Getting There & Away
If you're coming on a day trip from Medellín, it makes sense to climb Piedra del Peñol before venturing onward to Guatapé, as it can get cloudy and rainy in the afternoon. Buses to and from Medellín (COP$13,500, two hours) run about once an hour. Colectivos shuttle frequently between the turnoff to Piedra del Peñol and Guatapé (COP$2000, 10 minutes) or you can take a moto-taxi all the way to the entrance (COP$10,000).
The last bus back to Medellín is at 6:30pm on weekdays and at 7:45pm on weekends and other peak periods. If returning to Medellín from Guatapé on the weekend, be sure to buy your return ticket immediately upon arrival as buses fill up fast. The ticket office is at the Terminal de Transporte on the waterfront.
