Each winter, between 3,000 and 5,000 North Atlantic humpback whales funnel into a shallow, coral-studded plateau 80 miles north of the Dominican Republic — one of only three places on Earth where you can legally swim alongside them.
The Silver Bank is one of only three places on Earth where you can legally swim alongside humpback whales.
If you want the most intimate, ethically regulated whale encounter in the Caribbean, Silver Bank is it — but it demands serious advance planning and a budget north of $3,500 per person. Samana Bay offers a more accessible, family-friendly alternative for half-day boat tours at $50–$85 per person, but you won’t get in the water there. Choose Silver Bank if your family craves a multi-day expedition with marine biologists; choose Samana if you’re traveling with younger kids or working with tighter time and money.
Adventure travelers
Marine life enthusiasts
Conservation-minded visitors
The Dominican Republic’s Silver Bank (Santuario de Mamíferos Marinos) isn’t a typical whale-watching stop. It’s a protected marine sanctuary that was designated in 1986 — the country’s first — and later expanded in 1996 to cover over 30,000 square kilometers. Only three licensed operators are allowed to run trips here, and fewer than 600 visitors per season get permits to enter the water. That exclusivity is deliberate: it keeps the whales undisturbed and the experience genuinely wild.
This guide covers exactly what a Silver Bank expedition looks like, from the migration patterns of the humpbacks to the daily rhythm aboard a liveaboard vessel, plus how to book a spot when fewer than 200 people per week are allowed in. Whether you’re planning a bucket-list trip or just curious what makes this sanctuary different from every other whale-watching destination in the Caribbean, you’ll find the research-backed details here.

The Silver Bank Sanctuary: A Protected Haven for Whales
Situated about 100 kilometers north of the Dominican Republic and 150 kilometers east of the Turks and Caicos, the Silver Bank is an irregularly shaped submerged carbonate plateau. The warm Caribbean waters here average 60 to 90 feet deep across a roughly 20-by-40-mile area — shallow enough to create a calm nursery for newborn calves. The sanctuary was originally established on October 14, 1986, under law 67-74, making it the Dominican Republic’s first marine mammal sanctuary. A presidential decree on July 5, 1996, renamed and expanded it to cover Samana Bay, the northern and eastern coastline, and deep-ocean migration routes.
The sanctuary now covers over 30,000 square kilometers, making it the largest protected area in the Dominican Republic. Critically, only about 10 percent of the platform is open to tourism; the rest remains completely undisturbed. The Dominican Republic partners with organizations including The Nature Conservancy, the University of Miami, the Center for Coastal Studies, and the Smithsonian Institution to manage the site. Permit fees fund enforcement patrols and research conducted by CEBSE and the Ministry of Environment.
Visitors are limited to fewer than 60 people per week across all three operators — roughly 150–200 guests per week total. You’ll need to book 12 to 18 months ahead to secure a spot.
The Humpback Whales of Silver Bank
Northwestern North Atlantic humpback whales leave their summer feeding grounds off New England, Canada, and Greenland between December and April to reach the warm Caribbean. The Silver Bank offers water temperatures of 26–28°C, few predators, and sufficient depth for courtship behaviors without exposure to open-sea swell. Pregnant females give birth and nurse their calves here; estrous females seek mates while males experience testosterone peaks and engage in high-competition behaviors.
A 2005 NOAA population count aboard the R/V Gordon Gunther recorded between 5,000 and 7,000 humpbacks within the sanctuary’s oddly shaped, 40-square-mile core area. The Silver Bank contains the largest seasonal population of humpbacks in the North Atlantic Ocean, if not the world. Field operators regularly report concentrations of 20 to 40 groups visible from the mother ship’s deck on the same day.
Surface behaviors you’ll witness include breaching, lob tailing, fin slapping, and spy-hopping. Males become more vocal during this period, producing haunting songs with moans, chirps, and ascending wails that vibrate through the water and can be felt physically. You’ll also see heat runs — groups of up to a dozen males chasing a single female — and rowdy groups where two or more males compete for proximity. Other marine mammals documented in the area include sperm whales, pilot whales, minke whales, Bryde’s whales, Cuvier’s beaked whales, orcas, and several dolphin species.
Mid-February typically offers the highest probability of spectacular displays including breaching and courtship behavior. Book your liveaboard for the third week of February if you can — that’s when the peak concentration of mothers, calves, and singing males overlaps with the calmest weather windows.
The Liveaboard Experience: Six Days on the Water
Liveaboard trips run from late January through mid-April, with February and March as the peak season. Trips depart from Puerto Plata on the north coast of the Dominican Republic and include six full days of in-water encounters. Guests stay aboard vessels operated by one of three permitted companies: Aggressor Fleet aboard the Turks & Caicos Aggressor II, Aquatic Adventures aboard the Turks & Caicos Explorer II, or Conscious Breath Adventures aboard the Sea Hunter.
These are all-inclusive packages covering accommodation, three meals daily, guides, park fees, and tender transport to and from the whale encounters. Cabins are shared or private, and Wi-Fi is limited or nonexistent — intentional, to keep you present with the whales. Evening naturalist presentations cover humpback whale ecology, migration patterns, and conservation, often led by marine biologists with years of field experience. Underwater photographers occasionally present as well.
Daily activities follow a rhythm of two zodiac or panga expeditions per outing, with free time between for reading, photography editing, or simply watching the surface from the deck. The in-water experiences are strictly snorkel-only — no scuba diving is permitted in the protected area. Water temperatures average around 78°F (26°C), and a 3mm wetsuit is recommended. Visibility in the sanctuary ranges from 10 to 20 meters.
Each day starts with a naturalist briefing on whale behavior, safety protocols, and the soft in-water encounter rules. Guides review approach techniques and the day’s plan based on whale locations. Check your wetsuit, mask, and snorkel — the official sanctuary guidelines require no flash photography and no touching.
Small tenders carry 6–8 guests to the encounter zone. Trained guides position the boat for passive observation — engines off or in neutral — allowing whales to approach on their terms. Operators follow a maximum encounter time per whale group to prevent stress.
Snorkelers enter the water quietly and float at the surface. Whales may swim within meters, including mother-calf pairs, singing males suspended head-down, or groups engaged in courtship. Snorkeling conditions at Silver Bank typically offer visibility of 10–20 meters. Guides signal immediate withdrawal if animals show stress.
Between in-water sessions, guests observe surface activity from the zodiac — breaches, pec slaps, tail lobs, and spy-hopping. Bring a wide-angle lens for underwater shots; a 70-200mm telephoto works well for surface breaches. Tips for swimming with whales at Silver Bank recommend avoiding strobes to reduce backscatter from marine snow.
Back aboard the mother ship, guests dry off and debrief. Evenings feature naturalist-led presentations on humpback whale lifecycles, migration science, and conservation efforts. Photo-ID submissions to Happywhale help researchers track individual whales across seasons.
Seasickness can hit even seasoned travelers — zodiac transfers and open-water conditions are unpredictable. Pack seasickness tablets or patches and start taking them 30 minutes before boarding. Stay hydrated with at least two liters of water per day; alcohol and coffee dehydrate rather than help.
Planning Your Silver Bank Expedition
The cost for an all-inclusive liveaboard package ranges from $3,500 to $5,500 USD per person for the week. This covers accommodation, meals, guides, park fees, and tender transport. Flights to Puerto Plata (POP), gratuities (15–20 percent), wetsuit rentals, and alcohol are typically extra. Budget an additional $40–$120 per night for a hotel in Samana town or $80–$250 per night in Las Terrenas if you arrive a day early — which is strongly recommended.
Puerto Plata receives direct flights from Frankfurt, Zürich, Montreal, Toronto, Winnipeg, New York, and Miami. Domestic flights connect Puerto Plata and Santo Domingo. You can also fly into El Catey International Airport (AZS), located 40 minutes west of Santa Barbara de Samana, or Santo Domingo (SDQ), a 2.5-hour drive from the north coast. Plan to arrive at least 24 hours before departure to account for flight delays and lost luggage.
Many travelers combine the liveaboard with time on the North Coast, exploring Victorian architecture in Puerto Plata, Mount Isabel de Torres, Cabarete, and Sosúa before or after the expedition. Samana Bay, about 80 nautical miles south, offers a completely different experience — half-day catamaran tours for $50–$85 per person with 95 percent sighting success rates during peak season, though swimming with whales is not permitted there.
Book your liveaboard 12–18 months in advance. Permits are strictly limited to roughly 150–200 guests per week across all three operators, and February and March slots sell out first. For Samana Bay half-day tours, booking one week ahead during peak season is usually sufficient, though weekend departures go faster.
Booking & Budgeting for Silver Bank
The real friction point for most travelers is the combination of high cost, limited availability, and the need to coordinate international flights with a fixed liveaboard departure. Here’s what the research supports for making it work.
| Expense | Cost Range | Notes |
|---|---|---|
| Liveaboard (6 days, all-inclusive) | $3,500–$5,500/person | Covers accommodation, meals, guides, park fees, tenders |
| Flights to Puerto Plata (POP) | Varies by origin | Direct from NYC, Miami, Toronto, Frankfurt, Zurich |
| Hotel (Samana town, peak season) | $40–$120/night | Budget to mid-range options near the waterfront |
| Hotel (Las Terrenas, peak season) | $80–$250/night | More upscale, good for post-expedition relaxation |
| Gratuities | 15–20% of package | Customary for liveaboard crew and guides |
| Wetsuit rental | Extra | 3mm recommended; pack your own to save |
| Meals in Samana (local comedores) | $5–$8/meal | Affordable eats near the waterfront |
Children under 3 are generally not permitted on whale watching boats in the Dominican Republic. For Silver Bank liveaboards, most operators recommend a minimum age of 10–12 due to the duration, remote location, and physical demands of snorkeling in open water. Samana Bay catamaran tours are suitable for ages 4 and up, but check with your operator about specific age policies before booking.
- Silver Bank is one of only three places on Earth where you can legally swim with humpback whales — permits are capped at roughly 150–200 guests per week, so book 12–18 months ahead.
- The season runs late January to mid-April; February and March offer the highest concentration of mothers, calves, and singing males, with mid-February typically delivering the most dramatic surface displays.
- Budget $3,500–$5,500 per person for the liveaboard plus flights to Puerto Plata, hotels, gratuities, and gear. Samana Bay half-day tours ($50–$85) offer a more accessible alternative without in-water access.
Before You Go — Silver Bank
Can you swim with whales in the Dominican Republic?
Yes, but only at Silver Bank under strictly regulated conditions. Swimming with whales is not permitted in Samana Bay or anywhere else in Dominican waters. Silver Bank is one of only three locations worldwide where in-water encounters with humpback whales are legally allowed.
How much does a Silver Bank liveaboard cost?
All-inclusive packages range from $3,500 to $5,500 per person for a six-day trip. That covers accommodation, meals, guides, park fees, and tender transport. Flights to Puerto Plata, gratuities (15–20 percent), wetsuit rentals, and alcohol are extra.
What’s the best month to visit Silver Bank?
Mid-February through early March offers the highest concentration of humpback whales and the most reliable weather. The official season runs January 15 to March 31, with peak sightings from late January through early March. Book February dates if you want the best chance of seeing breaching and courtship displays.
Is Silver Bank suitable for children?
Silver Bank liveaboards are generally not recommended for children under 10–12 due to the week-long duration, remote location, and open-water snorkeling conditions. Samana Bay half-day tours are suitable for ages 4 and up on stable catamaran-style boats, with naturalist commentary geared toward younger audiences. Children under 3 are not permitted on whale watching boats in the Dominican Republic.
What should I pack for a Silver Bank expedition?
Reef-safe sunscreen with high SPF, a wide-brimmed hat, polarized sunglasses, a waterproof bag for electronics, seasickness medication, layered clothing for cool mornings and evenings, a camera with a wide-angle or telephoto lens, binoculars, and a reusable water bottle. A 3mm wetsuit is recommended — pack your own to avoid rental fees. Avoid wearing strong perfumes or fragrances.
Why This Sanctuary Matters
The Silver Bank sanctuary represents a rare balance between human wonder and wildlife protection. When the Dominican Republic designated it a protected area in 1986, it wasn’t just creating a tourist attraction — it was establishing a model that the International Whaling Commission now recognizes as a critical protection zone for humpback whales. The permit system, the three-operator limit, the passive encounter protocol, and the research partnerships with organizations like the Center for Coastal Studies and the Smithsonian Institution all point to the same idea: that some experiences are worth preserving precisely because they remain difficult to access.
