Diving the Sunken Ruins of Cleopatra's Palace, Eastern Harbour

Diving the sunken ruins of Cleopatra's Palace explores the submerged remains of the royal quarter believed to have stood on Antirhodos Island in Alexandria's Eastern Harbour, Egypt, before earthquakes and rising sea levels pulled the site underwater roughly 1,500 years ago. The dive passes over scattered column drums, paving stones, sphinx fragments and masonry blocks that archaeologists associate with the Ptolemaic royal palace complex, reached by a short boat ride from the Corniche harbour front. This is a certified-diver activity: participants must hold a valid open-water certification and logbook, and operators generally expect divers to be comfortable with boat entries, mild current and depths in the 5-8 metre range typical of harbour diving. Full scuba kit, including tank, regulator, buoyancy control device and weights, is available for rental from Alexandria dive centers such as Alexandra Dive and other licensed operators in the city; divers need only bring their certification card, swimwear and, if they own one, a personal mask and fins for comfort. Reputable centers run a pre-dive briefing covering the harbour's boat traffic, entry and exit procedure from the dive boat, buddy checks, and an evacuation plan that returns divers to the support boat or a fixed mooring point if conditions change mid-dive. Because the Eastern Harbour remains a working waterway, operators monitor sea state and shipping activity closely and will delay or relocate dives when swell, poor visibility or vessel movement make the site unsafe. The best diving season runs April through October, when the Mediterranean is calmest and underwater visibility is at its clearest; winter months bring rougher seas and reduced clarity that make the ruins harder to see and the boat transfer less comfortable.
