- From Punta Rucia: RD$1,500-2,500 per person, 30-minute boat ride, usually includes snorkel gear and drinks
- From Buen Hombre: Sometimes cheaper, similar boat ride duration
Organized tours from Puerto Plata include transportation and run USD $70-120 per person. The trip is weather-dependent -- rough seas can cancel departures.
- Snorkeling gear: Tours provide basic gear, but your own mask fits better
- Underwater camera: The reef life is spectacular
- Reef-safe sunscreen: Absolutely mandatory in this protected area
- Cash: For the boat tour and tips
- Seasickness medication: If sensitive -- the open ocean crossing can be bouncy

- This is one of the best snorkeling experiences in the entire Caribbean -- do not miss it if you are in the northwest
- Book the earliest boat departure for the clearest water and fewest other visitors
- Bring reef boots or water shoes for the coral sand
- The boat ride itself passes through beautiful mangrove channels and open ocean
- Tip your boat captain well (RD$200-500) -- they are local fishermen sharing their ocean
