There are multiple styles of tourist activity. One of the most important of such styles is medical tourism, which represent a style distinct from the traditional patterns of tourism. There are many areas that have therapeutic natural resources, as Siwa Oasis is considered one of the most important oases that enjoy these features as will be clarified later from the research. The research aim is to increase the competitiveness of the medical tourism activity in Siwa Oasis due to the lack of optimal exploitation of the resources available in the oasis. The study analysis the spaces in the used case studied based on comparative analysis method. However, the importance of medical tourism in Egypt, particularly the Siwa Oasis, it is found from the comparison between selected cases, there is an insufficient demand by tourists in Siwa, an absence of medical buildings inside the resorts compared to resorts outside Egypt, the lack of sufficient exploitation of the oasis's resources, and an obvious separation between the main clusters of resorts in Siwa.
