Why dive here
With 503+ marine species recorded in the area - including barracuda, blue sharks, dolphins, eagle rays and humpback whales - A.REGINA offers some of Rincon & West Coast's richest wreck diving. Water sits around 27°C.
A. Regina isn’t your typical deep wreck dive, and that’s precisely why we love it. Sunk in 1985, this massive roll-on, roll-off ferry met its end not far from Mona Island, but her bow section, surprisingly intact, now rests in just two metres of water near Rincon. The sheer size, even of just the bow, is impressive as you approach, a hulking shadow just beneath the surface. This is a snorkeler’s dream, or a shallow diver’s playground. We’ve spent hours here, just floating above the bridge structure, watching schools of juvenile snapper dart in and out of the wheelhouse windows. The ambient light is incredible, painting the coral growth in vivid colours. You can fin right over the deck, peeking into the cargo holds where light shafts pierce the gloom, revealing the ghostly outlines of machinery and pipes now covered in sponges. Barracuda often cruise lazily overhead, silhouetted against the bright surface. It’s a completely different wreck experience – no decompression limits, just pure exploration and fantastic light. Our favourite time to visit is mid-morning, when the sun is high, illuminating every detail without creating harsh shadows. It’s a unique piece of history, surprisingly accessible, and a real treat if you’re looking for something beyond just another reef.

The A. Regina was a roll-on/roll-off passenger and vehicle ferry built in Norway in 1967. For nearly two decades, she plied the waters of the Caribbean, connecting islands and transporting people and goods. Her career came to an abrupt and dramatic end on February 15, 1985. While on a voyage from Mayagüez, Puerto Rico, to the Dominican Republic, the vessel ran hard aground on a reef just south of the remote and beautiful Mona Island. The grounding was severe, and despite efforts to refloat her, the A. Regina was declared a total loss and abandoned to the sea.
Today, the wreck of the A. Regina is a spectacular and sprawling dive and snorkel site. Resting in water as shallow as 2 meters, the vessel has been torn apart by decades of storms and relentless wave action. The bow section is recognizable, but much of the hull has collapsed, creating a massive field of steel plates, corridors, and vehicle decks for divers to explore. This metallic skeleton has been thoroughly colonized by the vibrant reef, with corals, sponges, and schools of tropical fish turning the tragedy into a thriving marine habitat. Its shallow depth and the sheer scale of the wreckage make the A. Regina a must-see site for anyone diving the wild west coast of Puerto Rico.
