Spectacular evidence that is found in this area of the Serral de Can Ros and that above it, we find the mountain of Puig Vicenç. It is worth seeing the curious shapes that the mountain offers.

Beautiful place with incredible views. Here are the caves of Can Riera, a hidden natural oasis in Torrelles de Llobregat. They are three clay caves with reddish and orange walls, shaped by the erosive action of wind and rain over thousands of years. On weekends there are usually a lot of people visiting the caves, so if you can, try to go during the week.

The Grott Mine is a tunnel of almost one and a half kilometers that is located in the Sierra de Collserola. Its construction was to carry water from the Pantano de Vallvidrera to the old municipality of Sarrià.

A strange cave in the side of the trail. It is a popular place for people to visit on a nice trail near Can Coll. I am not sure if the cave actually goes anywhere but the trail at the right time of the day gets beams of light that are magical.

According to Sergi Falguera, a collaborator of the Friends of the Geology Museum association, the site began to be exploited in the 17th century, but the most important extractions date back to the 19th and 20th centuries, when it was named Juanita. . It was part of the land of the Masia de Santa Caterina, in the neighborhood of Pedralbes. The mine still has several access tunnels. It is low in water, but it is not drinkable because it carries the acid that is formed from the oxide of minerals

While Sant Just Desvern itself has smaller, local formations, the broader Catalonia region offers several impressive cave systems. The Can Riera Caves are a local natural monument known for their reddish, clay walls. For a grander experience, consider the Salnitre Caves (also known as Montserrat Caves) near Collbató, famous for their extensive stalactite and stalagmite formations, or the Coves Meravelles in Benifallet, which boast unique 'eccentric' formations.
Yes, there are several options suitable for families. The Waterfall and Grotto in Parc de Torreblanca is a romantic garden featuring an imaginative design with caves, islands, lakes, and waterfalls, perfect for a leisurely family outing. Another great spot is The Cave Near Can Coll, a curious cave along a forest trail that has both an entrance and an exit, making it a popular and fun discovery for visitors.
The region around Sant Just Desvern features interesting historical underground sites. The Juanita Mine is an old mining site with several access tunnels, dating back to the 17th century with significant exploitation in the 19th and 20th centuries. Additionally, the Mina Grott is a nearly 1.5-kilometer tunnel in the Sierra de Collserola, originally built in the early 19th century to transport water and later used for an express train.
The caves in the wider Catalonia region offer diverse geological formations. The Salnitre Caves (Montserrat Caves) are renowned for their spectacular stalactites, stalagmites, columns, and whimsical rock formations, including an 'Elephant Room'. The Coves Meravelles in Benifallet are particularly famous for their 'eccentrics' – unusual and delicate cave formations. Locally, the Can Riera Caves are notable for their reddish and orange clay walls, shaped by natural erosion.
Yes, guided tours are available for some of the larger cave systems in Catalonia. The Salnitre Caves (Montserrat Caves) offer guided tours through their 400-meter underground passageway. Similarly, the Coves Meravelles in Benifallet provide guided tours lasting about 45 minutes, showcasing their impressive formations. For local sites like Juanita Mine or Can Riera Caves, exploration is typically self-guided, though access to Can Riera Caves is currently prohibited.
The area around Sant Just Desvern and the caves offers a variety of outdoor activities. You can find numerous hiking trails, such as those leading to the Cave Near Can Coll or exploring the Collserola Natural Park. For more options, check out the Hiking around Sant Just Desvern guide. There are also extensive MTB Trails around Sant Just Desvern and Running Trails around Sant Just Desvern for those looking for more active pursuits.
Most caves in the region maintain a constant temperature year-round, making them suitable for visits in any season. For example, the Salnitre Caves have a constant temperature of 14 degrees Celsius. However, if you plan to combine your cave visit with outdoor activities like hiking, spring and autumn offer the most pleasant weather conditions. Weekdays are generally less crowded than weekends for popular sites.
Given the constant cool temperatures inside many caves (around 14°C) and high humidity, it's advisable to wear layers, even on a warm day. Comfortable walking shoes with good grip are essential, as paths can be damp or uneven. For more adventurous cave explorations, such as those offered at L'Espluga de Francolí Caves, specialized gear like wetsuits and helmets may be required, which are typically provided by the tour operators.
Yes, the Cova del Toll in Moià is one of the most significant prehistoric caves in Europe. It preserves vestiges of human occupation from the Paleolithic period and remains of ancient fauna like cave bears. This cave offers a unique opportunity to connect with prehistory and learn about the earliest inhabitants of the region, making it an excellent educational experience.
While Sant Just Desvern itself is well-connected to Barcelona, reaching the major cave systems like Salnitre Caves (Montserrat Caves) or Cova del Toll often requires a combination of public transport (train or bus) and then a local connection or taxi. It's best to check specific routes and schedules for each cave, as direct public transport links might be limited. Local attractions like the Waterfall and Grotto in Parc de Torreblanca are more easily accessible within the immediate vicinity.
For a potentially less crowded experience, consider visiting during weekdays rather than weekends, especially for popular sites. While the Can Riera Caves can be busy on weekends, they offer a more secluded feel during the week, though access is currently prohibited. Exploring smaller, local grottoes or rock shelters found along hiking trails in the Collserola Natural Park might also provide a more tranquil experience compared to the larger, well-known tourist caves.
