Puerto Plata and Sosúa

Many Sosua dives are easy enough for Open Water divers, but not every named site belongs in the same bucket. Shallow reef sites are forgiving; deeper walls require cleaner buoyancy, stronger situational awareness, and more deliberate gas planning. Expect site changes during north swell, winter squalls, and any tropical-weather period. Use an SMB on advanced or busy-traffic dives, stay close to your guide in shallow mixed-use areas, and avoid forcing a second dive if seasickness, fatigue, or poor equalization show up early. Cruise passengers should choose conservative profiles and operators with disciplined return logistics.

Emergency care is strongest in Puerto Plata and along the Sosua-Cabarete corridor. Call 911 for urgent assistance and keep POLITUR / CESTUR in your phone for tourist-zone support. Centro Medico Bournigal is the major private hospital on the North Coast, and Centro Medico Cabarete is useful for the Sosua side of the corridor. Hyperbaric medicine is available in Puerto Plata through Diagnostico Medico Mayans / OXIFLOW RD, but chamber readiness can change, so confirm current decompression support with your operator, insurer, and emergency contacts before the first dive day.

Sosua Marine Park was created to manage the bay through zoning, rules, and sustainable use. That means visitors should dive and snorkel with low-impact habits: no touching coral, no kneeling on the reef, no collecting shells or historical objects, no wildlife feeding, and no careless finning over restoration areas. Mooring buoys exist to reduce anchor damage, and conservation groups such as Fundacion Ecologica Magua are actively involved in reef stewardship and restoration. The best operators talk about these rules before splash time. If yours does not, ask.
