The work consists of a theoretical and empirical part. The terminology of ecotourism was elaborated and the Prpic economy was explored. Therefore, the aim of this paper is to define the concept of ecotourism, to present the hard and soft features of ecotourism, the key characteristics and common characteristics of the ecotourist profile, to explain the historical development of ecotourism, the principles of ecotourism, the ecotourism principles and the characteristics of ecodestination, and finally to define ecological agriculture and to support its importance by research Croatia has great potential for the development of eco-tourism which needs to be adequately valorized and protected in accordance with the concept of sustainable development. Ecotourism is also mentioned as ecological awareness in tourist demand and tourist offer. That is why ecotourism is not just a term of ecologically sound tourism but also an effort to provide adequate protection of resources within tourism. Tourists need to socialize with locals, learning something about the history and nature of the area they are visiting, exchanging information and building communications that are constructive, educational and ethical, and not frustrating and frustrating for the local environment. Ecotourism can be developed within national parks and other protected areas, but also on family farms operating on the principles of ecological agricultural production. An ever greater attraction among ecotourists is ecologically produced foodstuffs and there is also an opportunity for family farms. Therefore, if Croatia wants to be a country with a recognizable ecotourism product, it must take a series of measures at state and local levels. It is necessary to implement more stringent environmental protection measures, introducing concrete measures to encourage eco-tourism development and various quality control of tourist supply.
