Currently, Cox's Bazar from Bangladesh has been recognized as a rising tourism spot amongst the fastest-growing destinations in the world. Tourism in this area has led to the development of facilities such as hotels, restaurants, airports, souvenir shops, etc., and has supported local communities in the form of job opportunities. Recently, the region has shown signs of negative environmental impacts such as overcrowding, poor waste management, security concerns, and the creation of unplanned hotels to meet very high local tourism demand. The results of the study show that Bangladesh has great opportunity for its economy to thrive on tourism and that the internationally recognized legacy of Cox's Bazar has many tourism products to attract tourists from all over the world. However, due to a lack of resources and other reasons, government initiatives are not sufficient to develop tourism in the country. The author attempts to consider some areas that need immediate attention, based on the concept of sustainability. The study methodology is descriptive based on empirical data and a wide range of literature from various disciplines, and it concludes with recommendations that interventions are necessary to develop and modernize Cox's Bazar, including other potential tourism destinations in Bangladesh.
