St CatherineSt Catherine is located at 18°N 77°W. It is bordered by St Andrew in the east, Clarendon in the west, and by St Mary and St Ann in the north. It has an area of 1,192 km², making it one of Jamaica's largest parishes and it is one of the fastest growing parishes in the nation and has the largest economy out of all fourteen parishes. Except for the Hellshire Hills near the coast, the south of the parish is virtually flat. The central and northern sections are very mountainous, however; the northern border is on Mount Diablo, which crosses over into St Ann, the highest point being 686 metres (2,251 ft). A plain of approximately 230 square kilometres (57,000 acres) occupies the southern part of the Rio Cobre basin. The Rio Cobre is the only river that runs along the southern plain. It provides water to irrigate over 73 square kilometres (18,000 acres) on the plain. Out of all the parishes (with the exception of Kingston Parish and Saint Andrew Parish) Saint Catherine shows the most potential for urban development. With its good water resources, virtually flat landscape, and nearness to the capital, it could possibly be one of the Caribbean's major urban areas in the next few years.
- Jamaica's emancipation Square can be found in Spanish Town. This is the only Georgian square in Jamaica. Kings House and the House of Assembly on the west and east sides, respectively, were erected in 1762. The Courthouse was built in 1819 and used as a chapel and armory with the Town Hall upstairs.
- The Rio Cobre River and Gorge is one of the largest in the island. Sinking at a place called River Sink at Worthy Park, it runs underground for nearly six kilometres, then surfaces at River Head Grand Cave in St Thomas-in-the-Vale. Before entering the gorge it is joined by a number of tributaries, such as the Thomas River, the Rio D'Oro and the Rio Pedro. In the early 1770s, a road was opened through the gorge. The Flat Bridge was originally constructed of logs, which were washed away in a flood. The present bridge was built and it has withstood countless floods. A marker can be found, which shows where the water rose to over 25 feet (7.6 m) above the bridge in 1933. An apocryphal story is that at noon, on every Good Friday, for a short period of time the ghosts of all the slaves who drowned in the river can be seen.
- Caymanas Race Track, Jamaica's most famous race track, is in St Catherine.
- St Clair Cave, one of Jamaica's more famous caves, is found in the parish. This large, complex cave contains one of the most notable bat roosts on the island, and is one of the few known historical sites for the possibly extinct bat, Phyllonycteris aphylla. Because of the biological importance of the system, and the inherent dangers involved in exploring it (i.e. noxious gases, histoplasmosis, Cutaneous larva migrans, difficult footing), casual visitation is discouraged.
