๐ Alternative Routes
Ferry + Train (~7-8 hours)
Ferry from Dover to Calais (1.5h), then train to Paris. Total ~ยฃ50-80. Good for those wanting to see the Channel, or if traveling with a car.
Flight (1h flight + airport time)
easyJet/Ryanair from ยฃ25, but total 4-5 hours with airports. Getting from Heathrow/Gatwick to city center adds up. Eurostar's city-center-to-city-center wins.
FlixBus Coach (~7-9 hours)
ยฃ15-30, includes ferry crossing. Very slow but cheapest option.

โ FAQ
How long is the train from London to Paris?
Eurostar direct takes about 2 hours 16 minutes from London St Pancras International to Paris Gare du Nord. The Channel Tunnel crossing takes ~35 minutes. Around 12-18 daily services.
Do I need to pay extra with a Eurail or Interrail pass?
Yes, pass holders pay a โฌ30 reservation fee (Eurostar passholder fare, 2nd class). Pass holder seats are limited and can sell out weeks ahead on popular dates. Note: Eurail Pass does not cover other UK trains.
How early should I book for the cheapest fare?
Tickets open 3-4 months ahead, from ยฃ52 one-way (Standard). 6-8 weeks out is typically ยฃ60-90. Last-minute can be ยฃ150-250+. Midday weekday trains are usually cheapest if you're flexible.
How early should I arrive at the station?
Officially 90 minutes early, but 60 minutes is usually fine. You'll go through security, passport control, and UK exit/French entry checks. Weekends and holidays may have longer queues โ allow extra time.
Which side has the best views?
Honestly, most of the journey is either in the tunnel or through suburbs. The Kent countryside (left side) has some nice English pastoral views. The tunnel is 35 minutes of darkness. French side is flat northern plains. This train sells on speed and convenience, not scenery.
