Cova M-20

The cave is located in Montcortès, in the Baix Pallars. From Senterada you must head towards the Pobleta de Bellveí, where you take a narrow road on the right as far as the Montcortès lake. From the E side of the lake an asphalted track leads off towards Peracalç; on reaching the junction with the track that goes to Montsor, you take this track to the right, suitable for any vehicle, and after 1.7 kilometres you reach the flat area where the cavities are found. This flat area is on the left of the track and the spot is easily recognised because the track makes a sharp bend to the right and also on the right there is a large temporary pool of water used for watering animals.

Identifying the cavities is quite complicated, since at present (2011) only the painted name is preserved in M-1 and M-11; in the remaining cavities any sign identifying them has disappeared, and the GEB gives no information about any guideline followed in order to identify them. Therefore, except for these two cavities, it is unknown which coordinates correctly correspond to each of them; it has been considered appropriate to mark the remaining cavities with coordinates located between M-1 and M-11, bearing in mind that except for M-8, which is a couple of bends before reaching the flat area, the remaining cavities are located within a radius of less than 200 metres from this indicated point; in some cases the coordinates correspond to hole entrances, but it is unknown whether they correspond to the same ones. Approximate coordinates within a radius of less than 200 metres.
