Loch Katrine Campsite is a free, basic DOC campsite set beside the lake in Lake Sumner Forest Park, Canterbury. The grassy camping area accommodates up to 30 non-powered tent sites on a first-come, first-served basis.

Facilities include non-flush toilets and a water supply (untreated — boil before use). Open fires are not permitted. Dogs are welcome on a leash.

The site is well suited to outdoor activity, with opportunities for walking, mountain biking, and 4WD exploration in the surrounding area. Swimming in the lake is popular, though the water is notably cold.

The campsite is accessible to off-road caravans and four-wheel drives, reached by turning off State Highway 7 at Waikari and following Lake Sumner Road. Three huts in the area are separately managed by the Loch Katrine Association and available for booking.
