Depending on your experience, Madidi National Park in Bolivia could be something from your wildest dreams or most terrifying nightmares. Lush forests and flowing rivers make this park a hiker's fantasy, but it has the potential to turn deadly in the blink of an eye. Flesh-eating bacteria and murderous wildlife are just some of the obstacles that stand in your way.
We're honestly not joking about the murderous animals. Within Madidi lives an infamous pack of wild pigs that will attack humans and literally rip them to shreds. Even if you manage to elude these horrifying creatures, more danger awaits. A small cut on your finger could be infected with parasites within minutes, making a fairly run of the mill injury the beginning of your untimely death. The Amazon is a natural wonder, but is it worth your life?
