Mocoa, Putumayo, Colombia: “El fin del Mundo” in Colombia is small cluster of waterfalls outside of Mocoa in the jungle. Mocoa is a fairly nondescript town. It’s a smaller version of Iquitos.  

It’s a pleasant hike up a couple of hills and across two rivers. 

  
The local story behind the name is that the local children would run through the jungle for what felt like an eternity and get to the top of the waterfall. The ground would fall away and they said it was like reaching the end of the world. 

Apocryphal or not it’s a good story. And while it is a nice hike the people who named the waterfall obviously have not been to Iguazu.
