Much of Finland is pristine and virgin as it contains 35 national parks from the Southern shores of the Gulf of Finland to the high fells of Lapland. It is also an urbanised region with many cultural events and activities. Above the Arctic Circle, there is a polar night, a period when the sun doesn’t rise for days or weeks, or even months. Lapland, the extreme north of Finland, is so far north that the Aurora Borealis, atmospheric fluorescence, is seen regularly in winter. Outdoor activities range from Nordic skiing, golf, fishing, yachting, lake cruises, hiking, kayaking among many others. At Finland’s northernmost point, in the heart of summer, the Sun does not completely set for 73 consecutive days. Wildlife is abundant in Finland. Bird-watching is popular for those fond of flying fauna, however hunting is also popular. Elk, reindeer and hare are all common game in Finland. Olavinlinna in Savonlinna hosts the annual Savonlinna Opera Festival.
