We went here as part of a cruise ship excursion on the same trip as the Alexander Graham Bell National Site. It is well worth the trip from Sydney. There is an big, old bridge that you can get some good photos of, and there are plenty of swimming opportunities in this huge saltwater lake.
Things change. The building now houses a gift shop but the area offers up some wonderfully scenic views of the lakes. Take a stroll along the waterfront and enjoy the fishing boats bobbing on the lake..
