Twelve Mile Delta Campsite is a DOC-managed campground set on a gravel river delta at the outlet of Twelve-Mile Creek, near the shores of Lake Wakatipu, about 12 kilometres west of Queenstown along Glenorchy Road.

The road is sealed to the delta, with narrow gravel roads around the campsite itself. Regenerating native forest surrounds the area, and the setting offers spectacular views across the lake and surrounding mountains.

The campsite accommodates up to 100 tent sites and is a popular spot for boating, swimming, fishing, picnicking, and mountain biking. Toilets and water are available on site. The DOC Campsite Pass is not valid here.

The site also holds a place in film history, having served as the Ithilien Camp location during the filming of the Lord of the Rings trilogy.
