In an ongoing series, Koala Hospital, National Geographic travels to Port Macquarie, Australia, a few hours from Sydney, to visit the 40-year-old refuge for wild koalas. Volunteers there are clearly delighted at the chance to frolic with the fluffy marsupials, who cling adorably to tree branches and human legs alike. If you can't make the trek but you want to contribute, you can adopt a wild koala via the hospital's website, or help them plant a food tree, to counteract the koalas' loss of habitat.
