From its snow-capped mountains to its mighty fjords, from grand valleys to tranquil lakes and lovely archipelagos, the county of Troms is bursting with natural wonders. To cap it off, it also plays host to the northern lights. Tromso, the capital, is the gateway to the region's rugged beauty, but with 65,000 people it's also a surprisingly rich city culturally, with many interesting museums and sites (including the world's northernmost botanical garden) and even a pulsing nightlife.
