There is a network of tracks in the area ideal for trekking. Many follow the ria around the coast. Other tracks can be quite difficult; you must be fit. Tufi Dive Resort can arrange a guide and village stays, or you could take your chances and ask around yourself. The villages and the resort can arrange boats to pick you up at various locations at the end of your walk.
Orchids, birds and butterflies can also been seen in the surrounding jungles and again, Tufi Dive Resort can arrange guides to view these.
