Best Time to Visit Gri Gri Lagoon
Dry season versus rainy season
December to April is the driest stretch on the north coast, with warm days and the calmest conditions for the lagoon and the boat trip to Playa Caleton and the swallow caves. May to November brings more rain, usually brief afternoon showers, and the open-sea section of the tour can be choppier on windy days. The mangroves are scenic year round.
Best hours and avoiding crowds
Morning tours generally have the calmest water and the best chance of spotting birds among the mangroves. Weekends and Dominican holidays bring local visitors to Rio San Juan and Playa Caleton, so a weekday trip is quieter. Booking ahead means you join the first boats of the day rather than waiting at the dock.
