Just a quick video highlighting the very steep (and very narrow) staircase to the top of El Penon.
El Penon is a huge rock formation in the middle of a lake system in Colombia. It's located about 1 hours bus trip away from Medellin.
This video was taken in August 2018 (perfect weather for those thinking about travelling).
The climb to the top of the rock is exhausting. This video shows the view from 1/3 up the rock. The view from the top is absolutely stunning.
