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.

Iberian sanctuary in the municipality of Cabrera de Mar (Maresme). It is located in an area of Montcabrer that is difficult to access. It has a double entrance, in front of which a large number of offerings have been documented (about 50,000 ceramic fragments), consisting essentially of various types of tableware, amphorae, miniature votive amphorae, perfume containers, ceramic replicas of bovine horns, terracotta heads of Demeter and some coins. It was frequented from the 4th century BC until the turn of the century, with a special intensity in the period between 125 BC and 50 BC.
