Lots of attractions are open all year, including the Loch Ness Centre and Exhibition, Edinburgh Castle, Stirling Castle and Dunnottar Castle.
Hogmanay is the Scottish new year celebration. Traditions vary a bit in different parts of Scotland, but it usually includes gift-giving and visiting friends and neighbours. First-footing is a big part of Hogmanay - the first visitor to a house in the new year brings gifts of salt, coal, shortbread, whisky and fruit cake to bring luck to the house. The first-foot sets the luck for the rest of the year.
Hogmanay is also an excuse for a huge party, often continuing on for a couple of days. Edinburgh's Hogmanay is the biggest of these with organised street parties and fireworks.
There are Christmas Markets in towns and cities across the country. Edinburgh has the biggest, but the others are definitely worth visiting. Winter festivals also take place across Scotland, including some incredible winter fire festivals.
Scotland has five ski resorts, but it's not the Alps and the snow is sometimes unreliable. The best snow is usually in February and when the conditions are good, the skiing and snowboarding can be incredible.
