🧖 Reykjanes Peninsula, Iceland
Things to do in The Blue Lagoon
Milky-blue geothermal waters in a black-lava field
A favourite for honeymoons
The Blue Lagoon is Iceland’s most famous geothermal spa — a surreal expanse of silica-rich, milky-blue water steaming in a black-lava field. It sits between Keflavík airport and Reykjavik, which makes it the perfect first or last stop on an Iceland trip rather than a city day out. Pre-booking is essential; it routinely sells out.
Steamy blue water, a swim-up bar and a couples’ spa glow — a romantic start or finish to Iceland.
Time needed
Half a day (2–3 hours in the water)
Best time
Year-round — it’s magical in winter with snow and a chance of Northern Lights, and lovely under the midnight sun in summer
Region
Reykjanes Peninsula, Iceland
Don’t miss
Soak in the geothermal lagoon
Float in the warm, mineral-blue water, slather on a silica mud mask from the swim-up bar, and unwind with the steam rising around you. Packages include a towel, a drink and the signature masks; premium tiers add a private changing area.

The Blue Lagoon tips
- Book your time slot well ahead — entry is timed and sells out, especially in summer and around holidays.
- Condition your hair and tie it up; the silica water is harsh on hair.
- Do it on your arrival or departure day to save a separate trip — it’s right by the airport.
