Rio San Juan is a pleasant fishing and farming town located approximately 100 km east of Puerto Plata. This town's fishermen provide the majority of this region's fish supply. You can see the boats leaving from the end of Calle Sanchez and purchase some of their daily catch from the pescaderos (fish vendors) along this same street. The area hosts a few charming accommodations, nice beaches and other attractive scenery - the most famous being the Gri Gri Lagoon. You can take boat tours through this lagoon's clear waters and see unusual rock formations entirely surrounded by magnificent mangrove trees to hidden caves and beaches. Snorkeling and diving can also be done in this area.
