The Ankarana National Park is located in the Diana region in the northern part of Madagascar. The park lies 108 kilometres south of Antsiranana (Diego Suarez) and about 20 kilometres north of Ambilobe. The four rural disctricts of Marivorahona, Anivorano, Ambondrona and Antsaravibe surround the park. From Antsiranana it takes between two and three hours by taxi-brousse to reach the main entrance on the east-side at Mahamasina along the RN6. Most of the people living in the region belong to the Antakarana ethnic group.

Ankarana National Park has a total area of 18,225ha and an altitude of 206m. The predominant climate is dry tropical with an annual rainfall below 2,000mm. Most of the rain falls in January. The dry season lasts from April to November. March is the hottest month with a maximum temperature of 36.2°C and June is the coldest with a minimum temperature of 13.5°C.

The topography of Ankarana is characterised by limestone emerging from a basaltic plain 50m above sea level, forming the tsingy (sharp limestone karst pinnacles). Numerous underground caves and canyons traverse the massif. Four major rivers flow through the reserve: Besaboba eastward, Ankarana from the north, Antenan'Ankarana and Mananjeba from the south. The first three are underground rivers whose specific watercourses still remain unknown.


Fauna

For visitors of the reserve there is much to discover in the forest, rivers and caves. In 2010 a biological inventory identified:

  • 50 shellfish species and a large number of tsingy snails
  • 14 bat species, half the species of bats in Madagascar
  • 60 species of reptiles and amphibians
  • 11 species of lemurs
  • 96 bird species

Invertebrates

Ankarana is home to at least 50 shellfish species, including 10 water species. Amongst the most interesting species is the great land snail Tropidophora. Several species of collembola (springtail) and amphipods are endemic to the caves and streams of Ankarana.

Vertebrates

Fishes

The species Glossogobius ankaranensis is endemic to Ankarana. Glossogobius callidus (River goby) and Pachypanchax sp are also present in the streams of Ankarana.

Reptiles / Amphibians

Ankarana has a very high diversity of reptiles and amphibians, at least 60 species have been inventoried. Following species are endemic to Ankarana:

  • Frogs
    • Anodonthyla sp nov
    • Mantidactylus sp nov
  • Skink
    • Amphiglossus sp nov
  • Snakes
    • Alluaudina moquardi
    • Liophidium therezieni
    • Liophidium sp nov
    • Heteroliodon sp nov
    • Stenophis sp nov 1
    • Stenophis sp nov 2
  • Lizard
    • Lygodactylus expectatus
  • Gecko
  • Crocodile

Birds

There are at least 96 bird species in Ankarana, many of which are of great importance for conservation. They are:

Mammals

Ankarana is home to many species of mammals, including 14 species of bats, meaning that half of the bats of Madagascar live in the underground caves of Ankarana. Two amongst them are the smallest and biggest bats of the world: The Megachiroptere (Megabat) and the Microchiroptere (Microbat).

Of the 11 lemur species present in Ankarana, the most commonly observed are:

The famous Propithecus diadema perrieri, known as Black sifaka / Diademed sifaka, was last seen by park rangers in 1995 and 1996. Meanwhile, the presence of Microcebus myoxinus (Peters's mouse lemur) still needs to be to reconfirmed.

Endemic carnivores living in Ankarana are:

Guides and entrance fees

There are 50 guides working at the park, all with excellent knowledge about the park, its biodiversity and ecosystems, ethical guidance, culture of the Antakarana people as well as first aid.

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). The fee for a guide depends on the chosen tour (circuit).

Circuits (tours) in the eastern part of the park

Eight circuits cross the eastern part of the Ankarana National Park. The starting point for all circuits is the main office at Mahamasina. It is possible to combine several circuits at one visit.

The Cave of the Bats

Easy 2 to 3 hours trek, including a steep slope, to an underground cave with 8 species of bats from small to large size. It is possible to see some lemurs such as the Crowned lemur, Sanford's lemur and Northern sportive lemur. If lucky, one can see a Ring-tailed mongoose and even a Fossa.

Lost Rivers

Easy 1 to 2 hours trek, suitable for combining one-way with other circuits. Great views over the Ankarana landscape from the Ampasambazaha viewpoint. The track crosses a baobab forest, very close to the Ampondrabe river. The circuit ends at a big gulf (lost rivers) where the three Ankarana rivers flow away (especially spectacular after lots of rain). Along the track it is possible to observe animals such as Brookesia (Leaf chameleon), Crowned lemur, Sanford's lemur and Northern sportive lemur as well as birds such as the rare Dronge and Magpie-robin.

Tsingy Meva

Easy 2 to 3 hours trek with a steep climb and steep descent. The track passes through the northern Ankarana massif and the southern part of the Montagne d’Ambre. Along the track it is possible to see the entrance of the bats grotto. Trekkers have the opportunity to touch the tsingy and observe its particular vegetation, such as the endemic Pachypodium decaryi, Cyphostemma and Euphorbia ankaranensis. Lemurs include the Crowned lemur, Sanford's lemur and Northern sportive lemur. Furthermore, one can see the Ring-tailed mongoose, skinks (in the rainy season), Velvet gecko, Leaf chameleon and Flat-tailed gecko.

The Turrets of the Tsingy

3 to 4 hours walk, suitable for combining one-way with other circuits. The trek is easy, but the crossing of a small river is required in the rainy season. The track leads through the tsingy in the shape of turrets. A walk through crevasses gives the possibility to learn more about the typical vegetation of the tsingy. A large baobab tree with over 8m in perimeter is an ideal location for a break. Throughout the track one can see the Northern sportive lemur, the rare bird Crested coua and reptiles such as skinks (in the rainy season) and the Leaf chameleon.

Tsingy Rary

3 to 4 hours walk, suitable for combining one way with other circuits. The trek is easy, but the crossing of a small river is required in the rainy season. This circuit shows the picturesque landscape of the tsingy, the duality between limestone and volcanic rocks and the particular vegetation that grows there. Crowned lemur, Sanford's lemur, Northern sportive lemur, Madagascan crested ibis, White-breasted mesite and skinks (in the rainy season) can be seen.

The big Tsingy of Benavony

7 hours trek, moderately difficult because the track is mostly walking on the tsingy. This circuit is ideal to enjoy the wonderful landscape of the tsingy and its particular vegetation. The Benavony underground cave (250 metres) has very beautiful dripstones (concretions). Trekkers can see the landscape from a height from suspension bridges, which join two small canyons. Animals living in the area include the Crowned lemur, Sanford's lemur, Northern sportive lemur, Ring-tailed mongoose and fossa. The vegetation of the canyon is dominated by Moraceae (Ficus.

The Viewpoint of Ambohimalaza

4 to 5 hours trek, easy but steep in the final stretch. The track leads through a forest of the endemic tree "Taim-papango" and through the forest of big lianas and ficus. At the viewpoint a postcard picture surprises the trekker with views of Ambilobe in the west, over the tsingy and the Mozambique Channel spotted with islets (Nosy-Be, Mitsio etc.) at the horizon. From the highest point of the plateau one can see the whole northern part of the Ankarana National Park, which is dominated by the silhouette of Montagne d'Ambre. Along the track one can see Crowned lemur, Sanford's lemur, Northern sportive lemur, Spear-tailed gecko and birds such as Madagascar harrier-hawk, Peregrine falcon and Guinea fowl.

Lac Vert / The Green Lake

8 to 9 hours trek, moderately difficult because of the length of the track. This part of Ankarana is only accessible during the dry season from June to December. This track comprises the extent of the tsingy. The Amposatelo stream is ideal for a cool-down and swim. Trekkers can observe Crowned lemur, Sanford's lemur, Northern sportive lemur, Ring-tailed mongoose, fossa, birds such as White-breasted mesite, Madagascar crested ibis and flycatcher.
