The Underground Maze Decoded

Châtelet-Les Halles is massive and confusing, but it's the key to efficient Paris metro travel. Here's how to navigate it like a local:

Best Connections:

• Lines 1, 4, 7, 11, 14 + RER A, B, D all connect here

• From Line 1 to RER B (airport): follow signs for 'Sortie 3-4', then RER signs

• Line 4 to Line 14: stay underground, follow 'Correspondance' signs

Time-Saving Tips:

Use the moving walkways - they're faster than you think. The station spans several blocks underground, so check which exit you need before descending. Exit 7 gets you to Forum des Halles shopping, Exit 3 to Rue de Rivoli.

Avoid rush hours (8-9am, 5:30-7pm) unless absolutely necessary. The crowds are genuinely overwhelming.
