If you're a resourceful visitor, pack a hamper of crusty bread, tasty cold meats, marinated olives, a cheese or two and a bottle of local wine, and take your picnic to a secluded cliff-top to enjoy the spectacular sea views.

Popular sites include The Salopian Inn at McLaren Vale, the famous Victory Hotel at Sellicks Beach, The Flying Fish Caf on the foreshore at Horseshoe Bay, The Mill at Middleton and The Reef on Granite Island in Victor Harbor.
