This article focuses on presenting a proposal for ecotourism services on a green university campus based on the process of design thinking by students. Participatory action research, co-creation and psychosocial intervention methodologies were considered to develop this process. This study established the following two important results: on one hand, a green campus initial intervention proposal emerged, which included a service description and special features; on the other hand, as an additional result, a series of overall observations and suggestions provided by students around the field and its surrounding facilities emerged. Finally, it is concluded that there is great potential for ecotourism in green campuses as a training and tourist process. 2023 Inderscience Enterprises Ltd.
