The Zapata Peninsula is Cuba's largest wetland — 4,520 km² of mangrove coast, freshwater marsh, and saltwater lagoon occupying the southern bulge of Matanzas province. It is a place where the tidal signal matters not just at the shoreline but 15–20 km into the interior, where coastal lagoons connect to the sea through a web of mangrove channels that the tide fills and empties twice daily. The tidal range along the peninsula's coast is Caribbean microtidal: mean spring range 0.2–0.4 m. On the open mangrove coast that faces the Golfo de Cazones to the southwest, this translates to a modest change in water level at the shoreline. But the geometry of the lagoon system behind the coast amplifies the effect. The flood tide pushes saline water up to 5 km into the mangrove channel labyrinths, raising salinity gradients, oxygenating the deeper channels, and triggering movement in the animals that depend on that tidal pulse. Manatees (Trichechus manatus) use the flooded mangrove edges during high water to feed on submerged vegetation; they retreat to the deeper lagoon channels on the ebb. Spotting them requires patience and a quiet approach by flat-bottomed boat — engine noise carries far in shallow water, and manatees here are wary. Las Salinas Wildlife Refuge occupies the eastern shore of the Bahía de Cochinos (Bay of Pigs) — it is one of the most significant bird concentration points in the Caribbean. The site is best known for its greater flamingo population: flocks of up to 2,000 birds use the saline flats and shallow lagoon margins, and their movements track the tide. On the flood, they wade into the newly inundated shallows to filter-feed on invertebrates stirred up by the incoming water. From approximately 07:00 to 09:00 on a rising tide, the flocks are most active and most accessible from the observation tracks. The Cuban crane (Grus canadensis nesiotes) is present year-round; roseate spoonbill, wood stork, and tricoloured heron are among the other species recorded. For serious birdwatchers, Las Salinas is the most productive single site in Cuba. The Ciénaga de Zapata National Park, which covers the bulk of the peninsula, holds Cuba's most intact freshwater wetland ecosystem. The park's interior lagoons — Laguna del Tesoro being the largest — are accessible by boat from the village of Guamá, where a tourist facility on an artificial island serves as a base. The Central Australia crocodile hatchery station, on the road into the park from Jagüey Grande, runs a Cuban crocodile (Crocodylus rhombifer) breeding programme — captive animals from hatchling to multi-metre adults are held in open pens, and the facility gives the clearest close-up view of the species outside a zoo. The endemic bee hummingbird is present in flowering areas throughout the park; the best chances are around the flowering trees near the park road in the early morning. Fishing is the other reason people travel here. The tidal channels of Laguna de las Salinas and the estuary system east of the Bay of Pigs hold tarpon (Megalops atlanticus) — large, fast, and strong. Fly-fishing for tarpon in these mangrove channels is an organised activity with licensed guides operating out of the Las Salinas area. The best fishing occurs on a rising tide, when tarpon push into the shallower channel sections to hunt. A 20–30 kg fish is realistic; specimens over 50 kg have been reported from the lagoon system. Bonefish are present on the flats at the bay edges. Access requires a local guide and permission to enter the refuge; independent access to the best water is not permitted. For paddlers, the mangrove channels of the Ciénaga offer a different kind of experience: narrow, shaded, biologically dense. The tidal current in the channels reverses over a 6-hour cycle; paddling with the flood in the morning and with the ebb in the afternoon allows a return trip without paddling against the current. Bring water, insect repellent, and a GPS track — the channels branch frequently and orientation is difficult without reference points. The road access to the peninsula runs south from Jagüey Grande through the sugar-cane country of Matanzas's interior. Fuel and provisions are limited inside the park; stock up before turning south.
