About Garajau Marine Reserve
Garajau Marine Reserve, situated along Madeira's southern coastline, is Portugal's flagship dive site and one of the most vital marine reserves in the Atlantic. This nationally protected area, established in 1986, is renowned for its exceptional marine biodiversity and clear Atlantic waters, making it a benchmark destination for underwater exploration. The reserve spans a dramatic stretch of volcanic walls, dropping from 5 to over 40 meters, adorned with colorful sponges and anemones. Fishing has been banned for decades, fostering a thriving ecosystem where marine life is abundant and notably unconcerned by divers. Divers frequently encounter large groupers, some weighing over 30 kg, which approach with curiosity. Moray eels peer from crevices, barracuda schools patrol the blue, and lucky divers might spot manta rays gliding overhead. The reserve also hosts tunas, stingrays, parrotfish, and trumpetfish. It offers a variety of iconic dive sites like T-Reef, Cape Garajau, and Pinacolo, providing diverse underwater landscapes suitable for different experience levels. The excellent conditions for underwater photography were recognized when the reserve hosted the European Championship of Underwater Photography in 2022. The average dive depth ranges from 15 to 20 meters across various sites, making it manageable for certified divers without advanced deep-water training. Waters around Madeira are generally calm, supporting access for all levels, with shallow areas for beginners and deeper walls for advanced divers. Access to the reserve is typically by boat from Funchal or Caniço.

Conditions & Currents
The waters on Madeira's south coast, including Garajau, are generally calm, providing relaxing dive conditions suitable for all levels. While currents are typically mild, some sites within the reserve can experience stronger flows, offering more challenging yet rewarding experiences for advanced divers. Visibility is consistently very good, often exceeding 30 meters. Thermoclines are generally absent, with water temperatures remaining between 18-24°C year-round.

Diving at Garajau often begins with a boat entry, typically just minutes from Funchal or Caniço. A popular route involves descending along a line from a buoy, about 50 meters from the main beach. Upon reaching 15 meters, you'll encounter large rocky boulders and sandy patches. The dive typically progresses along volcanic walls that drop from 5 to 40 meters, exploring crevices and overhangs where moray eels hide and sponges thrive. Schools of barracuda patrol the open water, while curious groupers often approach divers. You can continue along the reef, maintaining depths suitable for your certification, with the turn point usually determined by air consumption or bottom time. The safety stop is conducted in the shallower, protected areas of the reserve, often around 5 meters, before ascending back to the boat.
Underwater photography
Garajau Marine Reserve offers exceptional opportunities for underwater photography, particularly for wide-angle shots of its dramatic volcanic topography and macro photography of the diverse marine life. The consistently high visibility, often exceeding 30 meters, makes wide-angle lenses ideal for capturing the expansive walls, arches, and large groupers that are a hallmark of this site. For close-up encounters with moray eels, nudibranchs, and other macro subjects, a macro lens with appropriate strobes is recommended. When photographing the famously curious groupers, maintain calm movements and avoid any actions that could disturb them. Buoyancy control is paramount, especially when navigating around delicate sponges and anemones on the volcanic structures, ensuring you don't stir up sediment or damage the environment. Use external lighting to bring out the vibrant colors of sponges and fish against the clear Atlantic waters.

Safety & environment
Madeira is equipped with a hyperbaric chamber located in Funchal, providing essential support for dive emergencies. Divers should always ensure they have comprehensive dive insurance that covers emergency medical treatment and evacuation. Site-specific hazards at Garajau are generally low due to its protected and relatively calm nature, but divers should be mindful of volcanic rock formations and maintain excellent buoyancy control to avoid contact. Currents are typically mild but can occasionally be stronger, so divers should assess conditions with their dive guide. All diving in the marine reserve is regulated, with operators adhering to strict guidelines, including booking slots for limited boat access. Respecting marine life by not touching or disturbing it is a crucial conduct rule to preserve the delicate ecosystem.
