The National Park of Mananara Nord lies in the Antongil bay at 250 km north of Toamasina and comprises a 240 km² of terrestrial area and a marine park of about 1000 km². Although it was established in 1989, the number of the visitors is still very low as a good experience of the area is needed to organize a visit of the park. Indeed, few agencies or Tour Operators recommend this destination.

The vegetation is formed by tropical humid forest, mangroves and swamps. The marine section is formed by several small islands and coral reefs. Nosy atafana is very nice place for snorkeling and diving. Divers can find over 180 fish species and more than 100 molluscs and echinoderms. Humpback whales are also easy to see between July and September.

Mananara Nord gives shelter to a remarkable variety of fauna. This is the best place to see the Aye-Aye, so far. Concerning the mammals, there are 17 rodents and 13 lemur species such the eastern woolly lemur, brown mouse lemur and the biggest of all lemurs, the indri-indri. The indri of this park is almost completely black and darker than the species of Andasibe National Park. Around 77 birds like Red-tailed Vanga, helmet Vanga and Madagascar kestrel, 21 reptiles and 8 amphibians are cataloged in the terrestrial part. The flora is very rich since 1200 different plants have been recorded. More than 40 species of palm trees and tropical flowers including some local endemic orchids decorate this magnificent forest.

The Betsimisaraka and the Tsimihety are the main ethnic groups of this region. They are farmers growing rice, coffee, vanilla and cloves. They are very welcoming and friendly.

The climate is humid with frequent rains and warm temperatures all over the year. The Park is accessible all the year round by road or by boat. It lies next to the terrible coastal road between Soanierana Ivongo and Mananara Nord

At present time, Mananara Nord is not deserved by domestic flight. It is though possible to reach the park by boat or by 4WD.
