The “desert” actually is a strange geological formation in the Cundinamarca Sabana. You reach by car from Bogotá passing by Nemocon city and driving some additional Km where you can leave the car for a 40 min walk, or less if you bring your bike, till the entrance to the place. From there you will be guided through the place where you will see the formation. The guided tour itself will not last more than 30-40 min but it really worth it. It is not difficult so it is ok to go with small kids as well.
