The Blue Lagoon is a unique geothermal spa in a lava field south of Reykjavik. You'll have several unguided hours here to do as you please. Perhaps you'll take a relaxing bath or massage in the milky blue-green water of the huge outdoor lagoon. The waters have curative powers, and the sensation of lying in a warm outdoor spa surrounded by snowfields is uniquely relaxing. Swimming costumes, towels and bath robes are available for hire. If you'd prefer not to bathe, perhaps you'd like to take a walk in the Blue Lagoon's spectacular surroundings.

In the afternoon, the tour continues from Reykjavik with the Gulfoss and Geysir Express half-day trip. The tour begins with a visit to Thingvellir, a geologically unique place where the American and Eurasian tectonic plates meet. The Icelandic parliament Alpingi was established here in 930, and in 2004 Thingvellir was added to UNESCO's World Heritage List.

You will also see the majestic and beautiful waterfall Gullfoss, the incredible spouting hot springs of Geysir and Strokkur. After a visit to the village of Hveragerdi, with its large greenhouses cultivating all manner of fruit, vegetables and flowers, the tour returns to the capital.
