This guy was great. Seriously, a knowledgeable, engaging, and unique guide. I and my two daughters (18 and 16) booked the Reykjavik tour with Sam. We spent about five hours with Sam the day we arrived. We actually were pretty tired after arriving at 6:30 am that day then spending then morning at the Blue Lagoon on the way into RVK so none of us were initially feeling like a walking city tour in the afternoon. Boy were we wrong. The time flew by. We not only learned a great deal about the history or culture of RVK and Iceland, Sam also provided lots of insights and observations about the Icelandic people and current society. The tour exceeded our expectations in every way and really set the tone for the rest of the trip, I would highly recommend doing this tour first thing because it really gives you a solid knowledge base that you cannot get from the guidebooks and websites, as well as a current frame of reference for your trip. Thanks Sam - you're the man in Iceland.
