I live in the conservation belt along the Yarra River between Eltham and Warrandyte. Just 700 m due south from my house is the boundary of the the Warrandyte State Park. This section of the Park is notionally closed – but entry can be gained readily. Inside – the Park is lightly timbered, with the Yarra River below. There a gurgling sound, as the river is running through the minor rapids, called Laughing Waters.
