Since the dawn of human culture in Africa and the Middle East, the Sinai and Red Sea region has been an important crossroads-then a land bridge, now a sea bridge-connecting East and West, North and South. Enormous container ships and fancy ocean liners line up to pass through the Suez Canal. Canal towns such as Ismailiya and Bur Sa'id (Port Said) make interesting day trips from Cairo, if you have the time. But the novelty of passing ships can wear off rather quickly, leaving little else to do.
Not so the Sinai Peninsula and the Red Sea Coast, where relaxing on the beach, trekking through the desert, and diving amidst a wealth of marine life are probably the opposite of what you'd expect from a trip to Egypt. The desert itself, inland Sinai, has changed little since the times when Bedouins moved from one watering hole to the next. It remains awe inspiring, especially if you get up for sunrise and catch the mountains changing from purple to red, then orange to yellow.
The Red Sea continues to be an underwater haven, a living aquarium, in spite of the impact that a rush of divers has had on the reefs. Since the mid-1990s this coastline has undergone a multimillion-dollar makeover and has been transformed into the so-called Red Sea Riviera and marketed successfully to vacationers across northern Europe and the newly emerging countries of the old Soviet bloc. If you want resort amenities and the option of escaping to virgin desert spotted with shady acacia trees and lazy camels, this is the place for you. If you want to see ancient monasteries and biblical sites, or follow Moses' path from Egypt to Jordan, you can do that here, too.
Although Egypt is conservative when it comes to everyday attire, guests in the resort areas of the Sinai and the Red Sea often walk around in shorts and tank tops. Some people choose to dress up for dinner, although it is not mandatory. If you plan to visit any of the monasteries, dress modestly. The Suez is not a resort area, so don't walk around in shorts, women especially; long, loose clothing is a better idea. If you are driving around the area, and definitely if you are taking buses, wear long pants and short sleeves (nothing sleeveless).
