Isalo National Park is not primarily a wildlife destination: most people come here for the spectacular scenery and hiking opportunities. Even so, Isalo does have seven lemur species. Three can be seen by day in the wooded canyons and at Namaza Campsite, and four are active at night. Chameleons, lizards and colorful frogs are some of the smaller animals to look out for.
Wildlife Highlights
Maki Canyon (Canyon des Singes) or around Namaza Campsite is best for ring-tailed lemurs and the dancing Verreaux’s sifaka. In the absence of night walks, it can be difficult to see the park’s nocturnal species: grey mouse lemur, greater mouse lemur, red-tailed sportive lemur and Coquerel's giant mouse lemur. You’ll need to watch instead around the campsites at night. The Piscine Naturelle is good for endemic frogs, such as the painted burrowing frog.
Best Time for Wildlife Viewing
Isalo is mainly a scenic hiking destination and conditions for that are best during the Dry season (April to October). Lemurs are active and can be spotted throughout the year, but October is a good time to visit as many lemurs have babies then. During the warmer months of the Wet season (November to March), reptiles are easier to see as they are more active and display brighter colors.
