Pidia Village in Arawa. Get intouch with Zhon Bosco of Boug Tours and he will link you up with Carmelita, a local lady there. Most of the island is Matrilineal so almost every village you visit you will be see the system. But its not all that you may thing. Ownership of land and children passes from women to women, not the men. However, men make important decisions and women take on a more spiritual and cultural significant role.This is Zhons email info@bougtours.com.
