The Mount Nimba massif, located in the Guinean ridge that extends Fouta-Djalon, marks the borders between Liberia, Guinea and Côte d'Ivoire, more precisely in the eighteen mountains in the department of Danané. The highest peaks are located in Guinea and only Mount Richars-Mollard, which peaks at 1,752 m, forms a pivot at the border of Côte d'Ivoire.

The first explorations of the Guinean and Ivorian mountains date from 1909 and continued until 1959. The results of these exploratory missions led to the classification of this massif in 1944, with the status of an Integral Reserve.

Comprising an area of 5,092 ha for the Ivorian part, the Mount Nimba Integral Reserve has been a World Heritage Site since 1981 for the Guinean part and 1982 for the Ivory Coast. It has several advantages: the presence of rare endemic species (viviparous toads) and semi-aquatic insects; an exceptional floristic wealth (forests, savannas and high-altitude vegetation); a real water tower giving birth to more than 50 watercourses.
