Fodor's Expert Review 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, just above your head. 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 grey 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.

Yanchep National Park is a 45-minute drive north of Perth and is open every day of the year; book tours and get walk trail information at McNess House Visitor Centre.
