The Coast to Vines rail trail is a rail trail in the Australian state of South Australia following the course of the disused Willunga railway line in the southern suburbs of Adelaide.

It is open to pedestrians and cyclists, and runs for 34 km from Marino to Willunga.

A short distance away are Hallett Cove shops, where it crosses Lonsdale Highway and proceeds through a picturesque area of Trott Park.

The former railway line stations were Patpa, Happy Valley, Reynella, Coorara, Morphett Vale, Yetto, Hackham, Korro, Noarlunga, Moana, Tuni, McLaren Vale, Pikkara, Taringa and Willunga.

[1] The trail was completed in 2007, with a small section running along the main street of McLaren Vale.
