The Blue Mountains form the spine of eastern Jamaica, rising to 2,256 m at Blue Mountain Peak — the highest point in the Caribbean outside Hispaniola. They're named for the blue mist that hangs over them in the mornings, visible from Kingston below.
The mountains are the source of Blue Mountain coffee, grown on small farms between about 900 m and 1,800 m altitude. The combination of altitude, rich volcanic soil, cool temperatures, and high rainfall produces beans that command some of the highest prices in the world. Most of the genuine crop is exported to Japan.
The main base for the mountains is Mavis Bank, reached by a winding road from Kingston through the Papine suburb. From Mavis Bank it's a further rough drive (4WD recommended) to the trailheads. The ascent to Blue Mountain Peak is usually done overnight, departing around 2am to arrive at sunrise. The trail passes through montane forest full of ferns, mosses, and tree ferns.
The mountains are also home to the Holywell Recreational Area, a forest park about 1,000 m up the main road from Kingston with cabins, camping, and short hiking trails.
