In the Park, grassy prairies extend everywhere, curving around peaks that look like ruins, filling every space available. Pandanus palm trees, solitary or in small clumps, endemic to the area, stand out on these plains like the last warriors of a defeated army. Straight trunks separate their thick leaves shaped like blades. A delicate plant – Salotsy – reputedly gave its name to the prairie which can only be visited accompanied by guides. There are five hiking trails. Only the “Grotte des Portuguais” trail, the longest one of the five major trails, requires several days camping. The easiest one is a mere walk of one to two hours over a rocky plateau ending at a pool of clear water at the bottom of a small cascade. This interesting walk allows the discovery of several of Isalo’s peculiarities. On the plateau, alongside the trail, are several mounds of “wishes”, as each mound corresponds to a wish called the “Tatao”. In the distance you can see several square tomb mounds, erected by the Sakalava, the predecessors of the Bara who occupied the area at the beginning of the 19th century.
