Loch Katrine Campsite is a free, basic Department of Conservation campsite situated on the southeast shore of Loch Katrine within Lake Sumner Forest Park, Canterbury.

The grassy camping area accommodates up to 30 tent sites on a first-come, first-served basis, with basic toilet facilities and water available. No fires are permitted at any time.

The surrounding area offers walking, mountain biking, and 4WD tracks, and the lake itself is popular for swimming — though the water is notably cold — as well as fishing and boating.

Loch Katrine also serves as a launch point for accessing nearby Lake Sumner by boat. Sandflies can be a nuisance, so insect repellent is recommended. Access is via SH7, turning off at Waikari toward Hawarden and then following Lake Sumner Road.

The final stretch to the campsite is a rough, approximately 8 km road requiring a four-wheel-drive vehicle with good clearance. Dogs are permitted on a leash.
