Centella Cave

Centella Cave is a limestone cave located within Ankarana National Park in northern Madagascar. It forms part of the extensive karst system of the Ankarana Massif, a Jurassic limestone plateau characterized by sharp limestone pinnacles known as tsingy, underground rivers, sinkholes, and complex cave networks.

The cave is one of numerous subterranean features within the Ankarana karst, which has been mapped and studied for its geomorphology and biodiversity.

Geography and geology

Centella Cave is situated within the Ankarana limestone massif, which dates to the Middle Jurassic period. The massif developed through tectonic uplift followed by prolonged chemical weathering and erosion, producing a mature tropical karst landscape.

The cave system exhibits typical speleothems such as stalactites and stalagmites, along with vertical shafts and subterranean waterways. Underground rivers Contribute to ongoing speleogenesis and groundwater circulation within the massif.

Ecology

The caves of Ankarana, including Centella Cave, support specialized fauna adapted to subterranean environments. Documented cave-associated species in the massif include several bat taxa and the blind cave-dwelling fish Glossogobius ankaranensis.

The broader Ankarana region is recognized for high levels of endemism and ecological sensitivity.

Tourism

Centella Cave is accessible through guided excursions organized within Ankarana National Park. The park is managed by Madagascar National Parks and promotes regulated ecotourism to protect fragile karst ecosystems. The dry season (May–October) is generally considered the most suitable period for cave visits due to improved accessibility.
