Dry Creek is an ephemeral stream, meaning that it flows during winter months and usually dries up in summer, leaving only a few shallow pools. The Dry Creek catchment extends into the Mount Lofty Ranges and covers an area of over 100 square kilometres. Dry Creek travels some 28 kilometres before it flows into the Barker Inlet as Swan Alley Creek. The historical Dry Creek Linear Park forms a secluded nature corridor along Dry Creek, extending 3.5 kilometres from Walkleys Road to Bridge Road. Picturesque trails wind through the park and link with Founders Reserve on the eastern side and the Stockade Botanical Park on the western boundary. Along the creek the River Red Gums are a haven for numerous bird species and hollows in trees are home to bats and brushtail possums. Golden Wattles are scattered along the banks, complemented by the weeping branches of Willow Wattles. The pools and reed beds attract a variety of bird species, while frogs inhabit the grassy banks, reed beds and mud along the creeks. In addition, historic buildings and structures within Dry Creek Linear Park date back to the early years of the Adelaide Colony, having survived from the days when the quarries were worked by inmates of the nearby Yatala Prison. In recent years, the City of Salisbury has completed a number of restoration programs at the park, including the Yatala Powder Magazine, the Blacksmith's Shop, several guard lookouts posts and a cottage which remains on the former RM Williams property. Car parking, toilet and picnic facilities are available, as well as electric barbecues located at the Stockade Botanical Park
