The Blue Mountains are the longest mountain range in Jamaica. They include the island's highest point, Blue Mountain Peak, at 2256 m (7402 ft). From the summit, accessible via a walking track, both the north and south coasts of the island can be seen. On a clear day, the outline of the island Cuba, 210 km (130 mi) away, can also be seen.It spreads in 4 parishes: Portland, St.Thomas, St Mary, St.Andrew
As one of the longest continuous valley ranges in the Caribbean, the Blue Mountains dominate the eastern third of Jamaica, while bordering the eastern parishes of Portland, St. Thomas, St. Mary and St. Andrew to the south. Part of the Blue Mountains is contained in the Blue Mountain John Crow Mountain National Park established in 1992, which is maintained by the Jamaican government.
The Blue Mountains rise to its elevations from the coastal plain in the space of about 16 kilometres (9.9 mi), thus producing one of the steepest general gradients in the world. This forms cooling relief from the sweltering heat of Kingston visible below. Their summits rise and fall for 24 miles and span 14 miles at their widest point. The temperature decreases from around 27°C (80°F) at sea level to 5°C (40°F) at the Blue Mountain Peak, just 16 km (9.9 mi) inland.
The island's average rainfall is 1,960 millimetres (77 in) per year. Where the higher elevations of the Blue Mountains catch the rain from moisture-laden winds it exceeds 5,080 millimetres (200 in) per year with some areas recording totals of more than 7,620 millimetres (300 in).
Flora and fauna
The Blue Mountains climatic diversity has led to the growth of diverse and lush vegetation including towering trees and more than 500 species of flowering plants.
The mountains are home to the world's second largest butterfly and the largest in the Americas, the Homerus swallowtail (Papilio homerus). The Jamaican Coney (Geocapromys brownii), a type of rodent, and the Jamaican boa (Epicrates subflavus) are also found there. More than 200 species of birds live in the Blue Mountains of which most are exclusively neotropical.[clarification needed]
In past years when Jamaica's economy was dominated by plantation slavery, some enslaved people known as Maroons escaped to the Blue Mountains and live independently.
Today, the famous Jamaican Blue Mountain Coffee, which commands premium prices on world markets, is cultivated between 2,000 and 5,000 feet above sea level, while higher slopes are preserved as forest. Hagley Gap and Mavis Bank are farming communities located on Blue Mountain with Hagley Gap being closest to Blue Mountain Peak. Both towns rely upon the area's rich soil for growing coffee.
