The thing everyone gets wrong about the Chunnel

People compare the Chunnel to flying.

That’s the wrong comparison.

The real comparison is this: city centre to city centre. No airport transfers. No liquids bag. No arrivals hall purgatory.

When you factor in security, boarding, baggage reclaim and transport from Charles de Gaulle, the Eurostar through the Channel Tunnel is usually 3–4 hours faster door‑to‑door than flying.

What the Chunnel actually is (and why it still matters)

The Channel Tunnel – usually called the Chunnel – is a 50.45 km railway tunnel running between Folkestone, Kent and Coquelles, near Calais.

Here’s the part most people don’t appreciate: 37.9 km of it runs under the seabed, making it the longest undersea tunnel on Earth. At its deepest point, you’re 75 metres below sea level.

It opened on 6 May 1994. More than three decades later, it remains the only fixed link between Britain and mainland Europe.

London to Paris in 2026: the exact journey

This is how the journey works today, not how blogs described it years ago.

  • Departure station: London St Pancras International, Euston Road, London N1C 4QP
  • Arrival station: Gare du Nord, 18 Rue de Dunkerque, 75010 Paris
  • Fastest journey time: 2 hours 15 minutes
  • Typical frequency: 14–16 trains per day
  • Operator: Eurostar

Trains run every 60–90 minutes from early morning until evening. There are no overnight services.

Check‑in rules that can ruin your day

This is where most people slip up.

Because the UK is outside Schengen, passport control happens before boarding. Miss the cut‑off and the train leaves without you.

  • Standard / Standard Premier: arrive 75 minutes before departure
  • Business Premier: arrive 45 minutes before departure
  • Gate closure: 30 minutes before departure (15 for Business Premier)

Once you’re through security and passport checks, that’s it. You step off the train in Paris and walk straight out.

Luggage, pets and bikes: the 2026 rules

Luggage: No weight limit. You must be able to carry it yourself.

  • Standard / Standard Premier: 2 large bags (max 85 cm) + 1 small item
  • Business Premier: 3 large bags + 1 small item

Pets: Pets are not allowed on Eurostar services to and from London. The only exception is registered guide or assistance dogs, which must be booked in advance.

Bikes: Folding bikes (folded under 85 cm) travel as luggage. Full‑size bikes must be disassembled and packed, or transported via specialist services.

Arriving in Paris: why Gare du Nord is an advantage

Gare du Nord isn’t pretty. It is practical.

You arrive in the 10th arrondissement with immediate access to:

  • Metro lines 4 and 5
  • RER B to Charles de Gaulle Airport
  • Direct trains to Brussels, Amsterdam and Lille

You’re standing in Paris, not waiting to get there.

Conclusion: the Chunnel isn’t the journey – it’s the advantage

At the start, it sounds like a novelty: a train under the sea.

By the end, you realise what it actually is: a strategic shortcut between two capitals. No wasted transfers. No dead time. Just momentum.

Once you’ve done London to Paris on the Chunnel properly, flying starts to feel like the long way round.
