We had a fabulous all-day tour with Mark. The communication was excellent and Mark shared his enthusiasm and vast knowledge of Orkney with us. He made sure we comfortable throughout the day and that we got to see the highlights of Orkney that we wanted to see. Mark was a pleasure to be with for the day! We are so glad we booked this tour and highly recommend it to anyone wishing to know about the history and the way of life in beautiful Orkney. Erna
