The Dorrance River, originating from the Adelaide Hills, is 85 kilometers long, crossing the Adelaide Plain, across the Central Business District of Adelaide, and reaching Henley Beach (Henley Beach). The Torrens River divides Adelaide into two contrasting areas: the north and the south are quiet and beautiful residential areas, and the south is a lively and prosperous business district. There are many fish in the river, including not only Australian fish species, but also many imported and farmed from abroad, so it becomes the best choice for fishing. In the hot summer, many people like to choose to sit in the shade of a tree and fish on the green lawn, self-cultivation and self-contained. On the banks of the Dorrance River, you can often see flocks of black swans and wild ducks. They become good friends of anglers and are allowed to pet them. On the banks of the Dorrance River, a quiet, forested trail has been built. Visitors can ride bicycles or stroll freely, admire the riverside scenery and various flora and fauna along the way, integrate into the local cultural life, and enjoy the leisurely experience of traveling.
