Yanchep National Park
Sure, it’s nice to cuddle a koala in an enclosure, but it’s far more exciting to see them in the wild, which you can do at this park, located 45 minutes north of Perth. Take the 787-foot Koala Board Walk through native bush with your eyes raised skyward to see one of the state’s largest populations of koalas. Watch for western gray kangaroos on the 2-km (1.2-mile) wetland walking trail around Loch McNess lake and then escape summer’s heat by joining one of several daily underground tours of Crystal Cave, where cooling caverns open up to impressive stalactite galleries and clear water pools. The park is also a lovely picnic spot, and there's a hotel and café within the grounds.
