Yadboro Flat is a free campsite on the upper Clyde River in New South Wales, situated within or adjacent to Morton National Park on the South Coast.

The site sits near the confluence of the Yadboro River and the Clyde River, surrounded by the Budawang Wilderness Area, with Pigeon House Mountain, Byangee Walls, and The Castle all within reach, making it a popular basecamp for bushwalkers and wilderness explorers.

The campsite features a large grassy area with direct river frontage, offering swimming, fishing for Australian bass, and paddling in the calmer stretches of water.

Access requires a long dirt road drive — roughly 45 minutes to an hour from Milton or the Kings Highway — and while the road is generally manageable, conditions can deteriorate after rain and a 4WD may be needed to travel beyond the flat toward walking tracks.
