Welcome to our Adventure Club! We have got various programmes for you. You can choose to travel by boat along the river. If you are fond of hiking, we have different routes. You'll see the places which tourists rarely visit and take unique photos of them. You'll learn how to put on tents and provide first aid. You'll also learn to overcome difficulties and work as a team. During the winter holidays you can take part in an unusual tour and learn how to drive a sledge-dog team.
