Eurotunnel operates the Channel Tunnel; it also holds the concession for the tunnel until 2086.
Via the Channel Tunnel, you can travel as a rail passenger between St. Pancras station in London and Paris, France, and the Belgian capital, Brussels. Other continental destinations include Disneyland Paris, Lille, Avignon and some Alpine ski resorts. You can also take your vehicle through the tunnel between Folkstone and Calais on one of the specially designed trains.
The Eurostar trains reach speeds of around 300 km per hour (186 miles per hour), meaning that the journey time between London and Paris is 2 hours, 15 minutes, while traveling between London and Brussels takes 1 hour, 51 minutes. If you're traveling with your vehicle, expect the journey time between Folkstone and Calais to be around 35 minutes.
