Dive Site: Twin Sisters

About Twin Sisters

The Twin Sisters dive site features two 100-foot tanker wrecks, deliberately sunk and linked by heavy cables, creating a unique artificial reef habitat. These vessels lie parallel to each other, offering distinct diving experiences within a single site. The deeper of the two wrecks rests at approximately 24 meters (80 feet) and is notable for its spacious interior, where natural light penetrates and illuminates various compartments, making for impressive swim-throughs. The shallower wreck is situated around 15 meters (50 feet) and presents additional passages, suitable for certified wreck divers. Over time, both wrecks have been extensively colonized by marine life, forming vibrant artificial reefs covered in diverse marine growth. The site is part of the extensive diving offerings around Nassau, known for its healthy ecosystems and excellent visibility. Twin Sisters provides a captivating experience for divers interested in both wreck exploration and observing the rich biodiversity attracted to these structures, making it a popular choice for underwater photography.

Dive profile & how the dive runs

Dives at Twin Sisters begin with a boat entry, followed by a controlled descent to the shallower wreck at around 15 meters (50 feet). Divers then explore the passages and exterior of this vessel, observing the marine growth and resident fish. From here, the dive typically progresses to the deeper wreck, resting at approximately 24 meters (80 feet), where its spacious swim-throughs, illuminated by natural light, are a main attraction. The route involves navigating between the two linked tankers, allowing for ample time to investigate both structures. The turn point is determined by air consumption and bottom time, after which a gradual ascent is made along the shallower sections of the site. A safety stop at 5 meters is conducted before returning to the boat.

Underwater photography

Twin Sisters offers excellent opportunities for both wide-angle and macro photography due to its dual wreck structures and vibrant artificial reef life. A wide-angle lens is ideal for capturing the full scale of the 100-foot tankers, especially when photographing both wrecks or their extensive swim-throughs. Strobes are recommended to bring out the true colors of the marine growth and fish, even in the generally clear Bahamian waters. For macro enthusiasts, the wrecks provide numerous small subjects, including blennies, nudibranchs, and other invertebrates hiding within crevices and coral formations. Good buoyancy control is essential to avoid disturbing sediment inside the wrecks or damaging delicate coral growth. Be mindful of ambient light for internal shots within the deeper wreck’s compartments, as natural light streams through openings.

Getting there & logistics

Access to Twin Sisters is primarily via day boat trips departing from Nassau, New Providence, one of the main departure ports in the Bahamas. Lynden Pindling International Airport (Nassau) is the primary gateway for international arrivals. Most dive sites around Nassau are located just minutes from shore, ensuring short boat rides. Dive operators specializing in Nassau's local sites, such as Stuart Cove's Dive Bahamas, offer daily excursions. A typical dive trip to Twin Sisters is often combined with other nearby wrecks or reefs, forming a two-tank dive day. No specific permits beyond standard dive operator fees are generally required for this site. Divers should factor in local transportation from their accommodation to the dive shop's marina.

Safety & environment

Diving at Twin Sisters is considered suitable for certified divers with intermediate experience, particularly those comfortable with wreck penetration, given the available swim-throughs. The nearest recompression chamber is located in Nassau, New Providence, making emergency medical care accessible, though evacuation can still take time. Divers should always carry valid dive insurance that covers recompression treatment and emergency evacuation. Site-specific hazards include potential entrapment in confined spaces within the wrecks, especially for those venturing beyond designated swim-throughs, and possible sharp edges on the wrecks. Divers must adhere strictly to dive briefings, follow their guide's instructions, and maintain excellent buoyancy to prevent damage to the wrecks or injury from loose debris. Observing marine life should be done from a respectful distance, particularly around any sharks or stingrays.
