Supply chains are an integral part of the business of all types of companies, and their complexity is particularly evident in the business of tourism companies, where the supply chains of tangible and intangible products are intertwined. For this reason, the key differences in the functioning of supply chains of material versus non-material products are emphasized in the thesis. In order to illustrate the functioning of the supply chains of tourist companies, the example of Aquatika, as a relatively new anthropogenic tourist attraction in the city of Karlovac, was taken for the purposes of the thesis. In the business of Aquatika, the processes of sales, procurement and production are particulary emphasized. In order to gain a more complete insight into the functioning of supply chains in this company, research was conducted through interviews with the competent person in Aquatica, as well as research through a questionnaire with visitors of Aquatika. Through the analysis of the research results, certain deficiencies and areas for improvement were identified in the functioning of the supply chains, specifically related to the flows of people and marketing activities. However, examples of good business and the operation of supply chains are also highlighted, such as choosing local suppliers in the procurement process, introduction a circular layout to reduce the capacity load available when providing the service, and the extremely well-rated kindness and helpfulness of the staff.
