Lower Plenty The meeting of the Yarra River and The Plenty River form the Southern and Western boundaries of this delightful area. There are parklands and walking tracks along the banks of both rivers making this an idyllic environment. Much of this area features large elegant properties many of which overlook the extensive parklands, the Yarra River and beyond to the city skyline. Lower Plenty is home to The Heidelberg Golf Club and abuts the Rosanna Golf Club.
