Sa Roncadora

It is a long 46-metre fissure that connects the upper part of the cliff with sea level. The upper mouth is 27 metres long by a maximum width of 6 metres, it is funnel-shaped and narrows as one descends until reaching the water, where in some places it becomes impenetrable while in others it widens to almost 2 metres. From the lower lip to sea level there are 17 metres.

Entering through the sea mouth the depth below the water level reaches 12.5 metres and one finds a bedrock that blocks the way but is easily passable either by climbing over it or passing under the water (the rock only reaches 1 metre of depth); past this one can advance about 13 metres, at first narrow and progressively widening to 1.6 metres, then it suddenly narrows to 20 centimetres which make it impenetrable at least at water level.

The truth is that, descending the 17-metre shaft, the cave seems to continue below the water and with more width than at the surface, but we have no news that it has been explored.
