limited time in paris

Have you any specific things in mind? Seeing things? Visiting a museum?

Eiffel tower is top of my list. Rest not sure but not interested in museums

maybe a good place for lunch

Have a leisurely walk to the Eiffel Tower, picking up some Parisian atmosphere on the way and allowing you to have a look at the Notre Dame and the Louvre. You've got after all six hours. ViaMichelin gives excellent detailed maps.

I'm planning to book a ticket till 2nd floor of Eiffel tower for May visit. how much approx time will it take to visit the tower? i heard lines can be really long. Also, Is it worth eating at Tour Eiffel Restaurant? And how about the stroll at champs elysees?

It would make me nervous to do things with all kinds of complicated timing restraints.

I would neither book a ticket to the 2nd floor nor plan to eat there. It might be possible in, say, February, but if you're going at a busy time of year, it might not. Instead of going UP the Eiffel Tower, get yourself to the Tour Montparnasse, go to the top, have a wonderful view of all Paris, including a view of the Tour Eiffel, have a drink and snack at the bar and call it a day. In all likelihood, you will not have time for what you wish to do.

hi, thanks for Tour Montparnasse suggestion. looks good. is there a skip the line option available at Eiffel tower? if i reach Eiffel tower by 10.30 am, i'll have good 5 hours with me, isn't it enough? i really want to visit Eiffel tower. who knows when i'll visit Paris again.

You can visit the Eiffel Tower without going up. I also recommend Tour Montparnasse. I did not go up the Eiffel Tower until my fifth trip to France, glad I did, but would never do it a second time. You don't have enough time in the city to do that. The line to go up is long and what most forget is that the line at the top to come back down is also very long.
When I did go up the Eiffel Tower I was there about half an hour before it opened and the line was small.
