The largest natural park inside Medellin's metropolitan area — a steep, forested hill that rises two hundred metres out of the valley floor, ringed by city on every side. Reach the top by a winding tarmac path (about forty minutes' walk) for a 360-degree view of the entire Aburrá Valley. Bring water and don't go alone after dark.
The forest is regenerated rather than original but holds a surprising amount of birdlife. Best in early morning when the air is clear.
