About Silver Bank
Silver Bank, located about 70 miles north of the Dominican Republic, is a submerged carbonate plateau designated as the Sanctuary for the Marine Mammals of the Dominican Republic. This irregularly shaped bank, roughly 25 by 35 miles, features an average depth of 30 meters, with shallower areas reaching 18 meters or less, and a notable chain of coral heads along its northeastern edge. It serves as a vital winter haven for the entire North Atlantic Humpback Whale population, with thousands gathering here annually to mate, calve, and rear their young. From January to April, upwards of 5,000 humpback whales visit these warm, shallow waters, offering extraordinary opportunities for observing their natural behaviors. Visitors can witness mothers nurturing calves, aggressive displays between males competing for mates, and spectacular actions like breaching, spy hopping, lobtailing, and fin-slapping. The area is exclusively for soft encounters, meaning all in-water interactions are restricted to snorkeling, with scuba diving prohibited to protect the sanctuary's inhabitants. Access to Silver Bank is highly regulated, with only a few operators permitted to offer excursions, limiting visitors to less than 600 per season. This strict control ensures minimal disturbance to the whales and provides a unique, uncrowded experience. Visitors typically spend several days aboard a liveaboard, taking tender boats multiple times daily for close-up encounters with these intelligent and majestic marine mammals.

occasionalDive profile & how the dive runs
Access to Silver Bank is primarily through tenders launched from liveaboards. For whale encounters, you'll enter the water with a mask, snorkel, and fins, then passively drift at the surface. Scuba diving is prohibited near the whales to minimize disturbance. The maximum depth for typical reef exploration in shallower sections of the bank is around 25 meters, but the focus remains on surface interactions. Tender excursions typically last 1.5 to 3 hours, depending on whale activity. There is no specific 'turn point' or 'safety stop' as interactions are surface-based; however, tenders maintain close proximity to ensure diver safety and facilitate re-boarding.
Underwater photography
Silver Bank is a unique photography destination focused on natural light and wide-angle for humpback whales. You will primarily be snorkeling, so prioritize compact, high-quality wide-angle lenses (e.g., 8-15mm fisheye or 16-35mm rectilinear) to capture the whales' immense size and the vast blue backdrop. Natural light is essential; artificial strobes or video lights are generally discouraged or prohibited for whale interactions. Maintain a respectful distance and avoid aggressive pursuit, letting the whales approach on their own terms. Focus on capturing their natural behaviors, such as spy hopping or mother-calf interactions, with careful attention to composition and clean backgrounds. Buoyancy control is paramount even at the surface to avoid disturbing marine life or kicking up sediment.
Getting there & logistics
Access to Silver Bank is exclusively via multi-day liveaboard trips, typically lasting seven nights and six days, with five full days on the bank. These trips depart from Puerto Plata, Dominican Republic, with boarding generally on Saturday evenings and disembarkation the following Saturday morning. You will fly into Puerto Plata (POP) airport. The overnight crossing to Silver Bank takes 8-12 hours. Only a limited number of permitted operators are authorized by the Dominican government, so advance booking is essential, especially for peak season (February-March). Required fees include a Sanctuary & Port Fee (currently $500 USD per person) and potential fuel surcharges, which are not included in the trip fare. Ground transfers and hotels in Puerto Plata are not included, as the trip is liveaboard-based.
Safety & environment
Safety at Silver Bank is paramount, with strict protocols in place due to the nature of interacting with large marine mammals. All in-water whale encounters are snorkel-only; scuba diving is prohibited near the whales. Participants must remain passive at the surface and never pursue or touch the whales. Liveaboards are equipped with tenders for quick deployment and retrieval, ensuring close supervision during all in-water activities. The nearest recompression chamber is located in Santo Domingo, which is a significant distance from Silver Bank, making evacuation a complex and time-consuming process. Comprehensive dive and travel insurance, including emergency evacuation coverage, is highly recommended. Always adhere to the instructions of your experienced whale guides and liveaboard crew to ensure both your safety and the well-being of the whales.

FAQ
Silver Bank FAQ
When can you swim with humpback whales at Silver Bank?
The humpback whale season at Silver Bank runs from mid-January through mid-April, with peak activity in February and March. During this period, approximately 5,000 North Atlantic humpback whales migrate here annually to breed and calve in the warm, shallow waters. Trips are exclusively available during this specific window.
Do you need to scuba dive to see whales at Silver Bank?
No, whale encounters at Silver Bank are conducted as snorkeling experiences, not scuba dives. Scuba diving is strictly prohibited near the whales. Participants enter the water with mask, snorkel, and fins and float quietly at the surface, allowing the whales to approach on their own terms, in what are termed 'soft in-water interactions'.
How do you get to Silver Bank in the Dominican Republic?
Silver Bank is located about 130 kilometers north of the Dominican Republic coast. Access is exclusively via multi-day liveaboard trips departing from Puerto Plata. The crossing to the bank typically takes 8-12 hours overnight. Only a limited number of operators hold permits from the Dominican government to visit this protected marine sanctuary.
What marine life can I expect to see besides humpback whales?
While the primary draw is humpback whales, you may also encounter other marine life such as bottlenose and spotted dolphins frequently, as well as occasional hawksbill turtles. The reef formations in shallower areas can host various reef fish, nurse sharks, and manta rays, though these are secondary to the whale encounters.
Are there any strict rules for interacting with the whales?
Yes, there are very strict rules to protect the whales and ensure respectful interactions. You must remain passive at the surface, never pursue or chase the whales, and always maintain a safe distance. Touching the whales is strictly forbidden, and all activities are conducted under the close supervision of authorized guides to minimize disturbance.
Why dive Silver Bank from a liveaboard?
Silver Bank is one of Dominican Republic's signature dive sites. A liveaboard sleeps you on the water and puts you in the water for three to four guided dives per day, including dawn and night dives that day-boat operators rarely offer. You skip the daily commute back to port and reach quieter, less-crowded sites in the same region on a single trip.
