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 of Cuba, 210 km (130 mi) away, can also be seen. The mountain range spans four parishes: Portland, St. Thomas, St. Mary and St. Andrew.
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 and John Crow Mountains 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 the city of Kingston, visible below. Their summits rise and fall for 38.62 kilometres (24.00 mi) and span 22.53 kilometres (14.00 mi) 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. This is the most well-studied remaining population of the endangered butterfly. The Jamaican Coney (Geocapromys brownii), a type of rodent, and the Jamaican boa (Chilabothrus subflavus) are also found there.
In past years when Jamaica's economy was dominated by plantation slavery, some slaves escaped to the mountains to live independently, where they were known as Jamaican Maroons. Charles Town, Jamaica on the Buff Bay River in central Portland, Moore Town in eastern Portland, and Scott's Hall, Jamaica in St Mary are the contemporary communities of Windward Maroons.
Today, the famous Jamaican Blue Mountain Coffee, which commands premium prices on world markets, is cultivated between 0.6 kilometres (0.37 mi) and 1.5 kilometres (0.93 mi) 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.
