Sha'ab Rumi & Cousteau's Underwater Village: A Diving Guide

About 35 kilometers northeast of Port Sudan lies one of the strangest dive sites on Earth: Sha'ab Rumi, the reef where Captain Jacques-Yves Cousteau ran the most famous underwater living experiment in history back in 1963. Today, the silent remains of "Cousteau's underwater village" still welcome divers, and schools of hammerhead sharks still patrol its deep blue drop-offs. If you want a dive that mixes history, adventure, and dense marine life, Sha'ab Rumi is Sudan's must-dive site.

The 1963 Cousteau Experiment: Conshelf II

In the early 1960s Cousteau and his team were chasing a bold question: could humans live and work underwater for extended periods? To answer it, they built Conshelf II on the edge of Sha'ab Rumi — a starfish-shaped steel habitat where five "oceanauts" lived for a full month at around 10 meters depth, supported by a deeper submerged garage for Cousteau's famous diving saucer.

Cousteau filmed the project in "World Without Sun," which won an Academy Award and put Sha'ab Rumi permanently on the global diving map. The site was chosen carefully: clear water, a dramatic reef wall, and currents that bring in big pelagic life — the same reasons it remains an exceptional dive today.

What Remains of the Underwater Village?

Most of the large structures were removed after the experiment to protect navigation, but divers can still see:

• Cage frames and small experiment fixtures now encrusted with coral, fused into the reef itself.
• Remains of the saucer garage and old pipe and cable runs across the seabed.
• Kitchen tools and metal hardware that have become artificial mini-reefs swarming with small fish.

The scene is genuinely surreal: objects of everyday human life resting quietly among corals, as if time stopped in 1963. Many divers describe a Rumi dive as visiting an underwater museum rather than an ordinary reef dive.

Hammerhead Sharks and Marine Life

The outer wall of Sha'ab Rumi is one of the Red Sea's best-known hammerhead shark sites. In season, schools of scalloped hammerheads gather in the deep blue at dawn, while grey reef and silky sharks cruise the shallower water. On top of that you'll find:

• Huge schools of barracuda, jacks, and large groupers.
• Hawksbill and green turtles grazing on the coral plateaus.
• Giant gorgonian fans and rare soft corals along the edge.

Visibility frequently exceeds 30 meters in season, and the shallow plateaus are excellent for photography.

Required Diving Level

Sha'ab Rumi suits several levels. The shallow plateaus and the village area (10–18 meters) work well for Open Water certified divers with a guide. Hunting for hammerheads in the blue, however, demands an Advanced certification and a solid logbook — descents can pass 30 meters and currents are common. On our trips, each group dives with a guide who knows the site and its currents, and we plan profiles around the group's experience.

Best Seasons to Visit Rumi

Diving Sha'ab Rumi is possible most of the year, but the seasons differ:

• October to January: the famous hammerhead season, cooler water, superb visibility.
• February to May: warm, calm seas — ideal for photography and long plateau dives.
• Summer: hot topside, but active marine life and fewer boats.

Combining Rumi with Irg and Arkaweet

Because Sha'ab Rumi sits on the northern site line, Blue Shark runs trips that combine it with nearby reefs that are just as stunning: Sha'ab Irg, known for its coral towers, and Arkaweet, with soft corals and occasional manta rays. Details of the Rumi trip itself are on the Sha'ab Rumi trip page. That gives you three varied dives in a single day or short trip — something expensive liveaboards rarely match for value.

Practical Tips Before Your Rumi Trip

Because the site sits in open water and is affected by current, we recommend the following:

• Bring your certification card and logbook — the guide will ask about them before planning the deep dive.
• Pack a dive computer, surface whistle, and a surface marker buoy (SMB); we rent all of these if you don't own them.
• Take sunscreen and a hat for the surface interval, plus light dry clothes for after the dive.
• Stick to the agreed dive plan and depth limits; the site's magic lies in diving it wisely, not riskily.

The village remains are fragile and reef protection rules prohibit touching or taking anything. The rule is simple: capture with your eyes and camera, and leave everything in place for those who come after you.

FAQ About Sha'ab Rumi

What is the story of Cousteau's underwater village?

It is the remains of the Conshelf II experiment Cousteau ran in 1963, where five divers lived for a month in a submerged steel habitat at 10 meters. The Oscar-winning film documented it, and some structures and tools are still visible to divers today.

Is Sha'ab Rumi suitable for new divers?

The shallow areas and village site suit Open Water divers with a guide. Seeing hammerheads in the deep requires Advanced certification and comfort with currents. We always organize groups by level.

When do hammerhead sharks appear?

The best chances are October to January, early morning at the outer wall. Sightings are never guaranteed — these are wild animals following currents and food.

How long is the trip from Port Sudan?

Roughly one to one and a half hours by boat depending on sea conditions, and trips usually include two or three dives with surface intervals on board.

Sha'ab Rumi is not just another reef; it is a piece of world diving history lying an hour from Port Sudan's harbor. Book your seat on our next trip through our contact page and we'll arrange a dive you won't forget.
