The Alphen Trail is a popular greenbelt walking path located in the Constantia Valley of Cape Town. It follows the Diep River, winding through a mixture of oak-lined paths and indigenous riparian vegetation. The trail connects the Alphen Hotel area to Constantia Main Road, providing a flat and accessible route for pedestrians. It serves as a vital corridor for local birdlife, including kingfishers and owls. The path is situated within the Alphen Common, a public space maintained by the City of Cape Town. It is a shared-use space frequently utilized by residents for jogging, dog walking, and family recreation. The trail crosses several small bridges over the river, which remain the primary features of the route. As of July 2026, the area remains open to the public as a natural municipal park.
