This scenery was generated in the Quaternary period, about 25 million years ago. A special feature about this dune field is that it is made up by ancient sandhills that “hang” over sea terraces separated by a rocky cliff.
As far as their geological aspect is concerned, they are considered a unique site as various climatic, petrographic, hydrographic, topographic, oceanic and fitogeographic factors -which may not be reproduced today- took part in their formation. Such is the importance of the Concón dune field that on August 5, 1993, it was declared Sanctuary of Nature.
Going up this dune field is an experience by itself. At first, it is somewhat steep but as we gained height the dune tended to become flatter. As we toured around, we managed to appreciate various prints made by birds, mammals and reptiles that dwell the area.
There are people who assert that this land is the last vestige of the florid desert in Northern Chile.
The hike became more intense. In this kind of unstable land, it is ideal to go up in a zigzagging pattern. As we reached the top of the dune, we set our eyes on the endless horizon, which seemed to hold hands with the sea. Watching the vastness of the sandhills made us feel as if we were immersed in a large desert.
After a few seconds of beholding, we toured around several nooks in the dune field and we began to go down. In the distance we could make out some youths practicing sandboarding on a steep sand slope. Undoubtedly, the sanctuary of nature in Concón has become a living territory for dwellers and visitors to Concón, Reñaca and Viña del Mar.
As we went down the large dune, we learnt that there are significant economic interests to change this natural sanctuary into a real estate area to build apartments overlooking the sea. Let’s hope, for the sake of its fragile ecosystem, that everyone interested in its preservation may get together in a joint effort to foster the appropriate development of this zone and thus guarantee its permanence as geological, ecological and social heritage. Our children and the children of our children will appreciate it.
It depends on the time you will spend in the area. You will need at least 45 minutes to go up.Difficulty
