Oratory dedicated to Our Lady of Montserrat where we can see a small image with offerings of rosemary. It is located about 60 meters below the hermitage of Sant Salvador. It is usually open on the same days as the hermitage of Sant Salvador.

Spacious balma that had been enabled as a refuge in Montserrat Despite the fact that in many maps and texts it appears as a balm, we prefer to mention it as a cave, which is what it is in reality and, moreover, this is how it appears on the map of the Cartographic and Geological Institute of Catalonia. It is a fairly spacious cave, it is 16 meters deep and 45 meters wide, inside there is a small wall of stones. Josep Fatjó tells us about this cavity, "it was fixed throughout the year 1959 and on the day of the inauguration the climbing monks said a mass". In the cave there was a wall in front of wood, bedrooms with two rows of wooden bunks and logs with a capacity for about 15-20 people, there was also a firewood store and a dining room with a fireplace, all made by members of the GAM of the Barcelonès Mountain Club. The unsightly people who roam the mountains with their lack of civility have dedicated themselves to burning everything and have reduced this emblematic place to a pile of ashes.

Cavity 23 meters long by 5 meters wide. It is formed under some rocks off the cliff, hence the toponym of the landslide. Inside there is a small perennial water cistern, built in 1947, and next to it there is a chest with a fountain, which although years ago we had seen in good condition, is currently unusable. All of this favored the climbers' stay. Known since time immemorial. Mentioned in all the collections of cavities and guides of Montserrat, but of little speleological interest.

On the northern slope of the Serrat del Cabrit, there is a deep torrent hidden in the shade of holm oaks: the Coma Alta. This torrent, usually dry, descends in a SW direction until it reaches a vertical jump of 50 meters. At the foot of this jump, we find the Cova de l'Arcada. Unlike the Salnitre, the Arcada is not underground and has a small entrance. It's just the opposite: open and shallow, but of colossal size. Its monumental arch is approximately 30 meters high by 60 meters wide and 10 meters deep. Canyoning enthusiasts can access it from above, through the Torrent de la Coma Alta, abseiling to the entrance of the cave.

It was located at the head of the torrent of the same name, under the rocks known as the viewpoint of Sant Joan, about fifty meters below the hermitage of Sant Joan, a little to the right of the ravine, facing south, at an altitude of 985 meters. For the construction, a wide balma was used, in which some parts of the walls are still standing, holes to point the beams, and, above all, the important pipes worked in the rock, of considerable depth and very well distributed for water conduction. Due to its excellent orientation towards the south and well sheltered, it had a reputation for sheltering many nests, especially nightingales and blackbirds, so much so that it was known by the Montserrat Birdhouse.

The most prominent caves in the area are the Coves del Collbató, also known as the Coves del Salnitre or Montserrat Caves. These impressive limestone caves are located within the Montserrat massif. Other notable natural cavities include the Cave of Our Lady of Montserrat, a historical and religious site, and Font de l'Esllavissada, a natural monument featuring a perennial water cistern.
The caves around Collbató are prime examples of karst scenery within a rare conglomerate rock formation. You'll encounter breathtaking speleothems like stalactites, stalagmites, and columns, formed by rainwater dissolving limestone over millennia. Specific sections like El Pou del Diable are known for spectacular formations, and La Cova del Cambril o Columnes boasts impressive stalactite columns.
The caves hold significant historical and cultural importance. Archaeological findings indicate the area has been inhabited since at least 4000 BC, with Neolithic remains found within. They were historically used for extracting sodium nitrate (saltpetre), giving them one of their names. The famous architect Antoni Gaudí was reportedly inspired by the stalactites and stalagmites here, influencing his architectural works.
Yes, the Coves del Collbató are designed to be accessible for general visitors and are considered a unique day out for families. Guided tours are available to enhance the experience. While there are 244 exterior steps and approximately 500 steps inside, the paths are well-maintained for exploration.
The interior of the Salnitre Caves maintains a constant temperature of around 14°C (57°F) and a high relative humidity of 97-99% throughout the year. It's advisable to wear comfortable walking shoes and bring a light jacket or sweater, even on warm days, due to the cool and damp conditions inside.
Yes, Cova de l'Arcada is notable for its monumental arch, approximately 30 meters high by 60 meters wide and 10 meters deep. Unlike typical underground caves, it is open and shallow, located at the foot of a 50-meter vertical jump, making it a unique natural monument.
The area around Collbató, particularly the Montserrat massif, offers a variety of outdoor activities. You can find numerous mountain hikes, such as those detailed in the Mountain Hikes around Collbató guide, and general hiking trails, including those in the Hiking around Collbató guide. Road cycling routes are also popular, as shown in the Road Cycling Routes around Collbató guide.
The caves maintain a consistent cool temperature year-round, making them a good destination regardless of the season. However, visiting during spring or autumn might be more comfortable for combining your cave exploration with outdoor activities in the Montserrat Natural Park, as the weather outside is milder.
Yes, the Bauma dels Plecs del Llibre is a natural monument consisting of large blocks forming a spacious shelter. It's known as a good bivouac spot with a unique atmosphere, offering a 'duplex' with dining and sleeping areas, and views of the Plecs del Llibre. It's a popular base for climbers.
Visitors are captivated by the natural beauty and geological significance of the caves, appreciating the breathtaking natural art sculpted over millennia. The historical and cultural importance, including Neolithic remains and Gaudí's inspiration, also adds to the appeal. Many enjoy the guided tours that explain the geological processes and share local legends.
While the main tourist caves are accessible, some natural cavities like Cova de l'Arcada can be more challenging. Canyoning enthusiasts, for example, can access it from above through the Torrent de la Coma Alta, abseiling to the cave's entrance. The Cova del Cabrit is also a spacious balma well-known to climbers.
