Personally, I have enjoyed going to Bulleen Park on numerous occasions for family picnics, walks etc. Here is a little bit of information regarding Bulleen Park from the local council website:
Bulleen Park provides important community facilities including sporting ovals, an aeromodellers field, archery field and playground. It also accommodates some informal recreational open space along the Yarra River, particularly for walking and bike riding.
