Isalo National Park

When Is the Best Time 

The Isalo National Park is accessible throughout the year due to its dry tropical climate. However, the winter time from December to February experiences most of the annual precipitation. The tourist season starts in April, the peak season is during summer in July and August and the best months are September and October. At these months, the end of the dry season, there are only a few mosquitos around, and you may spot newborn baby lemurs.

Compared to other parks wildlife is not as numerous due to the higher temperature. However, Isalo is an outstanding park to spot the awesome Verreaux’s Sifakas along the streams in the canyons.

Another highlight is the elephant’s foot plant (Pachypodium rosulatum) which is in bloom from August to early October.

The most popular spot in Isalo is the "Piscine Naturelle" therefore it can get pretty busy especially during midday to escape the heat.

Pleasant day temps from April to September ranging between 23°C and 28°C / 74°F and 82°F though nights are chilly between 10°C to 15°C / 50°F - 59°F. The rest of the year temps are around 30°C / 86°F. Inside the canyons, it's cooler while hiking through the savanna without any shelter is pretty hot and strenuous.

Review and Tips 

The National Park was established in 1962 and covers an area of 815km²/81,500ha. Isalo is located at an altitude of 900m/2952ft to almost 1100m/3608ft. The plateau and the rocks are from the Jurassic area and build awe-inspiring scenery. You will find several hikes to waterfalls, canyons, the wild mountainous region, through some left forest patches, and along the plateau. Isalo offers incredible panoramic views of a colourful landscape mainly shaped by thousands of years of erosion from wind and rain. It's a sacred place for the Bara tribe. While hiking your guide will show you several caves in the walls which are burial sites.

You may spot the Verreaux's sifakas or ring-tailed lemurs very close. They are accustomed to humans. Isalo is also famous for local endemic plants like the elephant's foot. Flatid leaf bugs, stick insects, coloured caterpillars, and other unknown insects occur there as well. It is not easy to get an experienced and motivated guide, but you are not allowed to walk independently. The guided hikes are a bit pricey in comparison to other National Parks in Madagascar. The entrance fee for one day is Ar 25.000 (6,20 €) and Ar 37.000 for two days (9,20€).

However, if you come here, stay at least three nights and spend two full days in the park. The first day we hiked through the savanna and to the "Piscine Naturelle" and the next day to "Canyon des Makis" and "Canyon des Rats". Bring your bath clothes and take a refreshing dip in the pools.

How to Get There

The Isalo National Park is located 700km/435mi from Antananarivo which could be a 15-hour drive and from Tulear/Toliara at the west coast a 3-4 hours (230 km/ 143 mi) journey. Usually, you arrive from Andringita or Ranomafana (which is just 5.5 hours). The park is directly located at the R7. Although "taxi brousse" connecting Antananarivo and Toliara regularly we would advise hiring a driver with a car.
