We are visiting Paris for two days in June. What should we definitely visit in this short time?

Most people are going to tell you that it depends on your interests! What sorts of things do you like? There are endless things to do in Paris, so you'll need to narrow it down for us a bit I mean, I could tell you what I would do, but that stuff may not interest you at all.

Tow days is a very short time for Paris. You will have to do a lot of research, using guidebooks and the internet to be sure that you have a good idea of what appeals to you and won't miss important things. You might start with the destination guide for Paris here on Fodors. Look at some trip reports on this forum.

It would help us to help you if you gave us a little information on why you are going to Paris and your interests (parks? museums? architechture?, churches?, shopping?, fine French cuisine?, etc.)

For this sort of very general information you don't need us. Consult Fodor's travel guides at the top of the page, like here:

Notre Dame and the Musee d'Orsay.

Cluny Museum
Luxembourg Gardens
Pere Lachaise Cemetery
Ste-Chapelle

Not into shopping at all. Art,architecture,gardens,history. Will definitely try to get to the main landmarks, but where should we spend time?

A walking tour is good. Paris Walks has been around a long time, they use certified guides, have interesting and informative walks.

There's about 30 museums devoted to art. You'll need to read about some of them and choose what type of art you like.

Thank you, will be reading a lot before we go.
