I flew in fairly early and knew I needed something to occupy my time to avoid continued jet lag. I explored Reykjavik in the morning on my own and went on this tour in the afternoon. It was de-lightful, relaxing, and so very informative. I did fall asleep a few times on the bus, but that’s only because it was such a chill, small bus. A great activity for your first day in Reykjavik.
