Located to the south of Leuchey, the Dhuis valley cuts deeply into the edge of the Langres Plateau, making it one of its major natural sites. It is bordered by steep cliffs with a variety of forest types depending on the direction of the slope: maple grove, dental beech grove, xerophytic beech grove, oak-erabaceous grove at the bottom of the valley, etc. A number of relict grasslands still exist, and vegetation that is particularly well adapted to drought has developed on the hard limestone slopes. There is also a very old revered oak (around 5 metres in circumference) near a major spring. The fauna is remarkably rich, including two bats: the Greater and Lesser Rhinolophus, protected in France since 1981 and in Europe under the Bern Convention and the Habitats Directive. The entomofauna, and more particularly the dragonflies, includes two rarities: the Agrion de Mercure, protected in France since 1993 and in Europe (Bern Convention, Habitat Directive), listed as a species in danger of extinction on the red list of animal species in France, and the Cordulégastre annelé listed on the red list of Odonates in Champagne-Ardenne. The site is in a good state of conservation.
