Hop on a small group tour with a personal service that takes you along the route of Goðafoss waterfall, Lake Mývatn, Dimmuborgir Lavafield, Námafjall geothermal, Psudocraters and the Grjótagjá Cave. If we have time, depending on cruise ships departure time, we visit the Mývatn Nature Baths, where you will get an opportunity to dip into the geothermal water (note that the entry fee, a swimming suit and a towel is not included) or enjoy some refreshments at the inhouse café with a scenic view.
