May Pen is the capital of Clarendon parish, situated on the south coast highway between Kingston and Mandeville. It's a busy market town and road junction rather than a destination in itself, but it serves as a gateway to the Milk River mineral baths — reportedly the most radioactive therapeutic waters in the world, though the radioactivity level is said to be harmlessly low — and to the scenic Canoe Valley Wetlands, one of Jamaica's important bird areas.
Most travellers pass through May Pen without stopping, which is understandable. If you have time, the central market on a Saturday morning gives an unfiltered view of how a Jamaican country town actually operates. South of town, Halse Hall is one of the best-preserved 17th-century great houses on the island, and the Denbigh showground hosts Jamaica's biggest agricultural fair every August.
