The Cau dels Emboscats is one of the cavities that served as a refuge during the civil war. Specifically, several people hid from Sant Llorenç Savall. The situation of the cave was kept secret for many years after the end of the conflict. It wasn't until October 28, 1956, that Biel Dalmau, from the Mas de les Oliveres, explained its location and history to Josep Maria Torras Homet. The mouth is very irregular. It opens in the form of a chasm that falls on an inclined floor. Then there is a 2 meter ledge leading to the main gallery parallel to the cliff and about 20 meters long. In the middle of the gallery there is a large window that forms a kind of side room poured into the steeply sloping cliff. The cavity ends in an elbow and a small room, where small stalactite formations and parietal crusts can be observed.

An incredible road with almost no cars. On one side you have cliffs and on the other stunning views. At the end of the road you will come to a monastery. Pay attention in the curves because, despite the fact that there are not many cars, when one passes there is not much space left on the road.

Old Benedictine sanctuary located in the municipality of San Feliu de Codinas, in the Catalan region of Vallés Oriental. The church was built in a cave, with its own stone serving as a roof. It is the largest troglodyte church in the country. It has a Romanesque portal formed by a semi-circular arch.

Small bauma located on the right bank of the PR-33 that leads from Figaró to Montmany, inside the Sot del Bac. Bauma formed by the lateral excavation of the Sot del Bac stream, 35-40 meters above the current talveg. It is a not very deep cavity excavated in a rocky margin or slope where the light penetrates. This has graffiti and evidence of occupation inside, with traces of having been set on fire. It is a suitable place for shelter or bivouac. At least before it was very common to use it. The Sot del Bac pass would be a natural path used by the first human communities, both to stock up on various natural resources (water, hunting and gathering) and as a place of passage and communication between the Gorge sector and Puiggraciós and the Cingles de Bertí. Currently this is occupied sporadically by walkers and climbers.
