Sky Lagoon is a geothermal lagoon on the Kársnes shore in Kópavogur, minutes from central Reykjavík, built around its seven-step Skjól Ritual: the 38–40°C lagoon, a 5°C cold plunge, a sauna at 80–90°C with seaside windows (a classic and a phone-free one), a cold mist, a body scrub, a 46°C steam room and a crowberry elixir. Open daily 9:00–22:00 until 20 October and 10:00–21:00 in winter; ritual passes start at about USD 130.
