Parc National Mananara Nord is something of a misnomer: not only is the park located south of Mananara, its entrance is in Sahasoa, 30km from Mananara. It encompasses some of the last remaining lowland rainforest in the country. An additional 10 sq km of islets and surrounding reefs are protected as a marine park, the largest being Nosy Atafana. The park itself isn't the most traveller-friendly: the two-hour terrestrial circuit requires four hours of hiking to get there.
