A modest peak in Pla de la Calma, used by shepherds as a natural lookout point: from there they could see when the fogs descended from Matagalls, and the whistling of the wind in its small hollow signaled impending bad weather. The slate of the hill bears marks of use by old charcoal burners and muleteers, indicating that it was more of a practical crossing point than a refuge. A simple place, yet rich in historical significance.

More than just a place where people lived, this site stands out because it doesn't quite fit the classic settlement pattern of the area. Its location, nestled between rock and forest, suggests it wasn't a permanent settlement, but rather a site used at very specific times: seasonal migrations, hunting trips, or gatherings of small groups. A unique feature is that the remains of highly fragmented occupations have been documented at this location, suggesting it was a "ritual passage" rather than a long-term encampment. Some scholars even propose that its irregular layout among the rocks could indicate symbolic activities or territorial markers, something uncommon in other sites in the area.

A small cave hidden in a crevice of Montseny, damp and cool even in the height of summer. Its name comes from the constant croaking of frogs from the nearby stream, which seem to guard the entrance at dusk. Locals say that during storms, forest animals would take refuge inside, and that a hiker once found an old, rusty lantern hanging from the rock, as if someone had left it there to return.

Another natural and magical gem of the area. Don't miss the prehistoric-style clay carvings by a contemporary street artist. Some say that ancient peoples used the stone in initiation rituals: young people who passed through the rock were "born again" as adults of the clan. It is said that if you passed through the hole, especially children or pregnant women, you were cured of illnesses or protected from spirits. It was like a kind of "magic door" between two worlds.

This cave, inhabited in prehistoric times, contains remains that demonstrate its use in the Neolithic or Bronze Age, such as stone tools, pottery fragments, and evidence of fire. Its strategic location, hidden but with good visibility of the surroundings, made it ideal as a refuge or stopover. Today, for cyclists like us, it's an excellent shelter in case of rain or to enjoy breakfast in the shade, thanks to its peaceful and protected location.

The "Pedra de Les Orenetes" (Swallows' Stone) is made up of a large granite block about 8 m long, 3 m wide and 3 m high, which has been heavily eroded. The basal part shows several cavities, one of which is a medium-sized shelter, which is the main area of the paintings. From this concavity, through which the block can be crossed from below, other concavities and eroded points with pictographic representations continue to the right. These correspond to curved, serpentine strokes, points, female figures, cruciform figures, bars, finger marks, anthropomorphic forms, quadrupeds, branch-shaped figures and human representations, as well as remains of pigment that are difficult to interpret. the schematic-semi-schematic to the stylized and naturalistic), chromatic (reddish, reddish-brown, reddish-orange and yellowish-orange) and techniques (fingering, simple stroke and flat ink) as well as a diverse degree of erosion that seems to indicate a process with superimpositions and diverse phases, some of which seem to be related to those of the Cogul shelter.

It is a cave formed by two large blocks of granite on top of which rests another block that acts as a cover, with two chambers distributed on two different levels. The lower chamber is composed of a stone of two sides, quadrangular, which was located in the center. No materials were found in this room. In the upper chamber, three burials were found with badly decomposed bones. Ceramic fragments were found in all of them. In the first there was a flint knife, an arrowhead of the same material with a peduncle, and a plate of light green diorite (143 x 55 x 7 mm.). In the second burial, two flint knives, a flint arrowhead and a rectangular light green diorite plate (78 x 37 x 8 mm.) were found in the third, a flint knife and arrow. When sifting the soil inside the cave, four flint arrowheads, a piece of greenish-colored silicate perforated round necklace, and two flint knife fragments were exhumed. It seems that cardiac material was also found in this coat. Therefore it can be said that it is a collective sepulchral crypt from the end of the Chalcolithic and the beginning of the ancient bronze. It can be considered a type of burial that coexists with the final stages of the megalithic phenomenon.
