See the Northern Lights
On clear nights, there is also a good chance of witnessing the Northern Lights - the extraordinary natural light show that occurs when charged particles from space enter the Earth's atmosphere, creating shimmering bands of colour across the night sky.
Stay a Night at the Ice Hotel
Combine the dog-sledding with a night at the world-famous Ice Hotel in nearby Jukkasjärvi. Rebuilt each year using 30,000 tons of snow and 4,000 tons of ice from the Torne River, the hotel melts away each spring to become part of the river again. A night in this cathedral-like igloo is a great experience, sleeping in special thermal sleeping bags on beds of ice, covered with reindeer hides.
Activities at the Ice Hotel include ice-sculpting, snow-shoeing, ice-fishing and snowmobile safaris in search of the king of the forest - the elk (moose). There's also the chance to learn a bit about the local Sami people, and their traditional way of life in harmony with animals and nature.
On the way home, stop off in Stockholm for a day or two and explore this beautiful city.
