Reykjavik hot springs, pool by pool

Reykjavik has no natural hot spring inside the city limits. What the city has instead is a network of municipal geothermal pools, and a paid lagoon on its edge, and travellers often assume the two are the same kind of thing. They are not. Anyone searching for Reykjavik hot springs usually means one of three products: the city pools that Icelanders use every day, the Sky Lagoon on the shore southeast of downtown, or the Secret Lagoon out on the Golden Circle route. This page settles what each one costs, who can get in, and how the doors actually work, starting with the cheapest and most local option first.

The city pools are unglamorous by design. Laugardalslaug, Sundhöllin and Vesturbæjarlaug are municipal facilities with hot tubs, lap lanes and steam rooms, built for residents rather than for a spa weekend. Sky Lagoon and the Secret Lagoon are commercial operations with a single geothermal pool, a bar or a ritual attached, and a price built around the experience rather than the swim.

Pools first, lagoons second

A common mistake is booking a lagoon before checking whether a city pool would do the job for a fraction of the cost. Reykjavik's city pools charge 1,500 ISK for an adult, 400 ISK for a child aged 10 to 17, and admit anyone under 10 free, under a fee schedule the City Council approved in April 2026 and put into effect on 5 May 2026. A ten-visit adult pass runs 7,000 ISK, which works out cheaper still per visit for a longer stay. Sky Lagoon's Saman pass starts at 14,990 ISK, close to ten times the pool door price for a single adult entry.

Reykjavik has several spas in Reykjavik built into hotels and standalone wellness centres, and these sit at a different price point again, closer to the lagoons than to the pools. The choice usually comes down to what a traveller wants from the visit: a lap swim and a hot tub among locals, or a longer ritual built around one geothermal pool. The city pools are functional, with lane swimming and a sauna alongside the hot tubs, while the commercial thermal baths Reykjavik visitors book tend to sell the whole afternoon as the product, with a bar, a viewing deck or a spa ritual included in the price.

What a lagoon ticket buys that a pool ticket does not

Travellers who compare only the entry fee miss what the higher price includes. A Sky Lagoon Reykjavik spa visit comes with the seven-step Skjol ritual: the lagoon itself, a cold plunge at 5 °C, a sauna, a cold mist, a body scrub, a steam room at 46 °C and a crowberry elixir to finish, taken in that order. The infinity edge runs 70 metres (230 ft) along the shoreline, and a visit is built to last 1.5 to 2 hours rather than a quick soak. None of that is available at a city pool, where the facility is a swim and a hot tub without a guided sequence.

For anyone specifically after public hot springs Reykjavik pools, the three main municipal sites cover most neighbourhoods: Laugardalslaug in the east, Sundhöllin downtown, and Vesturbæjarlaug in the west end. Towels are not included at the door of a city pool the way they are at Sky Lagoon, where every guest gets one free regardless of pass. The trade-off is straightforward: the pools are closer to daily Icelandic life and cost a tenth of the lagoon price, while the lagoons sell a longer, curated experience with extras built in.

Choosing by distance, not just price

Distance changes which option makes sense for a given day. Sky Lagoon sits about 7.5 km (4.7 miles) from central Reykjavik, roughly a 13-minute drive, and about 6 km on foot from Hlemmur square. The Blue Lagoon is further out, 49.2 km (30.6 miles) from Reykjavik and about a 50-minute drive, or 21 km and 15 minutes from Keflavik International Airport, which is why many itineraries fit it in on the way to or from a flight. Anyone weighing hot springs near Reykjavik against a Golden Circle detour should note that the Secret Lagoon sits on that route rather than close to the city itself, so a day built around the Golden Circle can add the lagoon without a separate trip.

City pools have no such calculation attached: all three named here sit inside Reykjavik's own neighbourhoods, reachable without a car. The Blue Lagoon return coach transfer from Reykjavik or Keflavik Airport costs 4,395 ISK on top of entry, a cost a city pool visit never carries since it needs no organised transfer at all.

Booking and closing times

Both major lagoons require pre-booked, timed entry; a transfer ticket alone does not admit anyone to either site. Sky Lagoon recommends advance booking though it may accept walk-ins subject to availability, while the Blue Lagoon treats pre-booking as essential. Reykjavik's own Reykjavik geothermal pools need no advance reservation at all: a visitor pays at the door and walks in during opening hours. That difference alone changes how a day gets planned, since a lagoon slot has to be fixed in advance and a pool visit does not.

Closing times also work differently. Sky Lagoon requires guests to be out of the water 30 minutes before the stated closing time, and its Skjol ritual and Gelmir bar stop serving 60 minutes before close. The Blue Lagoon applies the same 30-minute exit rule ahead of its own posted hours, which shift by season across the year. A city pool visit carries no such wind-down built into the ticket, since the facility is simply open or closed at its stated hours.

Etiquette that catches first-time visitors

The shower rule surprises most first-time visitors more than any price on this page. Every Reykjavik city thermal pools facility, and both Sky Lagoon and the Blue Lagoon, require a thorough naked shower before entering the water, with attendants who check. Skipping it, or rinsing only in a swimsuit, is the single fastest way to be turned back at the door. Swimsuits are required throughout; nudity is expected only in the pre-swim shower area, never in the pool itself.

Minimum ages differ sharply between products and are enforced rather than suggested. The Blue Lagoon allows children from age 2 with adult supervision required up to age 13, while Sky Lagoon admits nobody under 12 at all, with 12 to 14 year-olds needing an adult guardian. That single rule decides the choice for families with younger children: a family with an 8-year-old can visit the Blue Lagoon or a city pool but not Sky Lagoon, whatever else is on the itinerary.

Extras beyond the water

Some visitors expect a full spa menu at every geothermal site, and that is not how these places are built. Sky Lagoon's offering centres on the Skjol ritual rather than a separate treatment menu, while a massage Reykjavik visitor wants is more often found at a standalone hotel spa or wellness centre than at the lagoons themselves. The Blue Lagoon sells a group floating activity for 5,900 ISK per person as an add-on, which is closer to a guided extra than a massage treatment.

City pools carry none of these extras. What they offer instead is straightforward: lap lanes, hot tubs at varying temperatures, and in some cases a steam room, all included in the base entry fee with nothing further to book. For a traveller who wants a spa afternoon with a ritual and a bar, the lagoons are built for that. For a traveller who wants a swim and a hot soak the way a local would take one, the city pools do the job at a small fraction of the price.

Weighing the options together

Put side by side, the choice among the best thermal pools Reykjavik has to offer comes down to budget, time and who is travelling. A solo traveller or a couple with an afternoon free and a taste for a longer ritual is well served by Sky Lagoon, at 14,990 ISK for the Saman pass or 17,990 ISK for the Ser pass, plus the 70-metre infinity view built into the site itself. A family, or anyone on a tighter budget, gets more value at 1,500 ISK per adult and 400 ISK per child at a city pool, with a 7,000 ISK ten-visit pass available for a longer stay.

The Blue Lagoon sits between the two in some respects and above both in price, with entry from 11,990 ISK for the Comfort package and a location well outside the city that suits travellers already heading toward or from Keflavik Airport. Wheelchair access is available at both major lagoons: Sky Lagoon has a dedicated Accessibility Suite with lifts into the lagoon, cold plunge and turf house, while the Blue Lagoon has paved parking and walkways with about a 5-minute walk to the main building. Neither lagoon nor pool option is wrong; the figures above are what decide it for a given trip.

Common questions

Are Reykjavik's city pools worth visiting instead of a lagoon?

For a quick, inexpensive swim and hot tub, yes: the entry fee is a fraction of either lagoon's price, though the experience is functional rather than a curated ritual.

Can young children go to Sky Lagoon?

No. Sky Lagoon admits nobody under 12, and guests aged 12 to 14 need an adult guardian with them.

Do I need to book a city pool visit in advance?

No, city pools take walk-in visitors at the door during opening hours, unlike the two commercial lagoons.

Is a towel included at the city pools?

Towels are included at Sky Lagoon on every pass; city pool visitors should check locally rather than assume one comes with the entry fee.

Which is closer to central Reykjavik, Sky Lagoon or the Blue Lagoon?

Sky Lagoon, about 7.5 km (4.7 miles) out and a 13-minute drive, against 49.2 km (30.6 miles) and roughly 50 minutes for the Blue Lagoon.
