A spectacular and biodiverse reserve with an altitude range of 500 to 2,658 metres and mountainous outcrops of ancient Precambrian granite, waterfalls, lakes and unusual vegetation. Pic Boby, Madagascar’s second highest mountain, is a tough climb but there are other less challenging trails through some magnificent scenery and habitats, including lowland forest, high humid tropical forest, sclerophyll and bamboo forest, bush and heathland.
It has much endemic flora and over 100 species of birds, as well as over 50 mammal species including mountain-adapted ring tailed lemurs with thick coats. The climate ranges from humid tropical in the lowland rainforests to below freezing at altitude – indeed, it is the only place in Madagascar where snow has been recorded.
