Five-hour tours of the wetlands are arranged by Aamvecona, a conservation organization of mostly volunteers working in close conjunction with the Ministry of the Environment. Tours leave from the road bridge over the Río San San, 6km north of Changuinola. Get here on the bus bound for Guabito–Sixaola on the Costa Rican border. Tours are priced for groups of two.
There's a visitors center at the beach at the mouth of the Río San San that has displays on wildlife as well as a manatee-viewing area.
