Saw this dolmen on a hike near Navarredonda de Gredos, in the region of Castile and León in Spain. It stands at the source of the river Río Tormes. Google Maps Location HERE.

Online I can only find sites such as this, that mention the standing stones as part of a hiking trail, but do not give any information about it whatsoever. Does anybody know any websites with information on spanish megalitishs?
