This Saturday (2nd of May) there is an extra good reason to visit. The good folks at the museum are conducting tram trips into the Royal National Park to the National Park Station. There you will be met by a Ranger who will escort you on a guided 1km walk to the Bungoona lookout.
The tram trip will cost just $6 per adult ($4 concession) and the guided walk is free and rated as easy. There is no need to book. Admission to the museum costs $15 and includes the tram ride.
