The Five Sisters, a group of five coral atolls near Rabigh, are popular with divers, is renowned for its stunning biodiversity. While there are five atolls in total, three sites are recommended here.
These sites offer a range of depths, from 29m to 35m, and varying current strengths, making them suitable for a wide variety of diving and snorkelling levels. While you may experience a challenging section, they’re sure to reward those up for the adventure.
The atolls are characterised by their lush and vibrant coral reefs, with pinnacles full of luminescent hard and soft coral heads creating a breath-taking terrain that is home to a wide variety of marine life. The reason so many creatures – from the simple tuna to the majestic silky shark – call this location home is because the National Center of Wildlife has declared the Five Sisters marine reserves in recognition of the importance of reef health to the surrounding natural ecosystems.
The first site is suitable for all diving levels and has divers start at the south corner of the main reef, north of the lighthouse. The stunning visibility of 60m means a clear view of the colourful wire coral as you descend the reef wall to a sandy bottom full of gorgonias.
Site 2 is a little more demanding, and only technical and advanced divers should attempt it. The dive ends on a plateau on the south side, offering a nice swim-through opportunity. The third site, beginning on the reef’s northeast side, is suitable for all levels except snorkellers. However, divers should still be cautious. Although the current is mild, the depth reaches up to 35m, and the route drops and twists between plateaus and pinnacles. Along with stunning coral formations and sweetlips, this site is known for its black dot snappers, a type of fish bearing distinctive black spots that is able to change colour to match its surroundings.
Different species of coral grow at different rates depending on water salinity, temperature and availability of food. Some branching corals grow as much as 10cm per year.
