Sha'ab Mahmud is a large lagoon about 10 meters deep, closed at the western side by a very interesting long coral reef.
The lagoon interior is a very good mooring and safari boats often spend the night here. Usually the anchor is thrown on the sandy bottom of the lagoon, close to a break in the reef, the Small Passage.
This break, that can be crossed only by a zodiak, offers the perfect occasion to visit the wonderful reef outside the lagoon.
Depending on tides, the current can flow into or out of the lagoon. The best condition is when the current flows into the lagoon, thus giving the opportunity to dive along the reef and then enter the Small Passage and be pushed towards our mooring by the current.
During this dive turtles may be encountered. Moreover, one encounters certainly trevally and barracuda.
- As part of the Safari also Beacon Rock is visited. This reef is located at the southernmost point of the vast coral reefs of Shaab Mahmoud.
- In an unhappy night of the year 1876, the cargo ship Dunraven who was traveling from Bombay to Newcastle, hit the reef. After the massive collision, the ship sank immediately and broke into two large parts, which are today on the reef Beacon Rock in 18 and 28 meters depth
