The Chadwick Lakes are located on the NorthWest side of the island, between Rabat and Mtarfa. They were formed by Osbert Chadwick, a British engineer who built a series of dams, which allow rainwater to gather in the wet season, thus resulting in artificial freshwater lakes, forming a miniature ecosystem with all kinds of different flora and faun, namely protected tadpoles and frogs.
Families and friends frequent the valley during winter or spring as unfortunately the warm Summer months tend to dry-up the lakes.
