Lake Alexandra
Lake Alexandra is a postcard-perfect oasis in the middle of Southern Highlands suburbia. There is a playground for the kiddies, jogging path and exercise equipment for health enthusiasts, birds aplenty for bird watchers, picnic tables and BBQs for travellers on a quick break, a large shelter for ad hoc events on any occasion, and the whole park is only steps away from denser bush land where you can observe the local flora and fauna. As pretty a place as anybody could want, and it's all here in our own backyard.
