Situated on the tip of the Red Sea in southern Jordan on the Gulf of Aqaba, one of the town's prominent attraction lies offshore in the colourful coral reefs that are rated as some of the best in the world. These boast a vibrant marine life and provide several opportunities for divers and snorkellers in the clear waters year round. Besides underwater escapades, Aqaba is an ideal location for watersports and relaxation, whether it is swimming, waterskiing, parasailing, fishing or sunbathing. For the history enthusiast, Aqaba contains sites dating back to 4,000 BC, including the recent discovery of what is believed to be one of the world's oldest churches from the 3rd century AD, the remains of the medieval walled city of Ayla and a Mamluke fort. These are proof of Aqaba's strategic position as the main port on the trading route to the Far East from Africa in ancient times, which made it a thriving town, and it is this same location today that makes it an important tourist centre. It is also conveniently situated for excursions to the spectacular desert scenery of Wadi Rum and the ancient rose rock city of Petra.
