The closest country to visit from the UK is France. The two nations are separated by the English Channel, with the shortest distance being just 21 miles (33 km) between Dover in Kent and Calais in northern France. This proximity makes France the most accessible foreign destination for UK residents, reachable in just 35 minutes via the Eurotunnel "Le Shuttle" from Folkestone, or about 90 minutes by ferry from Dover. The Eurostar high-speed train also connects London St Pancras to Paris in just over two hours. After France, the next closest countries are Belgium and the Netherlands. While the Republic of Ireland is also very close and shares a land border with Northern Ireland, France remains the "nearest" in terms of the closest geographical point between the British mainland and the European continent. This ease of access has made "day trips" to the French coast for shopping or dining a popular cultural staple for those living in the southeast of England.
