Its location is an Edenic series of steep, lush hills dense with tall trees and bordered by the green and red berries of low-lying bushes. Those same bushes are where hundreds of workers in pink plastic aprons, tramping the muddy roads in their gumboots, harvest coffee beans for the Don Paco brand. El Quetzal is a 170-hectare (420-acre) coffee farm that could be regarded as a model for the future. In line with the paternalist tradition, all the workers live on-site in individual homes, and there is also a library and a school. The estate has its own hydroelectric plant, and one of the white clapboard sheds holds a bio-digester churning out methane for re-use. Troughs and pipes mark the harvesting unit where the beans are de-pulped. In the pride of place is a hacienda-style house with a large white veranda holding a long line of baseball caps. There are rooms with bunk beds here, and accommodations can be arranged in advance for self-sufficient groups for approximately C400 a bed. Needless to say, the morning coffee in the mountain air is excellent.
