Río Santiago
Why dive here
With 33+ marine species recorded in the area - including sperm whales - Río Santiago offers some of Mar del Plata's richest wreck diving. Water ranges 10-21°C, warmest January, February, March.
The Río Santiago wreck in Mar del Plata is a shallow, accessible dive, sitting at just 4m. We found it a fascinating spot for wreck enthusiasts who appreciate the history alongside the marine growth. The ship’s ribs and hull are well-colonised by local fish and crabs, making it an ideal site for macro photography and extended bottom times. It’s a compelling dive for those interested in a straightforward wreck exploration.
