The Black River and the Great Morass
The island's largest wetland, a mangrove river system holding several hundred American crocodiles, entered by boat from an old port town.

The Black River takes its name from the peat bed that darkens the water, and behind the coast it spreads into the Great Morass, some two hundred square kilometres of mangrove, swamp forest and reed, the largest wetland in Jamaica and a Ramsar site. Boat safaris run upriver from the town, threading between red mangrove roots into narrow channels, and the draw is the American crocodiles, several hundred of which live here and which have become used enough to boats to approach them closely. Egrets, herons, jacanas and kingfishers work the margins. Black River town itself has a run of Georgian and Victorian buildings from its logwood-trading days. Hurricane Melissa, which came ashore in neighbouring Westmoreland on 28 October 2025 as a Category 5 storm, drove the highest storm surge on the island into Black River, took the roofs off an estimated 90% of the town's homes and destroyed Waterloo House, one of its colonial-era landmarks, so check what has reopened before planning a stop.
What you'll find
- American crocodiles - several hundred in the river system.
- The mangrove channels - narrow passages between red mangrove roots.
- Waterbirds - egrets, herons, jacanas and kingfishers along the banks.
- Black River town - Georgian and Victorian buildings from the logwood era, hit hard by Hurricane Melissa in October 2025.
When to go
December to April is drier and the water clearest. Early morning and late afternoon are best for birds and for crocodile activity, and cooler on an open boat. Trips run through the day from the town wharf.
Practical notes
Some operators feed the crocodiles to guarantee sightings, which is bad practice and has produced animals that approach boats expecting food; choose a guide who does not. Boats are open with no shade and the sun on the water is fierce. The wetland has been squeezed by drainage and agriculture. Trips are short for the price.
