Intact nature is by far Finland's greatest wealth. Huge natural parks form a whole network of thick forests, towering peaks, hundreds of thousands of lakes, plains and valleys, which tempt everyone who loves swimming, fishing, hunting, cycling, rock climbing, camping, kayaking. In the winter the northernmost area of Lapland and its main city Rovaniemi turns into the center point of major Christmas festivities but it is also loved for the magnificent northern lights and the great opportunities for North walking. In the summer the big cities such as Helsinki, Oulu, Turku, and Tampere host plenty of art and music festivals. The country is very appealing to travelers interested in religion and history, architecture and art with its churches and galleries, castles and museums. As a direct consequence of Finland's nature the types of accommodation vary a lot. The countryside offers a lot of chalets, mountain huts, camp sites and caravan parks. Guest houses and bed & breakfast are a good alternative of hotels in Finland but are rare. Hotels on their part are located mainly in the large cities and tend to be a bit expensive, opposite to hostels in Finland, which are many and inexpensive.
