Time Out says
Located in the northern suburb of Greensborough, the Kalparrin Gardens are a favourite with locals, as well as local ducks.
Within the gardens you’ll find barbecue facilities and picnic areas as well as tennis courts, BMX jumps, a skatepark and a bike trail.
The centerpiece of the gardens is Kalparrin Lake, with its picturesque footbridge. The water in the lake comes from storm water drains and is stored to be used on the surrounding grassland of the gardens and sporting facilities. While the water sits in the lake it is cleaned in part by the natural wetlands around it, harvesting close to 17 Olympics sized swimming pools of water a year. This process means that the irrigation and water supply of the gardens and nearby areas is fully sustainable.
The playground in the gardens is situated right on the lake with a fence separating the two, meaning children can jump, climb and explore the slides and swings safely.
