Colombia
The Camino Real to Guane is an ancient paved track leading down the precipitous slope to the east of Barichara, and though fields and woods all the way to the colonial village of Guane. It's nine kilometres of good walking, and in Guane you can get a huge meal for about five quid (at the restaurant in the road leading up on the left hand side of the church), wander around the village, and try chicha (alcoholic Horlicks) and sabajon (a milk-and-liquor mix). It's not a challenging trek, it's just a great day's walking.
