There aren't many Parks Victoria-run camping spots by the beach within a two-hours drive of Melbourne (commercial caravan parks not included). Bear Gully Campground with its spectacular views of Wilsons Prom 60km to the southeast happens to be one of them.
The Bear Gully campground is located at the end of Bear Gully Road, towards Walkerville South. The dirt track leading in to the campground is gravel with regular grading. Most 2WDs driven sensibly will make it in with no problems.
