Calais (Dutch: Kales) is a city in the Nord-Pas de Calais region of France. It is the closest point on the French mainland to England; Dover lies across the English Channel (La Manche) just 32 km away. The town has a major cross-Channel ferry port, and the French entrance to the Channel Tunnel is nearby. Calais is popular with British day-trippers arriving by ferry or on Channel Tunnel shuttle trains one reason being due to the fact that France has lower taxes on alcohol and tobacco. Large warehouse supermarkets have sprung up on the outskirts of Calais just to serve these British "booze cruisers" who return to the UK with their suspensions groaning under the weight of cheap alcohol and cigarettes. While most tourists view the town as simply a port, there is more than that.
The strait of Dover is one of the most frequented shipping lanes in the world. Calais ferry port allows easy access to the town itself as well as shops outside the town, many of which are designed to sell alcohol to visitors from the UK where higher taxation means alcohol of all kinds is normally priced higher.
Free car parking facilities are available in front of the Calais ferry terminal and the maximum stay is of three days.
The port is also directly linked to the French motorway system. The A26/E15, which provides access to the heart of France including Paris and beyond and the A16/E40, a gateway to Benelux and the northern European motorway systems. The A16/E402 directs you to western France.
Ferry crossings from Dover to Calais take typically around one hour and fifteen minutes with it normally recommended that passengers arrive at least an hour prior to departure, but operators' advice may change. Two operators operate this route: P&O and Seafrance. P&O is a British operator while Seafrance is French. However, the port of Dover is not connected only to Calais. Another popular route is Dover to Dunkirk, and this route is operated by Norfolkline ferries which has recently become part of DFDS Seaways.
Eurostar operates trains between Calais Fréthun station and the following destinations in the United Kingdom and Belgium:

Passengers travelling by Eurostar from the UK to Calais go through French passport/identity card checks in the UK before boarding the train, rather than on arrival in France. Passengers travelling in the other direction from Calais to the UK by Eurostar go through UK passport/identity card checks in Calais Fréthun station before boarding the train, and UK customs checks on arrival in the UK.
Those travelling by Eurostar between Brussels and Calais are within the Schengen Area.
Although the Brussels Midi-Calais Fréthun route can't be purchased on the Eurostar website, it is available on the Belgian Railways website 
Eurotunnel Le Shuttle
Running from Folkestone to the western edge of Calais (Coquelles), this car shuttle service operated by Eurotunnel takes about 35 min (although only about 20 min in the tunnel) and offers the fastest way to travel between France and the UK. This train service is for passengers with cars only, who remain with their car for the duration of the short trip, as there are no restaurants (except a fast food restaurant) but there are toilets.
Passengers travelling from Folkestone to Calais go through French passport/identity card checks in the UK before boarding the train, rather than on arrival in France. Those travelling in the other direction from Calais to the UK by Eurotunnel go through UK passport/identity card and customs checks in Coquelles before boarding the train, rather than on arrival in the UK.
Cars can be taken to the south of France, destinations such as Narbonne, Marseille and Lyon can be reached by train (your car is carried with you).
Most people travel by car around the town, but there is a comprehensive network of buses running from the town centre to the suburbs and Cité Europe. The port is served by a special shuttle bus although via a footbridge the centre, and the harbour terminal are only 15 min apart.
Bus 5 is useful for reaching the large Auchan and Carrefour hypermarkets and the Cite Europe shopping mall and the 6 goes to Calais Frethun Eurostar station. Services run every 30 min during the day and costs about €1 (board through the front door and pay the driver) and all buses terminate outside the Gare D'Ville.

Cite Europe - Large shopping centre containing 147 shops, 20 restaurants, and a cinema. Located next to the Channel Tunnel terminal (Junction 41 or 42 on the A16). Note that the shops are closed on Sundays and none of them sells tobacco.
Alcohol – since France has slightly lower taxes on alcohol than the UK various establishments have set up to cater for day trippers, although often it is a little cheaper to go to a local hypermarket (and you can pick up other stuff). The main hypermarkets are Auchan and Carrefour, the latter within the Cité Europe shopping centre and can both be reached on bus 5. In the town centre, there is a smaller Carrefour located at the back of the Quatre Boulevards shopping centre (near the Opéra).

To hitchhike to Belgium or the Netherlands, if you leave the terminal, you must walk 500 m through a large car park, after which you will see roundabout and an on-ramp to the motorway. That is the place to hitch a ride: there is enough space even for a big lorry.
For a more 'traditional' experience of France, Saint-Omer is a mere 26 miles (43 kilometres) down the road from Calais. The Saturday morning market on the main square, the Place Foch, can be enjoyable. There are also good affordable restaurants and friendly bars, as well as interesting architecture.
