How to get there?

The chances are you’re in Medellin.

Take the metro or taxi to Caribe Station. From there go to the North Bus terminal (Terminal de Transportes Norte).
Buy a ticket to either Guatape or El Peñol at the ticket booths. There’s one or two bus companies that go there. It should cost between $12,000 – $14,000 COP each way or around $4 USD. Total: $25,000 COP = $8.00 USD.
The bus will stop for passengers along the way, expect between 1 ½ to 2 hour drive.
You can either get off at the base of El Peñol or you can go to Guatape if you plan on exploring the town.
