Crossing this mountainous bridge definitely requires a lot of courage but if you do it, you will be rewarded with a spectacular view of the mountains and a chance to look down on clouds like a god. One more thing you have to be aware of, though, is that the trail that leads to the bridge could be more frightening.

Discovering one of the most diverse tropical forests in the world is definitely better if you are surrounded by trees. However, watch your step because there are missing boards and you might fall through the gaps. Ending up on ground of the rainforest is not fun.
