The coffee town of Andes in the department of Antioquia is almost three hours from Medellín by bus. It’s a stop along the route to the more popular, more beautiful, and more tourist-friendly Jardín. There’s not much reason to stop in Andes.
Andes has a nice wide open plaza with a beautiful fountain.
The plaza is surrounded by a couple colonial buildings and filled with tables where locals sit and enjoy a coffee or drink with their friends and family.
The church on the plaza is also nice and worth a look inside.
A couple companies pass through Andes on the way to Jardín from Medellín. Rapido Ochoa and Transporte Suroeste are the ones I’ve used. There is a main bus station where buses from Medellín stop and another one near the entrance where buses and taxis to Jardín can be found (COP$4,000 as of July 2015).
