The gorges of central Kimberley are known for their fossils and for their large colonies of bats, including Windjana, Tunnel Creek, and Geikie Gorges. Lake Argyle and other wetlands of the Ord and the Kimberley are important habitats while there are important populations of shorebirds in the Ord estuary, Eighty-mile Beach and Roebuck Bay, which has been described as "one of the most important stop-over areas for shorebirds in Australia and globally". Finally there are a number of rocky islands off the north coast that are home to seabirds and turtles.
