This dive site, MarMar, is a prominent reef within the Farasan Banks, located approximately 48 km from Allith in Saudi Arabia. It is renowned for its dramatic topography, especially the east side which features a substantial slope from 0 to 500 meters, carved with numerous caves and caverns, offering a unique underwater landscape. The northern plateau, famously known as 'the washing machine,' experiences intense currents, making it a challenging but rewarding drift dive. There's no specific historical account mentioned, but its local name suggests a long-standing reputation among local divers. Navigation involves understanding the current patterns, particularly on the north side, to safely explore its diverse features.
MarMar is a vibrant marine ecosystem teeming with a variety of marine life. Divers can expect to encounter large pelagic species such as majestic Manta rays, powerful white tip sharks, grey sharks, and even occasional hammerheads. The reef is also home to schooling barracuda, impressive groupers, and charming blue spotted rays. While not explicitly detailed, the presence of a healthy reef structure supporting such a diverse food chain implies a rich variety of corals and smaller reef fish, including colorful parrotfish, contributing to the overall biodiversity.
The best time to visit MarMar for optimal diving conditions is generally when the currents are manageable, though the northern plateau is consistently known for its strong 'washing machine' currents. Divers should be experienced with drift diving and strong current environments. For freedivers, the shallower sections and cave entrances could be suitable, provided they are skilled and aware of the variable current strengths. The site's highlights include thrilling encounters with large sharks and manta rays, exploring the extensive cave and cavern systems, and experiencing the exhilarating drift over the northern plateau. Always check local conditions and dive with experienced guides.
