The southernmost point of the Australian mainland, Wilsons Promontory (affectionately known to Victorians as 'the Prom') is arguably the most loved national park in Victoria. Its 130 km coastline is framed by granite headlands, mountains, forests and fern gullies. Tidal River, 30 km inside the park boundary, is the focus for tourism and recreation. The park contains the largest coastal wilderness area in Victoria.
