A key resource or the attraction factor of insular tourist destinations are the beaches, natural and well-arranged. As a part of the coastal area, beaches are the basis of competitive advantage, the income generator within the tourist destination, and a component of the integral tourist product of an island’s destination. It is a highly valuable resource from the aspect of natural, social, economic and recreational potential. Numerous studies show that tourists choose insular and coastal Adriatic destinations precisely for enjoying the sea and sun on the beaches, i.e. the beauty of the landscape (Tomas, 2015). However, the same research also points to the dissatisfaction among beach users, especially when it comes to sports and entertainment. Insular tourist destinations whose main resource are the beaches, which have their ecological, recreational, social and other constraints, and which is highly sensitive in respect to reception capacity, are facing a major challenge to respond to the increased demand. This paper deals with the question of how to successfully manage the beaches of the island of Krk within the scope of the beaches' reception capacities and thus satisfy the needs of the users and prevent any unwanted consequences in the form of general dissatisfaction of tourists and other visitors. This paper gives an insight into the island of Krk, its problems and an approach to beach management. Many studies have also shown a discrepancy between accommodation and recreational capacities within tourist destinations and the beaches' reception capacities (Birkić, 2016). Considering the planned accommodation capacity building and the increased number of tourists, their interrelation is expected to get even worse.
