Routeburn Flats Campsite is a walk-in Great Walk campsite set in the Route Burn valley within Mount Aspiring National Park, Otago. It sits adjacent to the Routeburn Flats Hut near Emily Creek and is accessible only on foot via the Routeburn Track, roughly 1.

5 to 2 hours from the Routeburn Shelter road end. The campsite offers 15 non-powered tent sites with open valley views. Campers must carry all their own gear, including tent, sleeping bag, and cooking equipment. Fires are not permitted at any time.

During the Great Walks season (November to April), advance bookings are required; outside that period, sites are available on a first-come, first-served basis. No dogs are allowed.
