If you find yourself with a spare day or two and you don’t mind traveling 20 miles, check out Hveragerdi. This vibrant destination boasts lots of things to keep you entertained. Among your first stops here ought to be Reykjadalur Valley, Geothermal park and LA Art Museum. Locals will also probably point you toward Mosfellsbaer, 35 miles away. If you only have time for one attraction here, let it be Varmarlaug Swimming Pool. (But we’re also big fans of Alafoss Waterfall and Ulfarsfell Mountain.)
