Sports and recreation have become one of the main components of tourism. Even though summer tourism is the most significant in Croatia, winter tourism should not be neglected. Croatia has natural resources which can make winter time also interesting both for Croatian and foreign tourists. One of those resources is the Nature Park Medvednica. The Nature Park Medvednica is situated on a mountain close to Zagreb. The main reason for the park being a protected area is the big and dense forest. Each year Nature Park Medvednica visit about million visitors, and during winter the ski resort “Sljeme” becomes the main attraction which is situated in the highest peak of the park “Sljeme”. Issues which the ski resort “Sljeme” is facing are: a huge number of cars, high temperatures and the lack of cable cars which would be suitable for beginner skiers. Nevertheless, despite these disadvantages the ski resort is world–renown because of the major world competition “Snow queen”. Apart from skiing, the nature park offers other recreational activities such as hiking, biking, sledding, jogging and Nordic walking. The winter tourism offer is quite scarce in comparison with other ski resorts and it is precisely because of this reason that there is a lot of room for improvement.
