Snorkeling at Dog Island's Famous Shipwreck

The True History of the Buenaventura Shipwreck

The iconic shipwreck resting off the white sand beach of Isla Perro Chico (Dog Island) is the Buenaventura, a Colombian cargo vessel that met its fate in 1958. Departing from the port of Colón loaded with mixed general merchandise, food staples, and beverages, the vessel suffered a navigational calculation error amidst low nocturnal visibility, violently striking the barrier reef surrounding the cayo and disabling its engine.

When another cargo vessel named Honduras rushed in to tow and salvage the stranded ship, a sudden fire broke out on board. The native Guna community immediately sprang into action, navigating their traditional wooden cayucos through the surf to rescue the entire stranded crew without a single casualty.

Elderly Guna community leaders who witnessed the disaster recall how, lacking modern scuba gear, islanders used traditional ingenuity—diving into the flooded cargo holds with stout ropes secured around their ankles to haul up surviving provisions before the vessel settled permanently into the seabed. Today, the Buenaventura stands as a living historical monument and the premier snorkeling destination in San Blas.

Depth Profile & Marine Biodiversity

The sunken shipwreck at Dog Island (Isla Perro Chico) is featured in all our guided San Blas boat tours and day trips from Pelicano Island. All overnight and day trip guests receive complimentary snorkeling gear and masks to explore this magnificent artificial reef:

The shipwreck lies just 20 to 30 meters from the shoreline in crystal-clear water. Its highest steel ribbing actually breaks the surface at low tide (0 meters depth), while its deepest keel section rests gently on the white sand seabed at only 2 to 4 meters (6 to 13 feet), making it fully explorable with just a snorkel mask without free-diving experience.

• Dense Reef Fish: Sergeant majors, yellowtail damselfish, queen angelfish, and vibrant stoplight parrotfish swarm around the coral-encrusted bulkheads, utilizing the rusted hull as permanent shelter.
• Coral Formations: Decades of gentle wave action have covered the metal plating in healthy brain corals, orange cup corals, and swaying sea fans.
• Spotted Eagle Rays & Nurse Sharks: Along the sandy seabed perimeter where the reef meets open water, gentle southern stingrays and spotted eagle rays frequently glide past, while hawksbill sea turtles feed peacefully on sponges.

Safety & Snorkeling Tips

• Avoid Touching Rusted Metal: Sharp edges and stinging fire corals grow directly on the steel; maintain a safe 1-meter swimming clearance.
• Gentle Currents on Outer Side: While water within the cove is calm, a gentle current flows past the outer hull into the channel. Swim with a buddy or wear fins.
• Shore Entry: No deep-water jumping required; you can wade directly from the powder-white sand beach and swim just 20 meters to reach the bow.
