Idyllic Medjumbe is a narrow sliver of island draped with white coral sand. There are no permanent residents. Instead Medjumbe hosts an airstrip, an old lighthouse and the paradisaical Anantara Medjumbe Island Resort. It's located approximately 70km due north of Ibo.
The much larger island of Matemo lies 20km north of Ibo and has been inhabited for generations – it was an important cloth-manufacturing centre into the 17th century. Today villages dot much of the north and interior of the island. There's no resort, but camping is available through Baobibo on Ibo, and Ibo's Miti Miwiri can help arrange day trips.
