Welcome to Parc National de Tsimanampetsotse
Amid the rampant spiny forest, watch also for a large banyan tree full of parrots and ring-tailed lemurs and whose tendrils fall several storeys into a flooded sinkhole. Verreaux's sifaka are commonly seen during daylight hours, and keep an eye out for sleeping nocturnal species such as the tiny grey-brown mouse lemur, fat-tailed dwarf lemur and white-footed sportive lemur.
The MNP office is in Efoetse, 3km from Ambola. You can arrange a mandatory guide and itinerary here, and a map of all the current routes is on display. There are several circuits, from 30 minutes to 3½ hours in length.
