The Isalo National Park is part of the Ranohira municipality in the Ihorombe region. The park is located 279 kilometres south of Fianarantsoa and 80 kilometres south of Ihosy. The park is the most visited protected area in Madagascar and a popular highlight when discovering the Great South.

Isalo National Park was founded in 1962 and is administrated by Madagascar National Parks since 1997. The park is situated along the RN7, a tarred road connecting the capital of Antananarivo with Tulear. The road is in very good condition and accessible all year round. The route from Antananarivo to Ranohira, also known as the door to Isalo, takes about 15 hours by car (701km). From Tulear to Ranohira is a 4-hour drive (250km). It is also possible to travel by taxi-brousse, which leave daily from Fasan’ny Karana station in Antananarivo, Antsimo station in Fianarantsoa and Sanfily station in Tulear.

The park spreads over an area of 81,540 hectares, with an average length of 59 kilometres and an average width of 22 kilometres. The perimeter of the park is 164 kilometres. The altitude varies between 514 metres and 1,268 metres and some of the canyons are up to 200 metres deep.

The Isalo massif is a continental sandstone plateau, dating back to the Jurassic times. The park features various sandy valleys and narrow canyons. Strongly attacked by erosion, the rocks vary in shape and composition. The soil in the park is rich in iron and aluminium.

In the eastern part of the park, the following rivers flow from north to south: Marandra, Tsiombivoly, Andriamanero, Andranonkova and Namaza Ianakandrarezo, all small tributary rivers of the Menamaty, a tributary river of Mangoky. In the western part, the following rivers stream from north to south: Sambay, Amboloando, Ankademoky, Sakamalio, Hoanga, Vohibasia, Andranomena and Sambalahitsara Analakira, all of which are small tributary rivers of Malio, another tributary of the river Mangoky.

The climate is tropical dry, with an annual rainfall of 800-1000mm in the months of December to March and an average temperature of 17°C in June and 25°C in February.

Since centuries the Bara people dominate the Isalo region. Their main activities are livestock, especially zebu, and agriculture.

Landscape

This huge eroded massif extends over a large grass bed, dotted with forest. Isalo offers a fantastic, colourful landscape, shaped by erosion, and incredible panoramas.

The south consists of a large, sandy plateau, 800 metres above sea level. The plateau is characterised by savanna, shrubs, prairie grass and naturally eroded sandstone hills.

The east consists of a large plateau with an altitude of 1000 to 2000 metres. It is largely covered by sclerophyllous plants and prairie grass. The plateau is cut by numerous varyingly deep canyons with more or less permanent streams. The east of this plateau is dominated by rocky cliffs, characteristic for Isalo.

The west is a vast monocline plateau with an average altitude of 1000 metres. It is almost entirely covered by sclerophyllous plants and large plains of prairie grass. In several places the plateau is cut by canyons, similar to those in the east. Like the east plateau, also the west plateau ends by rocky cliffs.

The central part between the east and the west is dominated by a valley, a sequence of plains and low-lying plateau, surrounded by sclerophyllous plants and grass meadows.

The north consists of a large rock barrier in the eastern part with typical rocky escarpment at its end, varying in altitude between 800 and 1200 metres. The centre is formed by a vast monocline plateau, about 600 to 700 metres above sea level, which greatly reduces the lowering to the Amboloando river. The eastern part is a low plateau of 600 to 700 metres above sea level, descanting to the Malio river.

The area surrounding the park in the west, east and south consists of peneplain with an average altitude of 800 metres. (A peneplain represents the final stage of fluvial erosion in times of extended tetonic stability.) In the west remains some forest along the river beds of Malio, Analalava and Analambia, forming the park boundary at this side. In the east, there is also a remnant forest along the river bed of the Menamaty, but smaller in size compared to the west. The rest is dominated by a large tree and shrub savanna which occupies a large area with prairie grass.

Guides and entrance fees

The park office is located in Ranohira, 3 kilometres east of the park. There you can inform yourself about the various tours, guides and their rates as well as possible accommodation costs. Please bare in mind that the office does not open before 7am, so it is advised to obtain an entrance permit already a day in advance in order to have a full day in the park.

There are 70 guides working in the park. All speak French, as well as some English, Italian and German. All guides are educated in general culture, ecology, geology, local culture and technical guidance. A noticeboard informs about the specialty of each guide.

More information about the park is available in the Maison de l'Isalo, an interpretation centre located in Zahavola, about 9 kilometres south of Ranohira along the RN7 direction Tulear. The centre holds a permanent exhibition about the geology, fauna, flora and the influence by the local people. The museum is open daily from 6.30am to 6pm, there is no entrance fee.

The admission fee for visiting the park depends on how many days will be spent in the park. Foreign tourists pay 25,000 Ariary for 1 day, 37,000 Ariary for 2 days, 40,000 Ariary for 3 days and 50,000 Ariary for 4 to 10 days (prices 2010). Guides are obligatory. The fee for a guide depends on the chosen tour (circuit) and can reach from 16,000 Ariary for the Natural Swimming Pool circuit to the 20,000 for the Maki Canyon. Porters cost 10,000 Ariary a day.

Circuits (Tours)

There are several circuits crossing the Isalo National Park. Visitors can choose between easy and medium level circuits. It is possible to combine individual circuits by staying overnight at a campsite in the park.

Piscine Naturelle - Natural Swimming Pool Circuit

This is the most popular circuit in the park. The trek leads you to a palm-fringed pool, constantly fed by a warm waterfall. You walk through diverse ecosystems from the cliffs to the Tapia plain, passing Bara and Sakalava graves.
