The southern end of the protected area has subsequently been changed into the Tsingy de Bemaraha National Park, covering 666 square kilometres (257 sq mi). The northern end of the protected area remains as a strict nature reserve (Réserve Naturelle Intégrale) covering 853 square kilometres (329 sq mi). It is characterised by needle-shaped limestone formations, above cliffs over the Manambolo river.  The incredibly sharp limestone formations can cut through equipment and flesh easily, which makes traversing them extremely difficult.
Tourists can access the national park by road from Morondava, a town 150 km south of the park. Limited access is also possible from the town of Antsalova, which can be reached by plane from Antananarivo or Mahajanga.
