Maslin Beach is a long, straight shore beach approximately 7.3 kilometers in length, located within the City of Onkaparinga on the Fleurieu Peninsula coastline. The beach is public with amenities and is situated adjacent to a road, facilitating access. Parking is available, and the beach is located within a settlement. The foreshore features geologically significant rugged red cliffs that provide a striking contrast to the water, offering scenic views from both the sand and the coastal walking trail above. The northern section of the Coast Park Trail runs for about 1.5 kilometers along these cliff tops, providing several beach access points for paddlers. The southern end of Maslin Beach is designated as a nudist beach, while the remainder of the beach is dog-friendly. For paddlers launching from shore, the carry distance from parking to the water's edge is typically short due to the adjacent road and foreshore access. The beach faces Gulf St Vincent, making it exposed to prevailing winds and swell from that direction, which can create surf and shore-break conditions. The beach is known for its raw dune landscapes and is generally uncrowded. From Maslin Beach, paddlers can access nearby coastal destinations. The Coast Park Trail plan indicates a conceptual link along the foreshore, and consultation has taken place on a trail section that would connect Maslin Beach to Port Willunga and Aldinga Beach to the south. Paddling north along the coast leads towards Christies Beach and Port Noarlunga. The water quality and general cleanliness of the beach are considered good, with the area noted for its picturesque and pristine appearance.
