Herdis provided the platform for a quality field trip to Iceland. As a group of 16 University students studying Environmental Policy, she was able to tailor the tour to suit our interests whilst providing a balance of Icelandic culture past and present. Her knowledge on environmental issues and the choice of activities/sights were second-to-none. I would recommend Understand Iceland to anybody planning on visiting Iceland, especially those with a fascination of the natural environment. Herdis is lovely and approachable, whilst able to keep large groups on schedule. Her Father is also an absolute gem, providing quality anecdotes in-between stops. Will definitely use this group again.
