The land of the Sinai is the "great and terrible wilderness" of the Bible, across which the Israelites journeyed in search of the Promised Land. Sharm-el-Sheikh serves as starting point for an excursion into the desert and to St. Catherine’s Monastery, the oldest Christian monastery in the world. St. Catherine’s Mountain is at 7,926 feet the highest summit in Sinai, followed by Mount Sinai, where God is said to have given the Ten Commandments to Moses. The most popular pastime in Sharm-el-Sheikh as well as in Na'ama Bay is exploring the underwater marine life. The reefs are easily accessible; diving and snorkeling equipment can be rented at watersports centers and dive shops. Glass bottom boat cruises are also popular to see the colorful underwater world. The main shopping areas are at the resort area of Na'ama Bay, located five miles from the port. Egyptian cotton, Pharaonic souvenirs and gold cartouches are popular. There are plenty of eateries at Na'ama Bay, and the hotels offer a variety of restaurants with everything from seafood to international cuisine and fast food.
