The mangroves of the Rio Coto estuary contain an incredible array of wildlife: numerous species of waterbirds, howler, white-faced and squirrel monkeys, caimans and crocodiles. Our boat tour through the meandering mangrove swamp, where it is unlikely to encounter any other tourists, is preceded by a drive through the rainforest to Golfito and includes a stop at Zancudo Beach for a picnic lunch and swimming.
