My wife and I took this tour on our visit to the Domincan republic. We booked through Isaira tours. The tour van picked us up at 8:15 AM and we returned back to Puerto Plata at 6:00 PM (We also stopped at Playa Grande). Bathrooms at the lagoon are pay only, so bring 5 pesos. Lagoon was beautiful. Lots of pretty birds. Water was very clear and you could see fish swimming below the boat. The tour guide said that the lagoon suffered some destruction during hurricane Katrina. The ride through was pretty quick. After the lagoon we drove out to the swallow cave. We also stopped for a quick swim in one of the bays. Water is extremely clear in the area. Tour was pretty short and not too much interaction from guide. It was pretty, but I just felt we could have found something equally beautiful, a little closer.
