The tour begins with a visit to the Nesjavellir power plant, a geothermal area in the picturesque landscape of Lake Thingvallavatn (this part of the tour may not be included in winter). This really is "green" renewable energy, as more than half of Reykjavik's population gets its energy from the Nesjavellir geothermal plant.

Your tour also includes a visit to Thingvellir, where the Icelandic parliament Althingi was founded in 930, making it the oldest functioning parliament in the world. It is here that the slowly diverging tectonic plates of America and Europe meet.

Your tour continues to the beautiful waterfall of Gullfoss, a highlight of any visit to Iceland, along with the incredible spouting hot springs of Geysir and Strokkur. You will also visit Skalholt church, the ancient seat of the Icelandic bishops.

On your way back to Reykjavik you'll travel through fertile agricultural areas to the charming village of Hveragerdi.
