Dahrat Ghab is located on the western edge of the South Sawakin Group, approximately 24 nautical miles from the mainland coast. The elongated island is oriented in a west-east direction.
Like many islands south of Port Sudan, it is overgrown with green shrubbery. The seabed reaches depths of over 500 meters in the surrounding area. There is a large plateau on the east side. There is a small heel around the entire island at a depth of 3 meters. An extremely lush and colorful underwater fauna and flora flourish at this dive site. Experienced Sudan divers consider this island the most beautiful dive site in the entire Red Sea.
From a depth of 3 meters, the jagged reef wall falls steeply into the deep blue. Snorkelers also get their money's worth. There is a lot to discover in the numerous small crevices and caves. The spines of sea urchins protrude from small holes. Couples of masked butterflyfish stand under the ledges. Spotted hedgehog fish, like the flute fish that usually swim below the water surface, move along the reef. The entire outer wall is beautifully overgrown with stone and soft corals. Small calyx corals have settled on the hard underground, as well as magnificent anemones and large fan corals. Different sponges give the reef wall a colorful look. Below 25 meters, the outer wall drops steeply to great depths, where the realm of deep-sea fish begins.
There is a steep slope below the heel. At 26 meters from the base of the plateau, it flows into a transverse channel. The slope is overgrown with stone and soft corals. Countless small, colorful reef inhabitants swim between them, such as tobacco butterfly fish, groups of Eurasian weaver fish and red sea anemone fish. In the canal, the north current that occurs most often can become so strong that it is hardly possible to "swim against". There is often a large group of buffalo-headed parrotfish. Large groupers and sometimes manta rays can also be found The bottom of the canal initially rises again to 22 meters and then drops steeply to a depth of about 60 meters from the plateau. Various shark species and pelagic schooling fish such as prickly mackerel and tuna can be observed.
- Depending on the season, there are good chances to encounter different shark species, manta rays and large sea turtles.
