The Bufones at Santiuste. Natural Monument
These are found in the most easterly part of the flat coastal plain of Llanes. Only a short distance from the beach at la Franca. These bufones are one of the most spectacular formations to be found in limestone cliffs. They are created in the cliffs next to the sea via little cracks in the limestone rock. The bufones comprise a cave or chamber in the rock that leads vertically upwards and here, under great pressure, seawater and air are expelled, due to the force of the tide. As a result howling jets of water shoot up to 30 metres in the air, a feature unique to this part of the coast.
