Which Madagascar national park features sharp limestone pinnacles known as 'tsingy'?

The Madagascar national park famous for sharp limestone pinnacles known as “tsingy” is Tsingy de Bemaraha.

Located in western Madagascar’s Melaky Region, Tsingy de Bemaraha protects a spectacular karst landscape formed as limestone was uplifted, fractured and eroded over immense spans of time. Rainwater dissolved the rock along cracks and joints, leaving dense forests of narrow blades, needles and ridges. The formations can be sharp enough to cut clothing and skin, making parts of the terrain nearly impassable without bridges, ladders or carefully designed trails.

The Malagasy word “tsingy” is commonly associated with the idea of walking on tiptoe, a reference to the difficulty of crossing the jagged stone. The protected landscape is also biologically important: caves, canyons, dry forests and waterways shelter lemurs, birds and other species found only in Madagascar.

The original protected area was established as a strict nature reserve in 1927. Its southern portion became Tsingy de Bemaraha National Park in 1997, while the northern section retained strict-reserve status. UNESCO recognized the wider natural area as a World Heritage Site in 1990. Isalo and Ranomafana are famous parks too, but neither is defined by this distinctive tsingy karst.
