You're never going to catch us praising Iceland for its cheap and efficient public transportation. Without your own car, getting around the island is prohibitively costly and inconvenient. But as far as day trips from Reykjavík go, an excursion to the Westman Islands is about as simple as it gets.
Just a few miles off the southern coast of Iceland are the Westman Islands (Vestmannæyjar). Though the archipelago consists of over a dozen islands, only Heimaey is large enough to support a community. With beautiful nature, relatively mild weather and an exciting history, the Westmans have long been a popular spot for day-tripping Icelanders.
The Hornstrandir Nature Reserve, in the northwestern corner of Iceland, has been almost completely spared from the corrupting fingertips of mankind. No roads scar the landscape and there are no permanent residents, unless you count the arctic foxes which abound in its hills. We spent a long day exploring a small section of the reserve.
