The Darby River is a perennial river located within Wilsons Promontory National Park in Victoria's South Gippsland region. It flows through a protected coastal landscape, offering a paddling experience described as having a mystic feel, particularly near its mouth. The river is accessible from the Darby River Carpark, which serves as a key access point. However, paddlers should be aware that the boardwalk at this location is currently closed to public access. The river provides opportunities for both inland upstream exploration and paddling to the river mouth. The surrounding area features expansive beaches, such as Darby Beach, which is a short walk from the carpark, and a wind-swept coastal landscape near Tongue Point. As the river is situated within a national park, paddlers must comply with all park regulations, which may include obtaining permits in advance from the Tidal River Visitors Centre for certain activities. The area is part of a significant hiking network, with trails like the one from Darby River to Darby Saddle via Tongue Point covering considerable distance and elevation, indicating a rugged and undeveloped environment.
