark ones fifteen minutes down the road from the water.
