Reykjanes Peninsula

Blue Lagoon

The Blue Lagoon sits in the middle of a lava field on the Reykjanes Peninsula, about 50 minutes from Reykjavík and 20 minutes from Keflavík Airport — which makes it a genuinely good first or last stop on your Iceland trip. The milky, mineral-rich water sits at a steady 37–40°C year-round, and yes, it really is that shade of blue.

The silica and algae in the geothermal water are the reason people keep coming back. You can scoop white silica mud straight from the lagoon walls and use it as a face mask, which sounds gimmicky until you try it. Book the Premium or Retreat packages if you want the full experience — they include the in-water bar, algae mask, and access to the quieter sections away from the main crowds.

Go early (doors open at 8am) or book the last entry slot of the day to avoid peak crowds. Advance booking is essential — the Blue Lagoon sells out days, sometimes weeks ahead, especially in summer and over the Christmas period. Prices start around 9,990 ISK for the Comfort entry, so factor this into your budget early.
