Dive Site: Plaza Islands

About Plaza Islands

Plaza Islands offers exceptional diving within Ecuador's Galápagos Marine Reserve, renowned for its abundant marine life and position in one of the world's most biodiverse ocean zones. This site attracts divers with its strong pelagic activity and the presence of species found nowhere else on Earth. While conditions vary seasonally, the site is accessible for diving throughout the year. The topography of the dive site is characterized by an active, nutrient-rich environment, drawing a wide array of marine creatures. Although specific depth profiles are not detailed in the sources, the Galápagos generally features deep waters around its volcanic islands, with the visible portions of volcanoes being just the surface of much larger underwater structures. The marine ecosystem here thrives, supporting species like hammerhead sharks, Galápagos sharks, sea lions, and various rays, alongside smaller reef fish and invertebrates. Whale sharks are seen from June to November, while large schools of hammerheads and giant manta rays are more prevalent from December to May. These seasonal shifts influence marine life behavior and sighting opportunities. From a practical diving perspective, Plaza Islands is best suited for intermediate divers due to potentially strong currents and varying conditions. While specific details on entry/exit are not provided, liveaboards and day boats typically facilitate access to Galápagos dive sites. Divers should expect cooler water temperatures during certain months, necessitating appropriate thermal protection.

Conditions & Currents

Diving in the Galápagos, including at Plaza Islands, typically involves medium to strong currents, requiring divers to be experienced or advanced. Currents can be influenced by trade winds and oceanic phenomena like the Humboldt and Panama currents, leading to varying strengths and directions throughout the year. Surge and eddies are common underwater, and occasional down-drafts can occur, adding to the challenging conditions. While specific current patterns for Plaza Islands are not detailed, the general Galápagos environment means divers should be prepared for drift diving and practice good buoyancy control. Visibility, though generally good, can fluctuate from 10 to 30 meters, sometimes decreasing in nutrient-rich upwellings, particularly during the cooler season. Divers must account for these variable conditions in their dive planning, including gas consumption and safety stops, and

Dive profile & how the dive runs

A typical dive at Plaza Islands focuses on exploring the rich marine environment that thrives due to upwellings and currents. Divers usually enter the water via tender from a liveaboard or day boat, often performing a negative entry to quickly descend and mitigate surface currents. The route typically follows the contours of the underwater landscape, allowing for observation of pelagic species in the open water and reef fish closer to the rocks. Depth progression can vary, but generally, divers will explore different depth bands to encounter a diverse range of marine life. Attention is often directed towards areas where currents are more pronounced, as these are hotbeds for larger marine animals. The turn point is determined by air consumption and bottom time, with divers often drifting along the current. Safety stops are conducted in shallower, more sheltered areas if available, or as a blue-water stop, requiring careful buoyancy control, especially with potentially strong currents. The dive concludes with an ascent back to the tender boat, which will follow the divers' drift.

Underwater photography

Plaza Islands offers excellent opportunities for wide-angle photography, especially for capturing the vibrant pelagic action and large marine animals. A fisheye or wide-angle lens (e.g., 10-17mm or 16-35mm equivalent) is recommended to frame schooling hammerheads, manta rays, and whale sharks against the blue water. External strobes are beneficial for adding color and detail, especially in deeper or less clear conditions, helping to cut through backscatter. When photographing larger subjects, ensure you maintain a respectful distance to avoid disturbing their natural behavior. For smaller reef fish and invertebrates, a macro lens might be suitable, though the primary draw of Plaza Islands is its big animal encounters. Buoyancy control is paramount, particularly with the prevalent currents, to avoid damaging the delicate ecosystem and to maintain stable shots. Natural light can be sufficient for wide shots in good visibility, but strobes will enhance color and contrast.

Getting there & logistics

Access to Plaza Islands in the Galápagos typically involves flights into the Galápagos Ecologic Airport (GPS) on Baltra Island, or potentially San Cristobal Airport (SCY). From these airports, liveaboards are the most common way to visit remote dive sites, offering itineraries ranging from 7 to 10 days. Some land-based island hopping tours also offer diving, often departing from Puerto Ayora on Santa Cruz Island. Divers need to budget for the Galápagos National Park entrance fee (currently $200 per person) and the INGALA tax ($20 per person), which are usually not included in tour prices. Dive equipment rentals are available, but many divers prefer to bring their own. Permitting and operator restrictions are strict due to the protected marine reserve status, so it's essential to confirm all requirements with your chosen operator before travel.

Safety & environment

Diving in the Galápagos demands a high level of preparedness. The nearest recompression chamber is located in Puerto Ayora, Santa Cruz Island, making immediate access a concern for serious dive emergencies. Evacuation from remote dive sites to the chamber can take several hours, often involving boat transfers. Therefore, comprehensive dive insurance, including coverage for emergency medical treatment and evacuation, is not just recommended but essential. Site-specific hazards at Plaza Islands include strong and unpredictable currents, potential down-currents, and varying visibility, which can pose challenges for less experienced divers. Proper training, including advanced open water certification and experience in current diving, is highly advisable. Divers must strictly adhere to guide instructions, maintain excellent buoyancy control, and always dive within their limits. Observing marine life from a respectful distance is crucial to protect both divers and the delicate ecosystem.
