Lake King William Campground is a bush camping area situated within the Franklin-Gordon Wild Rivers National Park, part of the Tasmanian Wilderness World Heritage Area.

There are no facilities on site, so campers must be fully self-sufficient, bringing their own drinking water, food, and a portable toilet. Pets are not permitted. The site is free to camp, though a Tasmanian Parks Pass is required.

It is a Fuel Stove Only Area year-round, meaning campfires are prohibited to protect the region's natural and cultural heritage values — breaches can result in a substantial fine.

Access may be challenging for large vans due to a narrow entry road and limited turning space. There are two camping areas near the lake, with one located approximately 1. 8 km south of the Derwent Bridge hotel. A maximum stay of seven days applies.
