Portland, with its capital town Port Antonio, is a parish located on Jamaica’s northeast coast. It is situated to the north of St Thomas, and the east of St Mary in Surrey county. It is one of the rural areas of Jamaica and is known for its great beaches.
The parish is situated at latitude 18°10′ N and longitude 75°27’W. It extends from the highest peaks of the Blue Mountains, 2,256 metres (7,402 ft) above sea-level, down to the north coast, and is noted for its fertile soil, beautiful scenery, and fine beaches. The parish lies in the direct path of the northeast trade winds, and the Blue Mountain ridge to its south traps the moisture causing the parish to have the highest rainfall in the island. Port Antonio, its chief town and capital, has two harbours, the western one being sheltered by a small islet, Navy Island. Portland covers an area of 814 square kilometers, making it Jamaica’s seventh largest parish.
The parish has a variety of complex landforms; the entire coastline is dotted with caves, bays, rivers, waterfalls and hills. There are fourteen caves, which include those at Buff Bay, Orange Bay, Hope Bay, Port Antonio, Boston Bay, Long Bay, Innis Bay and Nonsuch. There are also 17 rivers which form a network throughout the parish. The largest are the Rio Grande, Buff Bay and Hectors Rivers.
