Wildlife

Isalo is not a prime wildlife-viewing destination. There are only three lemur species active in the day on record, but two of them are particularly charismatic: the ring-tailed lemur and the Verreaux's sifaka, known for its dance-like movement when running on the ground. The lemurs can mostly be found in the canyons, such as Maki Canyon and Rat Canyon.

Scenery

The park is a photographer’s dream. The evening light usually plays its magic over the sandstone formations eroded into amazing rockscapes, canyons and gorges. A popular scenic highlight is ‘la fenêtre de l’Isalo’ (the Isalo window). This is a natural window sculpted out of the rocks, letting through the setting sun while capturing the surrounding landscape with its balancing boulders and jagged peaks.

Weather & Climate

Isalo has a dry tropical climate. Annual rainfall figures are low, but there is a Wet season from November to April. The middle of this, December to February, is very hot and humid. The coolest months are June to August with an average daytime temperature of 26°C/79°F. During this period, nights are quite cold with the lowest average of 11°C/52°F being in July.

Best Time To Visit

Isalo can be visited throughout the year. Most people will however prefer the Dry season months, from May to October, when hiking conditions are perfect. The magnificent scenery of the park is enhanced by beautiful light. In the Dry season it is always sunny and bright, and most days start and finish with a photogenic sunrise and sunset.

4/5

The rugged terrain of Isalo National Park is formed by eroded sandstone formations jutting out of the surrounding grassland. The scenery, with its balancing rocks and jagged peaks is strangely reminiscent of the Wild West. There is a good...

Spent a full day walking through the park, including a visit to the Piscine Naturelle and through canyon. Very pleasant any enjoyable, though very hot and with not a lot of shade. With a good guide, as we had, we saw a good amount of...
