First of all - it is not easy to distinguish what exactly was inscribed as Coffee Cultural Landscape - particular coffee farms, land area, towns and villages. All available maps do not show inscribed zone, there are no signs of World Heritage in the places (yet, November 2011) that is for sure inscribed as UNESCO heritage. But for sure the landscapes are spectacular although I haven't seen any difference between inscribed part and non-inscribed.
I was visiting Salamina, passing through Chinchina, travelling around Salento, Manizales, Armenia and Pereira. Those areas are either directly inscribed as WHS (Salamina, Chinchina) or located in close vicinity of Coffee Cultural Landscape. Salamina is truly remarkable (nice colonial town, sourrounded by high mountains, with lovely old houses, one the most interesting places in Colombia). Chinchina looks to be quite ordinary, like many other towns.
