“Fascinating tour around Iceland's most recently erupted volcano, lava fields and the Reykjanes peninsula geothermal area. Our guide, Elias, was friendly, knowledgeable and clearly passionate. He did a great job of explaining the complex geology but also putting it in context of the people living near these areas in Iceland and how they live and are affected by the "dragon" beneath their feet. The bus was comfortable with plenty of rest stops and the day flew in! Great value for money for what you get to experience.”
