This small fishing village hosts a small community of guides specializing in bird- and dolphin-watching tours through the local mangroves and estuary. The Ecoclub Los Delfínes (Dolphin Eco-Club) runs a small museum at the docks here, with the skeleton of a bottlenose dolphin, as well as various displays about the local coastal ecosystems. From here, tours head out for anywhere from 90 minutes to 3 hours. Along the way, there's a good chance you will see some bottlenose dolphins. Even if you don't, the bird-watching is excellent, and the scenery is beautiful. Most tours stop at a small island that is both a local crab-processing spot and a nesting ground for thousands of magnificent frigate birds. Most tour operators in Guayaquil offer day tours here. Hamaca Tours & Expeditions (tel. 04/2314-797; www.hamacatours.com), in particular, specializes in this tour.
