These are all from an August 2023 visit to Mahale Mountains National Park, on the shore of Lake Tanganyika. It takes trekking up in the mountains to find the chimps, but the scouts usually find them before we start the trek, that way we know where to go. They are used to humans being around, and know we are not a threat, so they are comfortable enough to be very close to us. It is quite a thrill to see wild chimps for the first time!
