Concordia can be reached:

• by tractor trains from Dumont d'Urville: about 3,000 tons of cargo has delivered by tractor trains during the construction phase - which become 4,000 tons with the EPICA deep drilling associated project - while routine operation requires the annual delivery of some 400 tons. Having in mind cost and impact of man on the environment, an efficient, relatively low polluting, regular long-range surface transport system (traverse) was developed between Dome C and Dumont d'Urville-Cape Prud'homme, a return trip close to 2,300 km.
  Heavy cargo is shipped by sea from Hobart in Tasmania to Dumont d'Urville then transferred to Cape Prud'homme, either over the sea-ice in winter or on barges over the water in summer. Cape Prud'homme, a nearby coastal site with easy access to the plateau, is the convoys' formation area where a base camp has been set-up to support traverses. The traverse system is fully operational with three return trips conducted every summer season between mid November and mid February and it takes 19 to 25 days.
• by ski equipped planes: personnel and selected light cargo are transported to and from Dome C by a ski equipped Twin Otter aircraft operating out of Mario Zucchelli Station at Terra Nova Bay on the triangular route Mario Zucchelli - Dome C - Dumont d'Urville. Air transportation is mostly suitable for cargo sensitive to low temperatures and to mechanical stress. Travel in and out of Antarctica for Dome C personnel is primarily by air between Christchurch in New Zealand and either Mario Zucchelli or McMurdo station and secondarily by sea between Hobart in Tasmania and Dumont d'Urville.
