The Isalo National Park is well-known for its Jurassic scenery: sandstone formations riven by numerous gorges and canyons, fire-resistant forests, palm-lined oases, several natural pools and large grassland areas. The park’s highlight are 14 lemur species, some of them active during the day, and some nocturnal. One of them is an extremely cute grey mouse lemur, that sleeps in a tree hole to restore energy before the breeding season.
The dormancy time varies from one day to a few months between April and October. Canyon des Singes and Canyon des Rats lead to the tranquil refreshing turquoise natural pools which are the favourite places of Benson’s Rock Thrush, an amiable blue-orange plumed bird. A beautiful Malagasy rainbow frog has an unusual colouring that is different at day and night. Among 340 plant species, the most noted are elephant’s foot plant, growing in the sunny and stony areas. One may be exploring rich nature of Isalo for days and weeks. The best time to visit the site is October since most lemurs give birth by the end of the month and this is also the breeding season for most birds.
