The Mariout region possesses tourism potential in terms of cultural, historical, and natural attractions, making it one of the best areas for tourism investment in Egypt. However, the tourism environment in this region is threatened by environmental pollution problems. Consequently, these issues can deplete both natural and non-natural resources, potentially leading to a loss of tourism investment opportunities, particularly around Lake Mariout. This lake is considered a premier tourist destination for those seeking tranquility and fishing, but its tourism environment is now at risk, which can negatively impact the overall economy of the region. Based on these factors, this research sheds light on studying the relationship between environmental practices in the Mariout region and the satisfaction level with touristic services. Using a quantitative questionnaire, valid responses were obtained from 211 visitors to this area and 63 tourism experts. The results demonstrate that adherence to specific regulations regarding the management of tourism resources is positively associated with the satisfaction level with touristic services. Following that, social practices applied to tourism resources, such as environmental practices regulating the exploitation of the area, ranked as the most influential in relation to satisfaction levels. The research provides valuable insights for practitioners and stakeholders involved in tourism activities in this region. For example, it emphasizes the necessity of developing an integrated plan to halt all forms of agricultural, urban, and industrial expansion. Additionally, increasing signage to raise tourists' compliance with mandatory regulations when visiting tourist sites and implementing a strict punitive system for those who violate the laws governing tourism operations in the region are also crucial.
