This was a fabulous excursion. We loved the Blue Lagoon and the bridge between the continents. Stefan did a great job of adjusting the tour to accommodate some of my orthopedic issues that limited my walking. He also adjusted the tour to accommodate our request to have a nice sit down lunch. He was very knowledgeable and informative. We learned a lot about the geology and history of Iceland and about the areas forced to evacuate because of volcanoes and earthquakes. Stefan was a much better guide than other guides that we had on our excursions through the cruise line. He was very attentive to our requests and our needs. He also was very responsive to all of the emails that we sent him in advance with numerous questions. We highly recommend this excursion and using Stefan for any excursions.
