Hidden on the north coast of the Dominican Republic, in the charming seaside town of Río San Juan, lies one of the island’s most magical natural treasures — the Blue Lagoon, locally known as Laguna Gri Gri. This serene lagoon is surrounded by mangrove forests, crystal-blue waters, and tropical wildlife, is one of the best places to visit in the Dominican Republic. Recognized as a Protected Natural Monument, Laguna Gri Gri is a must-visit for anyone seeking a mix of relaxation, nature, and eco-adventure. Whether you’re gliding through calm canals, photographing reflections, or birdwatching in silence, every corner of this lagoon tells a story of harmony between land and sea.
Laguna Gri Gri is unlike any other attraction in the Dominican Republic. A boat journey through its narrow mangrove channels reveals shimmering blue waters, twisting tree roots, and flashes of tropical birds darting through the sunlight.
As your boat emerges into the open sea, you’ll discover hidden gems like the Cueva de las Golondrinas (Cave of the Swallows) and a secluded turquoise cove perfect for swimming or snorkeling. The calm, mineral-rich water reflects sunlight beautifully, creating a glowing blue hue that gives this lagoon its nickname — the Blue Lagoon.
A Sanctuary of Wildlife and Natural Wonders
Laguna Gri Gri is also a haven for birdwatchers and eco-travelers. Its mangrove ecosystem shelters herons, pelicans, cormorants, and dozens of native species. Beneath the water, fish and small marine creatures weave through the mangrove roots, showcasing the lagoon’s rich biodiversity. It’s one of the best examples of eco-tourism in the Dominican Republic, offering travelers an opportunity to enjoy nature while supporting local conservation.

Just a short 45-minute drive from Laguna Gri Gri, you’ll find another incredible natural attraction — Laguna Dudú, a natural blue-water cenote that’s a dream come true for adventurous travelers.
💦 A Cenote Full of Thrills
Laguna Dudú is made up of two freshwater sinkholes connected by an underwater cave system. The water glows an intense blue, inviting visitors to swim, dive, or zipline across its surface. For those seeking an adrenaline rush, the zipline lets you glide above the lagoon and plunge into the refreshing waters below — a favorite experience for thrill-seekers.
🌴 Relaxation and Nature in Perfect Balance
