Since the loss of the habituated Lossi gorillas to Ebola in 2002, the nearby Odzala National Park now presents one of the best options for seeing western lowland gorilla (WLGs). They are not yet habituated, but can be seen from hides as they visit bais (open clearings in the forest). The most famous bai is Mbeli Bai, in Nouabalé-Ndoki National Park, where about 100 gorillas have been monitored by the Wildlife Conservation Society for a decade; gorilla groups can be seen wading into the marsh to forage for water plants alongside forest elephants, buffalo and antelope such as sitatunga.
Rescued gorilla orphans (WLG) are being rehabilitated back into the forest in the Léfini Reserve (two hours’ drive north of Brazzaville), where visitors can view silverbacks on a forested island from a boat.
