Renowned primatologist Dr Jane Goodall has teamed up with G Adventures to offer a new range of wildlife trips. All are bound by a strict animal welfare policy while offering a chance to explore the habitats of some our closest genetic relatives. ‘Experience Borneo’ includes a river safari in search of native species like proboscis monkeys, grey gibbons (below) and orangutans (from £1,699pp for eight days; gadventures.com).
