Blue Lagoon Travel Guide

The Blue Lagoon sits in a black lava field on the Reykjanes Peninsula, about 45 minutes from Reykjavík, its milky-blue water supplied by the adjacent Svartsengi geothermal power plant. Rich in silica and minerals, the water stays at 37–39°C year-round. Smear yourself in the white silica mud piled in buckets around the pool edge, then soak in the steam as wind blows off the North Atlantic. Winter evenings, when steam rises into the dark and the lights glow, are unforgettable. Book ahead on the official site—slots sell out fast.

Fagradalsfjall on the Reykjanes Peninsula woke in March 2021 after some 800 years of silence, when lava began creeping out of the Geldingadalir valley a short hike from the road. It erupted again in 2022 and 2023, turning 'go watch the volcano' into a routine Icelandic outing. At night the slow-moving orange lava glows against black rock, lit by its own heat. When eruptions pause, as they often do, you simply walk over the fresh, still-warm lava field. Hiking boots and warm layers matter; some routes climb over steep, uneven terrain.
