After the lost city, I spent a day visiting Tayrona Park. A 45 minute bus, a 15 minute shuttle, a 2 hour walk, and a hammock rental later, I was hanging out on one of the most beautiful beaches in South America!
From there I headed to Medellin, and started with a day trip to Guatape. A beautiful town outside of Medellin with an unusual rock formation that offers amazing views of the area.
I was really impressed by Medellin. It's changed a lot since the time of Pablo Escobar and I can see why travelers who come end up staying (sometimes indefinitely!). The people are so kind, the city is clean, and the public transportation is impressive. It's also got great nightlife and tons to do. I think I may go back!
