With some terrific road trip options available in the surrounding area, renting a car makes good sense. Without one, it wouldn’t be half as easy to experience everything that Mosfellsbaer, 40 miles away, has to offer. Among your first stops here should be Varmarlaug Swimming Pool, Alafoss Waterfall and Ulfarsfell Mountain. Located 45 miles away, Reykjavik is another popular choice. If you visit, make sure you check out Reykjavik Harbour, Laugavegur and Viking Village.
