Sweden is a land of incredible contrast. Home to a vast array of landscapes - from the dense pine forests and craggy mountains of the north, to the rolling hills and glossy golden beaches of the south - the gap widens even more when you take the country's urban centres (home to 84% of the population) into account. The seven major cities, which include Malmo, Gothenburg and the capital, Stockholm - each have their own distinct character, compelling histories and wildly varying architectural styles. Despite these differences, urban Sweden tends to be stylish, modern and sophisticated, while the countryside offers simpler pleasures for those in search of peace and tranquility. Much of Sweden is forested, and there are thousands of lakes, including the large stretches of water between Gothenburg and Stockholm. The border with Norway is home to the spectacular Skanderna (Scandinavian) mountain chain, while in the far north you'll find wonderfully bleak Arctic tundra - here it's possible to see the Northern Lights. Running through this remote part of Lapland, the long-distance trail of the Kungsleden or 'King's Trail' extends for 440 kilometres from Abisko in the north to Hemavan. The northern part of this maintained track runs as far as Kebnekaise and provides an excellent summer trekking route, as well as a classic hut-to-hut ski tour in the winter. In winter, Abisko is one of the best places in the world to see the Northern Lights.
