Arc-sur-Tille is a French commune in the Côte-d'Or department in the Burgundy region of eastern France.
The inhabitants of the commune are known as Acétillois or Acétilloises
Arc-sur-Tille is located approximately 12 kilometres by road east of Dijon by road D70 which continues north-west to Magny-Saint-Medard. The A31 autoroute passes through the west of the commune from north to south with exit 4 in the commune west of the town. The commune can also be accessed from Remilly-sur-Tille in the south by road D34 which continues north to Chateau d'Arcelot. Road D961 also goes east from the village to Étevaux. Apart from the large sized village occupying some 15% of the commune, the rest of the area is almost entirely farmland.
The commune is located on a marshy plain
The commune is traversed from north to south by the Tille, a tributary of the Saône. It has often flooded in the past, overwhelming and damaging the village and crops.
The Lake of Arc-sur-Tille, west of the town, is a former gravel pit converted since 2002 to create the largest sandy beach in Burgundy. It is very popular in summer with swimmers and it allows many water activities (sailing, canoeing, water skiing and fishing basins reserved). The lake water is of excellent quality.
