Why visit Rio San Juan
Rio San Juan is a low-key fishing village on the Maria Trinidad Sanchez coast, roughly 90 minutes east of Puerto Plata. It trades the all-inclusive bustle of the bigger resort zones for mangroves, hidden beaches and fresh seafood. The town is small enough to explore on foot, and almost everything worth doing is within a short ride of the central dock. Here are the highlights, starting with the one experience nobody should miss.
1. Take the Laguna Gri Gri boat tour
The signature thing to do in Rio San Juan is the Gri Gri lagoon boat tour. A local captain navigates freshwater channels lined with red mangroves, pauses at the Cueva de las Golondrinas sea cave, and finishes at Playa Caleton for a swim. It is calm, scenic and family friendly, and it is the reason most travelers come here in the first place.
2. Swim at Playa Caleton
This sheltered horseshoe cove just east of town has soft sand, shallow turquoise water and a row of local comedores serving fried fish. It is the gentlest beach in the area and a perfect spot for families. Read the full Playa Caleton guide for how to get there and the best time to go.
3. Relax or surf at Playa Grande
A few minutes east, Playa Grande is a long golden beach backed by cliffs and palms. It has more surf and a wilder feel than Caleton, with a beginner-friendly surf school and beach shacks. It is one of the most photogenic beaches on the entire North Coast.
4. Kayak or paddle the mangroves
For a quieter, self-paced version of the lagoon, rent a kayak or stand up paddleboard and glide through the channels on your own. The protected water is calm enough for beginners, and you get closer to the birdlife than a motorboat allows. Guided kayak and paddle trips include the gear and a local guide who knows the side channels.
5. Snorkel the North Coast reefs
Day trips from Rio San Juan and nearby Sosua reach calm reef spots full of tropical fish. A catamaran and snorkel cruise combines sailing, swimming and beach time, and is an easy add-on to a lagoon morning.
6. Eat fresh seafood in town
The village is full of small restaurants serving the catch of the day, from grilled snapper to garlic shrimp, often with rice, tostones and a cold Presidente. Eating where the locals eat is one of the cheapest pleasures of a visit.
7. Day trip to Cabrera and Laguna Dudu
About 25 minutes east, Cabrera is home to the Dudu cenote, a deep turquoise sinkhole with cliff jumping and a zipline. It pairs naturally with Rio San Juan on a longer day, as covered in our lagoon comparison.
8. Explore the wider North Coast
Rio San Juan is a good launch point for the broader coast. North Coast day trips reach Cabarete for kitesurfing and nightlife, Sosua for its sheltered bay, and Puerto Plata for the cable car up Mount Isabel de Torres.
How to plan your visit
Most people visit Rio San Juan as a day trip from a base in Cabarete, Sosua or Puerto Plata. If you are coming from the kitesurf coast, see our guide to Gri Gri from Cabarete and Sosua. With a single relaxed day you can do the lagoon tour and one beach. With two days you can add kayaking, snorkeling and the Dudu cenote.
