Hvalfjörður is a beautiful and tranquil 30 kilometre long fjord. It was once an excellent harbour and a naval base during the Second World War. At one time, anyone traveling from Reykjavik up north has to drive the length of the fjord. In 1998, the most ambitious tunnel construction in Iceland was finished, and today Hvalfjörður is a desolate, quiet fjord well worth driving by for those with enough time. In the bottom of the fjord is the impressive Glymur, Iceland’s highest waterfall with a drop of 198 meters.
