La "Vasenilla" gives its name to a deep depression and to very inclined walls, located on the sea at the coastline. This formation is a big example of dolina of collapse, typical of limestone.
Is situated a few meters from Falla del Moraig, to the left of the path that leads up to it. The dolina keeps inside numerous fallen lumps of rock in large dimensions. It is a circular morphology with vertical walls and currently is connected to the sea, but still has not been captured by it. When this occurs, it will form an incoming in the cliffs face to develop a small cove (the dolina of collapse are one of the causes of formation of bays).
