Jamaican mountain range

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, 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 , 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 and span 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 inland.

The island's average rainfall is per year. Where the higher elevations of the Blue Mountains catch the rain from moisture laden winds it exceeds per year with some areas recording totals of more than .

High elevations of the Blue Mountains have a subtropical highland climate (Cfb) under the Köppen climate classification.

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). This is the most well studied remaining population of the endangered butterfly. The Jamaican coney (Geocapromys brownii), a type of hutia and Jamaica's only native land mammal, as well as the Jamaican boa (Chilabothrus subflavus) and wintering Bicknell's thrushes (Catharus bicknelli) are found here.
