The Gri-Gri lagoon is located near Rio San Juan, on the magnificent Costa Verde, which links the province of Puerto Plata to the Samana peninsula. Take a boat from the small makeshift port and sail for 1 km through the mangroves, past the magnificent mangrove trees that grow in the water and far above the water level, and then along the coast to some of the region's most picturesque beaches, such as Playa Caleton.
Halfway between the Amber Coast (Cofresi, Puerto Plata, Sosua and Cabarete) and the Samana peninsula, the Rio San Juan region is off-centre and difficult to access, between the Puerto Plata and Samana airports. It is therefore unspoilt, and there are few hotels. We are on the north coast of the Dominican Republic, 80 km east of Puerto Plata airport and 130 km west of Samana airport. Here, it's not the Caribbean Sea, but the Atlantic Ocean, with its waves ideal for surfers and kite surfers. The two nearby centres of interest are the superb Playa Grande beach and the Gri-Gri lagoon.

Editor's tip
Avoid Saturdays and Sundays - they're too crowded!
Playa Grande
On the Costa Verde, near Rio San Juan, one of the country's most beautiful beaches and the longest on the north coast lives up to its name. Fringed by coconut palms, it offers a wide stretch of golden sand stretching for several kilometres, where you can get away from it all. A favourite weekend destination for Dominicans, it remains accessible to visitors who come from far and wide to enjoy its translucent waters. Restaurants, bars and musicians liven up the central area.
Not too many tourists here, just locals enjoying a good local beer. "Beware of falling coconuts, drink at your own risk" says the sign above the bar...
🍴 Tiburón Drinks
Tiburón Drinks is a very pleasant beach bar with a perfect location at the end of Playa Grande. It's the perfect spot to enjoy a drink while taking in the views of the beach. Wait until the sun goes down to take in the sights.
