Camping tourism has developed into a complex form of tourism, in which tourists particularly appreciate natural beauty, nature conservation and connection with nature. Today, the health of man and his environment is particularly important in all spheres of human activity, including tourism. Due to changes in the way of life and values in modern society, trends in tourist demand for camping tourism are also changing. Such trends have turned camping tourism into a more expensive way of spending a vacation in nature and modern campers are looking for more and more luxury and comfort during their vacation. Taking into account all of the above, the entrepreneur developed the idea of opening an eco-camp in the area of the Municipality of Funtana in the County of Istria. The County of Istria is a market-affirmed tourist destination, and the Municipality of Funtana is one of the most developed municipalities in terms of tourism, known as a quality camping destination. The entrepreneur owns his own land, and by realizing his entrepreneurial idea and opening an eco-camp, he wants to meet the needs of tourists, sustainability criteria, enrich the offer of Funtana and ensure a long-term source of income for the family business. The paper presents the entrepreneurial plan for opening a small eco camp. The plan is elaborated from the description of the entrepreneurial idea, to the technical-technological part, market analysis, marketing plan, financial analysis and final assessment.
