U nlike the London Underground which is rather easy to navigate, the Paris Metro is a web of intrigue.
Some lines go underground three levels.
Each time I visit, it seems to have grown organically. O ne stop on the RER took me to Chatelet. From there, I dragged my suitcase through a maze of tunnels to catch the new line, the Number 14 to Biblioteque. T he see-through train carried us at lightning speed through the huge new tunnel. The glass ceiling, glass windows, and glass doors made the entire experience expansive.
