We spent time in Sharm el Sheikh and found a great seafood restaurant in the bazaar in the old town.
Highlights for us - Mt Sinai at sunrise, day trip to Petra (AMAZING!!!!).
We went to Cairo for the day to do the essential pyramids and museum and couldn't wait to get out of there.
Sharm el Sheikh is a good starting point for diving. Lots of dive companies and good to get one that will take you further out ie, live aboard for a few nights.
I've heard Dahab is good for diving also. about 9 years ago
Here's the best diving site ever....The BLUE HOLE in Dahab, Sinai, Dahab is known to be enjoyable for backpackers..there's an underworld to discover over there. Also Sharm El Sheikh is amazing with incredible nightlife and five star hotels.
11 Days you can do many things. Start it off with Cairo for 1-2 day: Pyramids of Giza, Cairo Museum, and Tour in Islamic Cairo in el Hussein and Shop in Khan el Khalili (the oldest market museum and live bazzar)
You can then travel to Sharm for 3-4 days in a fancy hotel and go to boat diving trips to Tiran Island and Ras Muhammed areas, go to Mt Sinai tours..etc
remaining days you can take an extraordinary NILE CRUISE from LUXOR (the biggets OUTDOOR MUSEUM OF ALL TIME) to Aswan the most wonderful NATURE on the NILE of Egypt and Nubian villages and life to explore... almost 7 years ago
