Experiences included bathing in the Blue Lagoon hot baths (which are warmed by Iceland’s Geothermal energy) and visits to several huge and spectacular waterfalls, the Þingvellir rift valley and National park and a geothermal power station. Undoubtedly, the highlight of the trips was seeing the space weather phenomenon of the northern lights -even if it did mean standing in -20°C temperatures in the middle of the night to experience it!
