Rio San Juan

Río San Juan is a small coastal town in the María Trinidad Sánchez province of the Cibao Nordeste region, known for its stunning natural attractions — particularly the Gri Gri Lagoon, a network of mangrove-lined canals and limestone caves. With a population of around 8,000, it is a laid-back fishing village that has become a popular day-trip destination for visitors to the north coast.

The town sits at the mouth of the San Juan River, where it meets the Atlantic Ocean. The surrounding landscape is dramatic: towering limestone cliffs, dense mangrove forests, and hidden coves. Río San Juan gained wider recognition in recent years thanks to social media images of the Gri Gri Lagoon's emerald-green waters and the nearby Playa Caleton, a sheltered cove of white sand framed by coral reefs.

The climate is tropical, with temperatures averaging 25–31°C. The driest months are December through April. The rainy season (May–October) can make boat trips on the lagoon less predictable.
