Port Road, between Aldinga and Port Willunga, is edged with lines of Aleppo Pines (Pinus halipensis). This avenue of trees was planted by the pupils of Aldinga Primary School in approximatey 1907-8, and created a shaded walkway for some of the distance to the beach. The headmaster at the time was Mr W.A. Thompson.
The avenue is an important Aldinga/Port Willunga landmark and the pines appear in several of the paintings of Horace Trenery of around 1945.

Information on this tree planting was given by Mr William (Bill) Howe (now deceased), a fisherman of Port Willunga who was a pupil of the school at the time and participated in the planting project.
