The MNP office is located 60km from Sambava, and 40km from Andapa, in the village of Manantenina, and arranges entry permits (per day Ar45,000). Guide/cook fees are Ar25,000/15,000 per day if you provide the guide’s food, Ar30,000/20,000 otherwise. Porters are Ar4000 to Ar7000 per day depending on the length of the hike. An excellent English-speaking guide is Mosesy, the head of the local guide organisation. To maximize your chance of seeing a silky sifaka, an additional specialist guide is necessary.
