Nice beach, with life guards. Good starting point for the trail heading to the hidden beach and the colored beach.

The Hidden beach, popular anyway, swimmable most of the time (any way not every day please use caution). The trail to get there add some charm to this beach.

Make sure that you get there early, wear double socks and take water with you. If you are coming from the lighthouse to "El bosque seco", make sure to take the Rocky trail.

Don't rush in the beginning because when arriving by the lighthouse there's a good hill both ways.
