These caves are located on the right bank of the river Segre, near Rubió, on scarp land belonging to the sierra of Mosquera (Spain). They are about 50 m above the level of the river, where there are a series of cavities and shelters. Paintings have been identified in four of these caves.

The group consists of four cavities containing paintings: the first two –which are difficult to get to- are genuine concavities, while the other two –which are more easily accessible- are shallower walls that offer little protection. In all, 18 figures have been identified.

Aparets I
This is a 2.4 m wide cavity, is 4.10 m deep and 3.60 m high and runs towards the SW. The paintings are located in the central area, at the back of the cavity. It is only possible to clearly identify two figures with a schematic ramiform drawn with a simple stroke technique and some remains of pigment. Both figures are red in colour.

Aparets II
Going on another 10 metres to the right, there is a second concavity containing pictures. This has a very particular form: there is a type of straight platform that ends in a rounded vault which contains the most unique figure. Eight different figures have been identified on the two sides, two encircled elements (one of which has protuberances), lines, ramiforms and remains of pigment. The style employed is schematic, the technique consists of simple strokes and there are different colours (red, reddish chestnut-red, pink, reddish-orange and black).

Aparets III
This site is 16 m to the right of Aparets II and about 10 m to the left of Aparets IV. Five anthropomorphic figures have been identified and also remains of pigment: the style is schematic. The technique employed is that of simple strokes and the predominant colour is red, although there are also remains of reddish-chestnut pigment.

Aparets IV
The last of the shelters is located about 10 m to the right of Aparets III, though at a lower level. It is also a small concavity that offers little shelter and houses three painted elements corresponding to an anthropomorphic form and remains of pigment. The style is schematic, the technique used is that of simple strokes and the colours are red and reddish-orange
