So we decided to join Reykjavik Excursion for full day excursion that lasted 8 hours. Having very poor meal last nite, we decided to have huge breakfast at the hotel. We have chosen "The Golden Circle"excursion. The name "Golden Circle" might be a tourist-industry tag, but it's also apt, as this broad circuit east from Reykjavik covers many Iceland's best known features and touches on the root of much of its history. The whole round trip is about 300km.We started by visiting Hellisheidi geothermal power plant, a high temperature geothermal area just 30 minutes drive from Reykjavik. This stop at the power station is very educational as we learnt that most heatings and hot water to all building in Iceland is supplied by geothermal plants. A further 1.5hours drive through the vast space of soutwest from Reykjavik brought us to the beautiful waterfall Gullfoss (Golden Fall), where we can walk so close to the edge that we felt the mist of the glacial water on our faces. This water fall plunges in 2 stage before dissapearing into huge gorge. Amazing really to see the volume of glacier waters being released into the gorge. One of the most beautiful waterfall I've seen.
