Tennyson Beach is a wide, sandy beach forming a picturesque coastal stretch within the City of Charles Sturt, South Australia. It is a direct continuation of Semaphore Beach to the north and Grange Beach to the south, creating a long, connected shoreline. The beach is bordered by the unique Tennyson Dunes Conservation Park, which features natural dune habitat and bushes. The overall atmosphere is serene and less developed than some neighboring beaches, offering a sense of seclusion ideal for a peaceful fishing session. The beach is wide and flat, with a notable presence of seaweed along the shore. It fronts the waters of Gulf St Vincent.
