The geological particularities of the land and the volcanic activity gave very curious natural sites that you have to see, so don’t wait more, put you hiking shoes and hurry up…
The Chaudefour Valley, one of the three valleys of glacier of the Massif du Sancy, is famous for its alpine flora and its spectacular sharped dykes: Rancune Tooth, Coq and Moine Crests. A site listed as National Nature Reserve since 1991, Chaudefour shelters beautiful landscapes, a rich fauna and wonderful geology sites.
The Rancune Tooth is a very famous place for climbing. Be careful, it is one of the hardest in France! Only experimented are allowed! Otherwise, right side, the Coq Crest is accessible from a very low level.
The Cotteuges Fairies chimney is a column with strange forms, and also calls the “curly lady”. During volcanic eruptions, a lava mass was projected in the air and fell back on a clay soil. Erosion erased the clay except under the gigantic basalt rock. This rock is now perched.
A peat bog is a humid area, colonized by vegetation, which the particular ecological conditions are made with stagnant water soil depriving oxygen the micro-organisms (bacteria and mushrooms) responsible of decomposition and recycling of organic material.
Pavin lake is the deepest lake of Auvergne and one of the most mysterious…With almost 7000 years it is still the youngest French lake of crater. Located around trees, it a very mysterious lake: its 800 meters deep circle is almost perfect, a depth of 93 meters that gave the lake dark looking water, however its water turns into a turquoise blue color around the edges….
The salted marshes of Saint-Nectaire
Natural curiosity linked with salted springs, a maritime biotope was formed in Saint-Nectaire. Around the marshes, various vegetal species live and they are called “halophile” plants, usually they liver around the seashore.
The Haute Dordogne valley
Birthplace of Dordogne River, the Haute Dordogne Valley is oriented North/South and go down Le Mont-Dore formatting a huge amphitheater because of erosion and then, go to La Bourboule thanks to a fault corridor.
