This was a great tour which I did not put much effort in but got a rather fantastic experience. Guide to Iceland had well arranged this trip. It showed me an overview of Icelandic landscape, including beach with black gravels, ocean with sapphire-color water, plain with lava and mosses, cliffs with running waterfalls, glaciers and icebergs, and hot spring lagoon covered by vapour. With the experienced guides, I learnt a lot about geology and glaciers, and also the culture of Iceland.
However, I have to say it was a quite intensive schedule and therefore I could not really spend a day in Reykjavik to know better the country. It was a bit pitiful that there was a mistake in booking my flight to Kulusuk in Greenland, but this was not the fault of Guide to Iceland.
Overall, this was a great trip and the staff of Guide to Iceland were really nice. The small gift was of great help. Next time I am in Iceland, I would still choose this guide.
