Blocks from the Pharos litter the sea bed near Fort Qaitbey, with Roman trading vessels lying 500m offshore (see The Pharos), while the ruins of Cleopatra’s Palace can be dived near Silsilah. Both these sites are only 5–8m underwater, so even uncertified divers may be accepted if they can pass a try-out. Diving in Abu Qir Bay requires more open-water experience, whether you’re exploring Napoleonic wrecks, or the ruins of ancient Herakleion. Still more experience is required on three-day wreck-diving safaris along the coast as far west as Mersa Matrouh that explore sunken German U-boats and Allied cargo ships. For all these excursions you must supply your passport details up to four days ahead. Images of ancient ruins and wrecks around Alexandria can be seen on w cealex.org under “Excavations”.
