Name: Cueva Bolado (Las Herrerías, blacksmiths)
Location: 2.5km S of Llanes (3.5km by road). From the Llanes–La Pareda road, turn left about 0.6km after crossing the main N634 road.

Map: Porrúa (32-III)
Survey: see artepaleoliticoenasturias.com/2014/01/04/las-herrerias/ » (this also mentions the name ‘Bolao’ and suggests that that name refers to a different nearby cave).
Description: Easy walking cave with crystals, at the end. One side passage is gated off, presumably has paintings or other archaeological interest.
