This open cave entrance lies at the base of cliff, just to the right of a sinking stream. Stooping passage reaches a squeeze which has been passed and needs a hammer and capping to continue. The sinking water is not seen in the cave. The cave was surveyed in the summer of 2003.
Beyond the cave entrance, in a bouldery area below the cliff, strong draughts emerge from narrow joints. After the successful entry into the underground streamway through site 1930, 50m away up the steep banking, an alternative entrance was engineered under the cliff where a voice connection was initially made.
The main cave system is called Sumidero de Cobadal although site 553 is not an entrance (yet). The description is found under site 1930.
