Why visit Laguna Gri Gri
Laguna Gri Gri is a small mangrove lagoon in the village of Rio San Juan, on the Maria Trinidad Sanchez coast. The boat tour follows freshwater channels lined with mangroves out toward the cliffs, stops at the Cueva de las Golondrinas sea cave, and ends at Playa Caleton beach. It is much quieter than Laguna Dudu or the bigger Cabarete attractions, and remains one of the most peaceful Caribbean lagoon experiences in the country.
