I m very thankful if someone can suggest how to make Ch. De Gaulle, Paris(CDG), Terminal G to Eiffel tower and back toCh. De Gaulle, Paris(CDG), Terminal G in lay over of 5.5 hour at Paris
Traveling from CDG Terminal 2 to Eiffel Tower is 1 hour 10 minutes, one way, not including walking time from your baggage carousel to the train station.
If you think you have enough time, the route is RER B train from CDG Terminal 2 train station to Denfert-Rochereau, transfer (use same RER ticket) to Metro line 6, direction Charles de Gaulle-Etoile until Bir-Hakeim station, walk the rest of the way.
