This place was undoubtedly the "highlight" of this stage! Already arriving in the valley, you get the impression of entering another world, literally: the Grigne mountains loom, almost vertical, closing off the valley, the steep road descending towards the stream becomes a small path, the vegetation becomes dense... almost a jungle. finally, you arrive at this spectacular cave, a natural bridge, a very cool place where it is mandatory to stop... also because, immediately after, you climb a very steep staircase!

Beautiful pools with crystal clear water. Trail 15b (Lake Trail) repeatedly crosses the stream, often with fixed chains; waterproof boots are highly recommended, especially in the less warm months.

The Mother of God depicted and venerated here is the one from Lourdes. This well-known Marian pilgrimage site is located in the French Pyrenees and is visited by many people every year, including many sick people who hope for healing. The devotional image of the Mother of God has become widespread - not only in France - and believers have built Lourdes chapels and grottos everywhere. The church's memorial day for "Our Lady of Lourdes" is on February 11th, the anniversary of the apparition of the Virgin Mary (1858), when the Mother of God appeared to 14-year-old Bernadette Soubirous in a rock grotto very close to Lourdes. Bernadette later became a nun and died at the age of just 35. On December 8th (the Feast of the Immaculate Conception of Mary) 1933, she was canonized by Pope Pius XI. The commemoration of the Madonna of Lourdes is also World Day of the Sick.
