In northern Madagascar, Ankarana National Park protects a limestone massif renowned for its Tsingy, sacred caves, and a network of underground rivers considered Africa's largest. Spanning roughly 18,220 hectares, it combines dry forests, crater lakes, and a karstic landscape dotted with cavities, home to lemurs, bats, and rare troglodytic fauna.

Why visit Ankarana

Ankarana ranks as Madagascar's second-best site for observing Tsingy after Bemaraha, yet offers something distinctive: a dense underground realm featuring eleven caves, some harboring royal burials and active ritual sites. The park combines several compelling reasons for a visit:

• Karstic landscapes sculpted by erosion, accessible via walkways and technical trails.
• Rich endemic fauna: 10 lemur species, 92 bird species, 13 documented bat species.
• Living cultural significance centered on sacred caves, where local communities still leave offerings.
• A singular underground ecosystem with underground rivers inhabited by creatures devoid of pigmentation and eyes.

What to see and do in the park

The Tsingy of Ankarana

Tsingy are limestone formations carved by rain and wind into narrow corridors, razor-sharp ridges, and mineral labyrinths. The Anilotra camp serves as the base for approaching them: expect roughly two hours of hiking to reach it, passing the Green Lake, a crater lake nestled in vegetation. Once there, wooden boardwalks allow you to overlook the fragile rock formations. A few pachypodiums manage to take root on the limestone, adding greenery to an otherwise mineral landscape. Some sections require rock scrambling or squeezing through tight crevasses, so reasonable fitness helps.

Sacred caves and the underground world

The park encompasses eleven caves formed by underground water circulation. Several still serve as royal tombs or sanctuaries, retaining ritual significance. Inside, you traverse chambers adorned with stalactites, stalagmites, helictites, helemites, and calcite draperies resembling cloth. The cool cavern air contrasts sharply with the heat outside, making exploration pleasant even midday.

Fauna and flora

The isolation of certain sinkholes has preserved diverse wildlife. Among lemurs, you'll spot notably the Hapalemur griseus, Eulemur fulvus, and the northern sportive lemur. Among 92 recorded bird species is the brown mesite, endemic to Madagascar. The park also harbors fossa and several chameleon species. Underground rivers host troglobic fauna lacking pigmentation and eyes, while caves shelter 13 bat species. Some rivers also contain crocodiles, occasionally large ones: caution near water is essential. Vegetation blends Canarium of Madagascar, pandanus, lianas, aerial orchids, and baobabs, observable along botanical trails.

When to visit Ankarana

The dry season, from April/May through October/November, remains the most favorable window. Tracks are passable, underground rivers less hazardous, and Tsingy trails more stable. During the rainy season (December to March), parts of the park become inaccessible due to rising waters and trail conditions. For lemur observation, early morning and late afternoon remain most active.

Practical information

• Duration: from half a day for a short loop to 2-3 days combining Tsingy, caves, and camping at Anilotra camp.
• Guide: a certified local guide is mandatory at park entry.
• Equipment: sturdy hiking boots, gloves for Tsingy (very sharp rock), headlamp for caves, ample water, light clothing, and sun protection.
• Fitness level: some itineraries require light scrambling and tight passages; others suit regular hikers.
• Rates: park entry fees and guide services payable on-site at moderate rates.

How to get there

The park sits in northern Madagascar, within the DIANA region, several hours south by road from Antsiranana (Diego-Suarez). Access is by 4x4 via RN6, with two main entrances: Mahamasina (most frequented, east side) and Matsaborimanga or Ambondromifehy for combined circuits. From Antsiranana, expect roughly half a day's drive. Visitors from Ankify or Nosy Be travel north up RN6. Most visitors arrange passage through a local operator, simplifying transfers and camp logistics.

Combine with your itinerary

Ankarana fits naturally into a northern circuit or broader Madagascar route. To extend your nature and culture experience, several sites complement your visit:

• Ranomafana National Park, another major protected area, focused on rainforest.
• Andringitra massif, for highlands and granite landscapes in the south.
• Lemurs' Park, near Antananarivo, useful for an introductory lemur experience.
• The Zafimaniry, to discover a UNESCO-listed cultural heritage.
