St Mary Inlet Campground sits near the mouth of St Mary Inlet within Fitzgerald River National Park, Western Australia — country recognised as belonging to the Goreng, Menang, and Wudjari peoples.

The campground offers a direct track to the beach, where southern right whales can be observed sheltering in the bay with their calves during winter months. Facilities are basic, with toilet access available on site.

Campfires are not permitted, in line with national park rules across Western Australia. Campers should arrive self-sufficient for drinking water, as none is available at the site.

Park entry and camping fees apply, and the site operates on a non-bookable, walk-up basis.
