Firstly, the city itself is relatively compact and can easily be explored on foot or by bicycle. Most of the major attractions such as Naama Bay and the Old Market are within walking distance of each other. Additionally, Sharm El Sheikh has a well-developed public transportation system that includes buses and taxis. Buses are inexpensive and can take you to various parts of the city; however, they may not always run on time. Taxis are more convenient but can be quite expensive for long distances.
However, if you plan to venture beyond the city limits to explore nearby attractions such as Ras Mohammed National Park or Dahab, having a car would provide greater freedom and flexibility.
