Shaab El Erg - Manta Point
The name suggests that this is the place to go to if you want to see manta rays. Once upon a time this may have been true. The dive site is situated at the north tip of the reef system of El Erg where the northern current brings in nutrient water. So at the right time of year, (normally just after the first full moon following the equinox) there should be plankton enough for the mantas to feed on, but they are not here. Still, this is a nice dive site.
Here is a plateau that slopes from the reef at 9m to 12 meters down to the drop off at 25-30 meters. Depending on the current, you choose whether you want to start out west or east. Either way, it is basically the same dive. Keep in visual range of the reef and have a look at a few pinnacles on the way out. After turning around you explore the wall itself and the many pretty coral blocks next to it. Here you will find a very rich marine life with different kinds of rays, sole and eels and bigger fish like groupers.
If you swim back next to the top of the reef at around 5 meters you will find that this is the best part of the wall. Make a long safety stop and you will be rewarded with a spectacular scenario. This is a dive site that has a lot to offer but do not keep your hopes up for manta rays because then you will be disappointed.
