My wife and I made our way around the entire island while we were in Iceland and stopped at Lake Myvatn on our way through the north. It was a really beautiful lake, but I don’t know that I would recommend coming through the north unless you just have a TON of time in the country. It was a lot of driving and there are WAY more things to see on the south and west part of the island.
