This ancient path, near the hamlet of La Bletterie, is lined with majestic trees over 400 years old, whose distinctive shape is the result of human pruning. You'll feel like you're in a fairy tale as you admire the moss-covered trunks, the branches reaching toward the sky, and the lovers' initials engraved on the bark.

Saint-Vincent Rock is an imposing volcanic rock that offers breathtaking views of the surrounding forests and valleys. It is a natural wonder that dates back millions of years, when lava erupted from a fissure. Later, the sea receded, and tectonic movement lifted the lava, creating the impressive rock that stands today. You can explore the ruins of an ancient castle that once crowned the rock and admire a statue of the Virgin and Child, called "Our Lady of Up There," installed in 2012.

The Puy de Montoncel is an extinct volcano, culminating at an altitude of 1,287 meters. In a notebook, I wrote about it: "Its slopes are covered with a majestic thorn forest, with an archaic, sometimes primal beauty. The rare paths that cut through the woods wind along the slopes, in the shade of the green giants. These paths are the veins of the forest. They are tunnels of abundant oxygen. From meadows to groves, I feel as if I'm floating on an ocean of nature. At the summit of the puy, I find a plateau devoid of trees as if blown by the wind, and topped with a thick thatch. A huge iron cross rises into the sky, looking mischievously at the wind turbines on the neighboring ridges, which come to life with the sound of the air." I sit down on a wide carpet of green grass, a veritable velvet to rest my body after this first, sweaty climb. I light a pipe and cheerfully observe the Auvergne volcanoes that swell the horizon. Their supple, rounded shapes give the impression of observing distant hills. Puy-de-Dôme, Monts Dore, Puy-de-Sancy, I amuse myself by guessing the roofs I was clambering over the previous year.

The Rocher Saint-Vincent is an imposing volcanic rock that offers breathtaking views of the surrounding forests and valleys. The Rocher Saint-Vincent is a natural curiosity that dates back millions of years, when lava gushed out of a crack and formed a green horn. Later, the sea receded and a tectonic movement lifted the horn, creating the impressive rock that stands today. You can explore the ruins of an ancient castle that crowned the rock, and admire a statue of the Virgin and Child, called "Notre-Dame de là-haut", which was installed in 2012.
