Greystoke Mahale. In the forest’s dappled sunlight, chimpanzees romp and commune around Greystoke Mahale. At the lakeshore, on a white beach, Greystoke opens its shaggy arms, hewn from vintage dhows, proffering yet another level of pleasure to all intrepid guests. This famous lodge by a gin-clear lake lives and breathes chimpanzees. It offers a large central dining area, a communal dining table, a library, and an open air bar for guests to make use of.
