Camping in Parque Tayrona, Colombia

Parque Tayrona is in the Sierra Nevada, which is a 3-4 hour drive North of Cartagena. I arrive clad in brand new white sneakers and a vintage Louis Vuitton backpack in which I’m smuggling wine and Aguaardiente. I feel more than prepared for what should be a “short walk” to our accommodations. Being in good company and having done hikes before, how long could it take to hike up a few kilometers?
