The Cueva Costazu is a well known cave, used for years as a cheese cave. Well known to the Portudera shepherds. Located in the area known as El Costazu Gobio - an area very close to the Vega de l'Engraneu


Entrance easily located, in a rocky slope close to a small meadow


Entrance leads to chamber with the remains of cheese racks. At the end of the chamber are 3 options
The first, and most obvious, is a descending passage, which reduces in size to become impenetrable (-10m)
The second option, up a small climb narrows before increasing to small area with many formations, but with no possibility of continuation.
The third and main option is a small low, and slightly upward, passage, after which a sudden change of direction, leads to a larger gallery.
At the end of the chamber, and after another change of direction, a new chamber, full of mud, continues, until a small streamway is encountered. This is small and short to an impenetrable rift (-12m),
