Shetland. The most northern Islands of Scotland.
I’ve been there in the 2014 Winter for the Up Helly Aa with my wife. We spent one week driving around the isles with a rented motorhome. Winter in the Shetland is stunning, strong winds, gales, battered cliffs. Weather is tough during this period but it can be a great experience if you like northern climate. Temperature are usually not so cold since the Gulf stream keep winter temperature usually above zero.
