Caves and potholes in Rubió

Rubió, in the Anoia, sits on an interior plateau of the comarca, a rural and sparsely populated territory of transition between the Catalan central depression and the first foothills of the coastal pre-range (serralada prelitoral). This gentle relief, though with more rugged limestone sectors, contains a small set of catalogued cavities that form part of the speleological heritage of the Anoia.
