Alternatively it is very interesting to visit the Centre. This center have reproductions of the most characteristic speleothems, a virtual tour of the cave through a 3D projection, panels and interpretation of all geological features of the cave and its surroundings. You can find in this page an e-booklet with the English version of the interpretation panels.
ATTRACTIONS OF THE VISIT
Its great variety of shapes and its mineralogy make the Cueva de Castañar a karst cavity that is unique in the world:
Coladas: These are formations, generally of calcite, with thick layers that reach the ground in steps.
Flags or curtains: They hang from the walls like veils and are basically of calcite.
Ribs: Vertical formations with a tubular morphology that hang from the ceiling and have a central channel through which water drops. They are of aragonite or calcite.
Stalactites: Similar to ribs but larger. They are of calcite or aragonite.
Stalagmites: They grow from the ground where drops fall from a stalactite and have a calcitic and/or aragonitic composition.
Columns: These are formed by the coalescence of stalactites and stalagmites.
Fibrous formations: These are the most characteristic speleothems of this cave; they are acicular crystals of aragonite. They develop from a central point to form very delicate fibrous-radial aggregates which are known as “aragonite flowers” (this is the logo of the Geopark).
Moon-milk: A matt white globular deposit that may have a considerable content of intercrystalline water. The minerals from which it forms in this cave are essentially dolomite and magnesite.
