Exploring the Berwyn: A Guide to Carlisle Bay Shipwrecks

The Vibe

The transition from the shallow sandbars of Carlisle Bay into its dense biological environment feels like stepping into a curated gallery crawl. History and marine biology collide just a 200-metre swim from the shoreline. The atmosphere beneath the surface is heavily populated and fiercely competitive, supporting massive schools of yellowtail snapper darting through the rusted iron ribs and encrusted concrete of intentionally sunken vessels. These structures span over a century of maritime history. It is a precise ecosystem where you can float effortlessly above the shallow ruins of a mutinous WWI tugboat, then dive down to trace the ghostly hull of a 1990s drug-running freighter.

Just offshore from the UNESCO World Heritage site of Bridgetown, the Carlisle Bay Marine Park offers a stark contrast to standard Caribbean reef topography. The underwater environment leans slightly adventurous but remains highly accessible for those equipped with the right information from our Equipment & Safety Guide. Rather than traditional coral flats, snorkelers navigate a complex “spaghetti junction” of swim-throughs built upon historic wreckage. It functions as a living underwater museum that bridges the island’s colonial past with its highly regulated, modern marine conservation efforts. For a broader overview of how this fits into the island’s coastal geography, refer to our Ultimate Guide to Snorkeling in Barbados.


Category 1: The Berwyn Tugboat

The Berwyn is a 70-foot (21-metre) World War I French tugboat that serves as the cornerstone of Carlisle Bay’s artificial reef system. Deliberately scuttled by its own crew in 1919, historical records and local maritime logs indicate the French sailors sank their own vessel simply because they had grown exceedingly fond of Barbadian rum and the island’s lifestyle. They outright refused the captain’s orders to return to a devastated post-war Europe.

Today, the Berwyn is highly accessible for shore-based exploration. Pinpoint the general wreck site using approximate GPS coordinates 13.0882, -59.6143. While the vessel rests on the sandy seabed at a depth of 20 feet (6 metres), its upper superstructure sits a mere 7 to 10 feet (2 to 3 metres) below the surface, heavily dependent on the tidal shift. As the oldest sunken ship in the marine park, it has enjoyed over a century of undisturbed marine colonisation. Its decaying iron hull has completely transformed into a dense biological substrate, heavily encrusted with soft sponges, hard corals, and massive brain coral formations. Navigating its shallowest points requires careful buoyancy control. Do not touch the ancient coral heads. The consistently warm seasonal water temperatures, ranging from 26°C to 29°C (78°F to 84°F) year-round, promote rapid yet highly fragile reef growth.


Category 2: The Ce-Trek Concrete Reef

Moving deeper into the marine park, the Ce-Trek offers a completely different structural profile. Sunk in January 1986, this 45-foot derelict vessel stands out from the rest of the sunken fleet because it is constructed entirely from ferro-cement (concrete) rather than traditional iron or wood. Resting at a moderate depth of 40 to 45 feet (12 to 13 metres), the Ce-Trek demands a more capable free-diving approach for close inspection.

The rough concrete surface of the Ce-Trek acts as an exceptional anchor point for marine flora. It serves as a primary feeding ground for large parrotfish, whose distinct scraping sounds can be heard clearly underwater as they consume algae off the cement hull. The intricate nooks of the vessel also act as prime macro-photography habitats. Patient divers frequently spot elusive marine life such as frogfish and long-snout seahorses hiding within the artificial crevices. If you are planning an excursion focused on photography, our guide on Best Time & Weather for Snorkeling details the optimal months for maximum water clarity.


Category 3: The Eilon Drug Runner

The largest and arguably most notorious vessel on this circuit is the Eilon, a 110-foot (33-metre) Colombian freighter with a heavily documented dark past. The ship was seized by the Barbados Coast Guard in the early 1990s after interceptors found it stuffed entirely with marijuana lining its interior walls. After being tied up at the Bridgetown Careenage for six years, the Eilon was intentionally scuttled on June 8, 1996.

It now rests at a jaunty angle on the seabed at a maximum depth of 55 feet (17 metres). Due to its size, the superstructure reaches much closer to the surface, making it easily visible from above. The Eilon features a famous air pocket in its bow at a depth of 25 feet (7.5 metres). While the trapped air is highly toxic and entirely unsafe to breathe, the pocket is physically large enough for experienced free-divers to briefly surface internally for a rapid, surreal photograph. For those interested in exploring the Eilon after sunset, consult our comprehensive briefing on Night Snorkeling in Barbados to understand the nocturnal shifts in the local current.


Category 4: The Bajan Queen & Beyond Carlisle Bay

A comprehensive Carlisle Bay shipwreck map must include the Bajan Queen. Originally operating as the Pelican, a tugboat servicing Bridgetown Harbour, she was converted into a party boat before being deliberately sunk in 2002. She rests at a depth of 35 feet (10 metres), with her upper decks reaching within 10 feet (3 metres) of the surface. The vessel is heavily colonised by barrel sponges and frequently surrounded by schools of Atlantic spadefish. The remaining vessels in the bay’s six-ship fleet include the Cornwallis, a Canadian freighter sunk by a WWII torpedo, and a naval landing craft known simply as the Barge.

While Carlisle Bay dominates the shallow snorkelling scene, advanced free-divers exploring Barbados shipwrecks often head eight miles north to Folkestone Marine Park. Here lies the SS Stavronikita, a massive 365-foot Greek freighter deliberately scuttled in 1978. Resting at a formidable depth of 120 feet (36 metres), its masts reach up to 20 feet (6 metres) from the surface, making the upper rigging accessible to highly capable snorkellers. Do not attempt the Stavronikita without a surface marker buoy and a dive buddy.


Carlisle Bay Shipwreck Map & Route Guide

Visualising the layout of the six vessels is crucial before entering the water. While physical waterproof guides are sold at local dive shops, you can easily navigate the site using this mental Carlisle Bay shipwreck map. Think of it as your definitive Barbados snorkelling map for the marine park. The wrecks are clustered within a 200-metre radius, roughly 200 metres off the beach from the Harbour Lights club. The site is highly concentrated. You do not need to swim long distances between the hulls.

For the most efficient route, begin your swim from the shoreline directly opposite the lifeguard tower at Browne’s Beach. Head straight out to the Barge and the Cornwallis fragment. These sit in extremely shallow water and serve as an excellent warm-up for equalising your ears. From there, swim 30 metres west to the Berwyn. Once you finish inspecting the tugboat’s coral-encrusted hull, follow the scattered 19th-century anchors on the seabed. This marked trail leads directly to the deeper trio: the Bajan Queen, the Ce-Trek, and finally the Eilon.


Traveller Advice & Pro Tips

Logistical preparation dictates the quality of your experience in Carlisle Bay. Because the six shipwrecks—including the Berwyn, Ce-Trek, and Eilon—are grouped so closely together, the layout mimics a designated underwater trail. This specific route is physically marked on the sandy seabed by scattered 19th-century anchors, concrete blocks, and sunken cannons. Following these markers ensures you do not miss the smaller transitional habitats between the primary wreck sites.

Do not rely on surface navigation alone; use the sunken cannons and 19th-century anchors scattered on the seabed to guide you from the shallow hull of the Berwyn to the deeper deck of the Eilon.

Accessing the site from the shore is highly straightforward, though many visitors opt for the infrastructure provided by the local beach clubs that operate directly on the sand adjacent to the marine park. You can secure a day pass which typically covers your facilities, a security locker, and transport to the buoys.

Facility / OperatorPrice (USD)Inclusions & Details
Harbour Lights Beach Club$50.00Includes a “Turtle & Shipwreck Snorkel Tour Combo” launching directly from the beach, plus lounger access.
The Boatyard$35.00Targeted at cruise passengers. Includes a 45-minute guided shipwreck snorkel tour, transport back to port, and beach chair.
Copacabana BarbadosVariesOffers independent locker rentals and heavy-duty buoy floats for self-guided shore snorkelers.

If you prefer a dedicated maritime approach rather than swimming out from a beach club, booking a dedicated vessel ensures you conserve energy for the actual diving. For instance, you can join a 90-minute turtle and shipwreck adventure which departs directly from the Bridgetown careenage and drops you directly atop the Eilon. Alternatively, those looking to combine their wreck exploration with broader coastal sightseeing frequently book a catamaran snorkelling cruise, which provides the added benefit of high-visibility entry platforms and onboard safety briefings. Explore our directory of Guided Tours & Lessons for a complete breakdown of operator safety records and vessel specifications.

Finally, while navigating the wrecks, you will inevitably encounter the resident hawksbill turtle population that frequents the bay. It is critical to adhere to the strict local guidelines regarding wildlife interaction. We strongly advise reading our briefing on Turtle Etiquette: Swimming Responsibly with Hawksbills to understand why feeding the wildlife is detrimental to the ecosystem. After your dive, the immediate proximity to the capital makes it easy to transition into Other Things to Do in Barbados, such as exploring the historic Garrison or visiting the nearby Mount Gay rum distilleries.

Always carry a highly visible marker buoy when attempting the 200-metre swim from shore. The waters above the Ce-Trek and Eilon see heavy recreational boat traffic, and a surface marker is non-negotiable for your safety.
