Fin del Mundo (meaning: End of the World) is a natural reserve and extremely beautiful waterfall, just a few kilometer outside of Mocoa.
Take a "Collectivo" for 1000 COP to the entrance and cross the bridge to start the trek. The Entrance fee is 2000 COP. After roughly one hour walking (mainly uphill) you'll reach the top and come across several pools (bathing is possible) and many smaller waterfalls. Also a restaurant is build there beautifully in a cave where you can order food and drinks. The actual "Fin del Mundo" is at the very end of the trek and you'll arrive on top of the fall - looking down approximately 70 to 80 meters!
A small path to your right leads down all the way to the falls bottom (great spot for making pictures) but its not very easy walking and sometimes slippery - so be careful! Once on the bottom you need to follow the same path up again.
To return to the bridge you'll have to follow the same way back which you came from. But since it's only going down, it will be quite fast.
Hornoyaco (Waterfall): (or: "Cascada del Hornoyaco") is located only a few kilometers outside of Mocoa town. It's a natural paradiese in the mountain range Churumbelo with an amazing lagoon at its bottom. The trek up to the fall is great for spotting birds, strange-looking insects and pretty butterflys. Hiring a Tourguide for this trek is not necessary!
There are several options of how to get to the Hornoyaco. The cheapest way is either hitchhiking (which is certainly safe around Mocoa) or you take one of the many "Collectivos" (Pick-Ups) which will charge you 1000 COP from Mocoa to the starting-point of the trek. Taxis are avaible as well but not really necessary (unless you're in a rush and need to get to the fall fast) and considerably expensiv! Of course you could also just walk. Ask the people for the direction to Fin del Mundo, which is better known than the Hornoyaco. Along the way from Mocoa to Fin del Mundo is a sign claiming "1 km to Hornoyaco" and indeed, after about one kilometer you'll reach the starting-point of this trek. But from here to the actuall falls it's still a little walking (approximetaley one or two hours).
The Trek: Cross the big bridge to the other side of the river and follow the biggest path (a bit to your right). Very short after the bridge you'll encounter multible paths leading in all kinds of directions - just stay along the biggest (which is also the only one with build in logs on some parts, to make walking easier). After a little while you have to cross a little river and soon see military fences to your right and left. Shortly after you'll see a little farm to your right with a little fish pond in front of the house. Further up there are two more smaller bridges to cross. Now the way itself goes mainly uphill and it can be very hot and humid at times. So be sure you only carry the necessitys and enough water! The main path splits almost at the end of the trek into two directions: One leads higher up onto a wide hillslope without (almost) any trees; the other way goes to your right. Choose the one to your right and soon, at another intersection, you'll see a sign saying "Hornoyaco Falls ->". From here you can't miss it anymore. Follow the arrow on the sign (pointing to your right) and carefully "climb" down this small path. This bit can be extremley slippery especially during or after rain! It's a narrow and steep path, there are lots of roots from trees and lose rocks and water going down on the track! After only a few minutes and a couple of hundred meters you'll reach the bottom of the Hornoyaco fall and it's amazing lagoon. Put on your bathing suit and go for swim!! Now you'll know, that this trek was worth it!
There are some spots were people made campfires and it also should be possible to camp at this location but please ask locals first and get sure you'll leave the place clean! To go back to the main street and back to Mocoa town, you'll have to follow the same way back were you came from. Since it's from here mainly downhill it will be very fast!
Whenever you feel uncertain whether you're going the right or wrong way, simply ask the locals about the way (especially men with groups of horses are seen many times). This trek is not very common for tourists and the locals are more than happy to help you out!
Things you ought to take with you: Enough water, some food, bathing cloth and towel, camera.
