I will echo what others have already stated: Iceland is very well suited for private touring, especially if you are going inland off of the main Ring Road.
We had one week in Iceland, and did the Glaciers and Waterfalls tour. Erling was very helpful and responded to my e-mails in a timely manner.
He took care of us and made all of the arrangements which was wonderful; all we had to do was show up and have fun!
For the 4 days spent outside of Reykjavik, our guide was Rakel and she was fantastic!
We saw all the major sites listed in the "Glaciers & Waterfalls" itinerary (Blue Lagoon, Golden Circle, the glacial lagoon), plus had many other special stops and activities (hiking, snowmobiling, horseback riding).
It truly was an incredible trip that we will not forget.
Thanks to Erling and Rakel for making it so fun and hassle free!
