Courthouse Flat Campsite is a DOC-managed campground set within Kahurangi National Park, reached via a scenic drive through the Tadmor Valley and Wangapeka River Road — roughly an hour south of Tapawera.

The access road narrows considerably and can become impassable after heavy rain; large campervans are not recommended. The site sits beside a creek near a historic goldfield, with a toilet, picnic benches, and information boards on-site.

No fires are permitted at any time, and water is sourced from the stream. Nearby activities include walking, fishing, gold panning, hunting, and caving.

The campsite also serves as a popular starting point for the Mount Owen track and a loop walk combining the Mount Owen and Blue Creek Tracks.
