Happy Travel Tuesday from Jamaica’s Black River. This river is located in the parish of St. Elizabeth and is one of the longest rivers in Jamaica at 33.2 miles. Its name refers to the darkness of the river bed caused by thick layers of decomposing vegetation. Over 100 species of birds have been recorded in the Black River morass. The river’s source is the Cockpit Country where it runs underground before emerging north of Siloah on the southern fringe Cockpits.
