A sustainable city is one that meets the needs of the current population without undermining the ability of the future generations to meet their own needs. The current research aims to study the ability of applying the model of a sustainable city to Marsa Alam. The research investigates the adoption of a new method in the construction of cities by relying on environmentally friendly systems. It also examines the importance of transforming the traditional tourist destinations into sustainable tourist cities. This research used the descriptive-analytical approach, where a questionnaire was prepared and distributed to a random sample of 106 of researchers of the Egyptian Environmental Affairs Agency (EEAA) in the Red Sea Governorate, the employees and decision makers of the General Administration of Environmental Affairs in the Red Sea General Office in addition to other academic researchers. The data were analyzed using descriptive statistics, Pearson correlation analysis, and regression analysis in SPSS 22.0. These analyses result in a moderately positive and significant relationship between the possibility of applying the sustainable cities model to the city of Marsa Alam and the benefits that will accrue to Marsa Alam after it transforms into a sustainable city. As a result, this research recommends paying attention to Marsa Alam from the perspective of sustainability as a worthy coastal destination in Egypt.
