We enjoyed traveling by bus in Panama: the system works! All buses are ponctual, comfortable and reach the most outlandish destinations! Leavinf from Albrook terminal in Panama city, we first made our way to Chitre, in the Azuelo peninsula...(Pacific side). This region is not very touristic; in the Carnival season in February, the fiestas attract mostly Panameans. At other times, it is really quiet, with people working in fields, or milking their cows for Nestle!
