The Friends of Willunga Basin have spent several years working on a concept trail in the Willunga Basin.
The 100km 6-day loop trail could be hiked using overnight stays in nearby accommodation. The route takes in Kangarilla, Willunga, Sellicks, Aldinga, Maslin Beach, Seaford Heights, McLaren Vale, the Onkaparinga River National Park.
They have been in discussions with the City of Onkaparinga since 2012. They have a walking group which walks the trail regularly, determining its suitability. Public consultation has yet to take place before waymarking can go ahead. This will include at least two easements on private land to be negotiated as well as some trail improvements.
