Sky Lagoon in Kópavogur

Sky Lagoon is the geothermal lagoon you can reach on a city bus: built on the Kársnes shore in Kópavogur, a 15-minute drive from central Reykjavík, with a long infinity edge facing the sea and a seven-step sauna-and-cold-water routine the operator calls the Skjól ritual. It suits the first or last evening of a trip, couples, and anyone who wants a lagoon without the drive to Reykjanes. Under-12s are not allowed in, and the price today could not be confirmed in krónur.

The figures, read today on skylagoon.com: winter hours from 21 October to 30 April are 10:00 to 21:00; 1 May to 20 June 10:00 to 22:00; 21 June to 20 August 9:00 to 23:00; 21 August to 20 October 9:00 to 22:00. Guests leave the water 30 minutes before closing; the ritual and Gelmir bar close an hour before. Holiday hours are published for 24–26 and 31 December and 1 January. The water is 38–40°C and at most 120 cm deep, and the operator recommends 1.5 to 2 hours. The booking page offered the Saman pass (ritual, public changing rooms) and the Sér pass (ritual, private changing rooms), but every price appeared in Danish kroner, from DKK 867.68 and DKK 1,041.33 per adult, with no krónur figure readable. The ISK price is therefore left as "check".

#The arithmetic

From a central Reykjavík bed: Harpa to Vesturvör 44–48 is 8.5 km and about 15 minutes each way by OSRM on OpenStreetMap. Two hours in the water and the ritual, 30 minutes of driving and a 15-minute buffer for a booked entry gives about 165 minutes, an evening rather than a day. Without a car, Hamraborg bus interchange is a five-minute taxi or about 30 minutes on foot, by the operator's figures. On the five-day South Coast and Golden Circle journey it fits the evening of day 1 or day 2; on the ten-day Ring Road the Reykjavík night of day 9.

#What goes wrong

The wind off the sea: the infinity edge faces open water, and on a stormy night the lagoon is a cold place to get out of. The cancellation rule is generous but formal, in writing to the reservations address at least 24 hours ahead for groups of ten or fewer. Purchases are made with a wristband linked to your card, which is easy to run up. Closing time arrives earlier than the posted hour, because the water empties 30 minutes before.

#Alternatives

The Reykjavík pool morning is the same warm water at municipal prices, with locals and lanes. Hvammsvík is quieter and further, in Hvalfjörður. The Blue Lagoon is the airport-side choice for the last day.
