Barichara
The little colonial village of Barichara makes a good day trip. There are buses going every hour and leave from the corner of Carrera 11 and Calle 15. From Barichara it is a lovely 2 hour walk along an historic Spanish road to Guane. Buses return to Barichara several times a day. It is recommended to walk Barichara to Guane and not the other direction, since that would be entirely uphill.
