Deer Flat Campsite is a DOC standard campsite in Fiordland National Park, situated along the West Branch of the Eglinton River about 62 km north of Te Anau on Milford Road (SH94).

The site occupies a broad, grassy flat framed by small pockets of beech forest, with open mountain views across the valley. It is a popular spot for fly fishing in the river. The campsite offers 15 non-powered tent sites and requires advance booking.

Basic facilities include wheelchair-accessible toilets. Fires are permitted only in designated fireplaces and subject to any active fire ban. Dogs are not allowed.

Note that the low-lying location makes the site susceptible to flooding after heavy rain, so conditions are worth checking before arrival.
