I have worked with local guides many times on most continents, Halldor is an exceptionally excellent, personable guide. His English is idiomatic, so briefings and discussions are easy to understand. He arrived at the meeting location a little early, so perfect. We had previously agreed on visit sights for a walking tour followed by a driving tour. His vehicle was in excellent condition, matching as advertised. As he understood my interests more clearly, we mutually agreed to adjust a few tour stops. He is perfectly knowledgeable regarding history, culture and current events, able to answer all my questions except for a few esoteric topics. Halldor has my highest possible recommendation. I will happily engage with him as guide on my next Iceland visit.
