It's a megalithic tomb, approximately 5,000 years old, discovered in 1997 and restored in 2006-2007. Located in the heart of the Montnegre i el Corredor Natural Park, it's easy to miss, but it has a history: it belonged to a Neolithic community that used it as a collective grave. Interestingly, remains of the tumulus that covered it are still preserved, which is unusual, and its orientation seems related to astronomical events, like other dolmens in the area. It's an archaeological rarity in the middle of a prime cycling area, perfect for stopping and reflecting that humans once walked this path... but without helmets.

They've now built a staircase to access the Dolmen... With this staircase, just a few meters long... It seems they'll save the site from erosion... Sometimes the conservation and environmental councils are pitiful... It seems the only ones degrading the paths... are hikers and bikers... When we're fed up with seeing how the water destroys the paths to the point where we can't pass... 🙃

"Until the middle of the 20th century, this place was one of the most emblematic of the municipality, used as a tourist and summer resort. It was a place of recreation very frequented, both by the people of Dosrius and by summer vacationers, where "I used to go there for a walk, to have lunch and to chat. Nowadays, however, the situation has changed drastically. The water is not drinkable and its condition is more than regrettable, being even flooded. which obscures the memory of its glorious days."

Isolated structure and scaffolding between two rocky outcrops (or slopes) formed by the area's own terrain. The water gushes out naturally through a metal spout embedded in a wall built of stone, attached to the slope of the western side. The water falls into a small channel that is connected to a rectangular pond built with bricks. In the center of the pool wall is a recess that lets the water pass into a small rectangular sink made of four bricks. From this sink there is a rectangular channel, also built with bricks, which leads the water to a modern drain. On the slope of the south side there is a rectangular stone panel with the following inscription: "FONT DEL SOT FERRUGINOSA". In front of the fountain is a small esplanade covered with gravel and two concrete benches for sitting.

It belongs to the Montnegre Park and almost all the paths can be done either on foot or by bike (the dolmen path is quite broken "stones")

It is a large granite block located between Turó de Montalt (596 m) and Turó del Mig (550 m), a hill where the municipal limits of Arenys de Munt, Dosrius and Sant Vicenç de Montalt meet. Of the two stones, the smaller one has an engraving that seems to represent a horseshoe, although the meaning is unknown. It could be, for example, a mark to delimit the old parishes. Granite is a hard rock, with a granular texture, which in the Maresme has been used for construction. Fresh granite is known as "snake's eye" as it is made up of a black mica which, in contrast to the other components, is reminiscent of a snake's eye. In this environment and during the next section of the route, we will find small accumulations of granite blocks, disordered, heterometric and rounded, which accumulate in a horizontal or slightly inclined relief. These capricious formations have their origin in weathering. Later, the rainwater dissolves the feldspar and the large initial rock cracks and gives rise to rounded shapes and a kind of sand, called "sauló" in Catalan.

El Montalt is a mountain belonging to the Catalan coastal range, within the Sierra del Corredor and the protected natural area in which it is included. A few kilometers from the coast, the top is surrounded by forest. A common point to face the final meters of ascent is the Coll de la Ferradura, a pass located to the northeast. It is a crossroads of different paths and forest tracks and, from this point, the path to the summit is narrow and has a very steep slope. The northern slope enters completely into the natural park, with different plateaus, other peaks and the Creu de Rupit, an outstanding cross in the middle of the path. To the northeast is the Sanctuary of the Corridor, with a car park and a tourist service office. From this point, through forest tracks, To the south, we find two towns, Sant Andreu de Llavaneres and Sant Vicenç de Montalt, well connected by tracks and paths. In the same way possible starting points for the ascent, to the west is the municipality of Dosrius and its population center of Canyamars, while to the east is the town of Arenys de Munt. On the other hand, the first stage of the Camino del Norte, or GR 83 long-distance path, which begins in the town of Mataró, passes very close, along its northern slope. Its top houses a geodesic vertex and a mailbox, offering magnificent views of the entire Maresme coast.
