This is not the place to come if you're seeking ancient history. But if you stay in Sharm, Hurghada or El-Gouna, it's possible to enjoy day and overnight trips to Luxor (Thebes), Cairo or the temples of Abu Simbel overland or by air.
The only real point of interest on the Sinai coast is the Coloured Canyon, named after its technicolour rocks, and St Catherine's Monastery. Tours can be arranged to climb the peak above the building, Mount Moses, in time to see the sunset but the route is arduous and can get crowded.
You can't go on holiday to the Red Sea without catching a glimpse of its underwater treasures - from most resorts, dozens of boats offer snorkelling and diving trips out to the reefs and world-famous marine parks. The day-long cruises are packed and typically involve an early start. In peak season, divers can expect to be fighting for space on some coral reefs, which can be frustrating.
Day trips to islands are also possible. From El-Gouna, boats depart for uninhabited Gobal Island, where you can swim and snorkel to your heart's content in uncrowded waters, or sunbathe on deserted beaches and coves.
