Laguna Gri Gri is the calm green heart of Rio San Juan, a mangrove lagoon you explore by small boat. Below are 3 lagoon tours that glide through the natural canals, past the swallow cave and out to hidden Caribbean beaches.
Why take a Laguna Gri Gri boat tour
The classic outing leaves from the village dock in Rio San Juan and follows narrow channels lined with red mangroves. Guides point out herons, egrets and the occasional kingfisher, then steer into the Cueva de las Golondrinas, a limestone sea cave alive with nesting swallows. Most trips finish with a swim stop at Playa Caleton, a sheltered cove with calm, clear water.
What to expect on the water
Boats are small and the pace is slow, so this is a gentle, family friendly trip rather than a thrill ride. Mornings are calmest and best for birds. Bring a hat, sunscreen and a dry bag for your phone. A typical loop runs around two hours, and life jackets are provided on board.
