Mountain gorillas are not the only endangered primates on the Virungas. The volcanoes are the last stronghold of the golden monkey which can be tracked through its bamboo habitat on the slopes of Mt. Gahinga. As with gorillas, contact time with this rare primate is limited to an hour. Visitors who sign up for the habituation experience, however, can spend all day following this striking orange-coated monkey in the company of researchers where gold meets silver.
