Yanchep National Park is north of Perth, in Western Australia. Its bushland and wetland are home to western gray kangaroos and rich birdlife. Trails include a raised boardwalk among trees inhabited by koalas. One of many caves in the park, Crystal Cave is an underground limestone cavern with stalactites and stalagmites. Talks at nearby Wangi Mia Meeting Place illuminate the culture of the indigenous Nyoongar people.
