Silver Bank

The trip is a week, not a day. Boats leave Ocean World Marina in Cofresí, just west of Puerto Plata, on a Saturday evening and cross overnight, reaching the bank around nine the next morning after roughly ten hours at sea. The mothership then moors inside the reef for five full days, and every day but the travel days brings two tender outings, morning and afternoon, built around the same routine: run out, watch for blows and surface activity, ease alongside a resting or socializing group, and slip snorkelers into the water a few at a time to hold position and let the whale close the distance or not.

Only three permits are issued for the entire Sanctuary for the Marine Mammals of the Dominican Republic, capping the whole season at roughly 540 guests, and no vessel may cross onto the bank without one. Scuba is banned outright — the guidelines are built around a passive, whale-initiated approach: float still, breathe through a snorkel, and let a resting mother and calf, or a competing group of males, come to you. A strong encounter can mean an hour close to motionless in the water with an animal the length of a bus a few metres off; a slow one can mean nothing surfaces close enough to enter for at all.

Conditions are open Atlantic, not a sheltered reef trip. Water sits in the low-to-mid 20s Celsius, sanctuary rules halt tender operations outright once wind passes 25 mph, and both the overnight crossing and the week at anchor move with ocean swell, so seasickness remedies are worth packing alongside mask, fins, snorkel and a wetsuit. The minimum age is eight, with a parent required in the water for younger children. Whale activity is never guaranteed on any single outing — operators plan for six to eight hours of searching most days and treat a close, calm approach as the payoff for the outings that come up empty.
