Port Sudan
Port Sudan is Sudan's main port city (population 500,000), the capital of the Red Sea State and the country's only major maritime gateway — all of Sudan's seaborne exports (cotton, sesame, peanuts, livestock and gold) and imports pass through this city on the western shore of the Red Sea, 850 km northeast of the capital Khartoum. The city was founded by the British in 1905 to replace Suakin (the historic Ottoman port city 60 km south, whose remarkable 19th-century coral-built buildings are among the most unusual architectural ruins in the world) and was designed as a modern deep-water port able to handle steamships that the shallow Suakin harbour could not. The Red Sea coast of Sudan is one of the world's most extraordinary and least-visited diving destinations — the waters from Dungunab Bay (north) to Shaab Rumi (the 'Roman Reef', where Jacques Cousteau conducted his 1963 'Continental Shelf Station' experiment, the world's first underwater living habitat) to the Sanganeb Atoll (an offshore reef rising from 800 m depth to the surface, one of the most biodiverse reef systems in the world) have exceptional visibility (40+ m), large pelagic fish (hammerhead sharks in schools, grey reef sharks, whale sharks, manta rays, Napoleon wrasse over 2 m) and pristine coral due to the extreme isolation that has kept human fishing pressure minimal. The city itself has the Othman Digna Museum, the old Ottoman-era coral buildings, the fish market and the lively Red Sea souk — but Port Sudan is primarily a gateway city for the extraordinary underwater world offshore. Note: As of 2026, Sudan has been in a devastating civil war since April 2023; travel to Sudan including Port Sudan requires urgent assessment of current conditions before any visit.
