Paris sightseeing

We loved The Promenade de Plantes, a fine walk and, in our experience, uncrowded,

Paris by Mouth has wonderful tours https://parisbymouth.com/food-wine-tours/. Small groups, great guides.

I enjoyed the Musee Carnavalet on my last visit (my 4th). We also visited several farmers/artists markets.

book a concert at the Philharmonie -- amazing building so go early and head for the roof and just appreciate the building.

We enjoyed a cheese class at https://parolesdefromagers.com/en/formation/introduction-to-cheese-and-wine/
In addition to enjoying the cheese and wine we explored some very interesting architecture near here.

We also did a wine tasting at O Chateau but while the wine was generous and good and the add on cheese platter generous the instructional component was a bit laughable.

If you haven't walked the Promenade Plantee, it is worth doing on a nice day -- and in fact the parks of Paris are all nice destinations. Years ago we spent two weeks in an apartment in the Latin Quarter going to a different Paris park each day and having a picnic and reading. It was a lovely trip.

I agree about the promenade des plantes and the Jardin des plantes also. If you haven't been to them before both the Cluny and Carnavalet museums are definitely worth the time. Search for a list of all the museums in Paris and see what strikes your fancy, there are so many small unique museums there. I also enjoyed exploring the cemeteries- Pere Lachaise and Montmartre were my favorites. Ride the metro and stroll around a neighborhood you haven't been to. That was one of my favorite things to do.

At the risk of being pedantic, but so you know what you're looking for, it's not the Promendade des Plantes. There is no such thing.

You're looking for the Promenade Plantée, also known as the Coulée Verte. It runs from behind the Opéra Bastille down toward Vincennes with exits all along the way.

The Jardin des Plantes is a separate thing entirely, but well worth a visit.

Cluny Museum
Rodin Museum and Garden
St. Denis Basilica

You have been to Ste. Chappel, I assume. If not, be sure to go!

Add the Marmotten Museum of you are a fan of Monet or other Impressionists. It is also a really nice area of Paris that many tourists never see. I've walked from there to Tour Eiffel a couple of times, and it brings you right through the Passy area, which has some nice sights and markets.

Question for those who have visited the Cluny in the last 2 months - Are all the rooms open?

I visited in late October - about half (or more of) the rooms were closed, full price charged for admission. This was noted at the entrance, but I didn't realize the extent of the closures. Worth it to me to see the Lady and the Unicorn room (again), but I heard many complaints in English, French, and German as various visitors realized how little was open for viewing. I am not quite certain why rooms were so restricted - whispered rumor was staff number difficulties. If closures are still on, I am not certain it is a good time to visit the Cluny - really not much available to view on my visit.

Other ideas:
For literary types - Maison de Balzac and Maison de Victor Hugo.
Musée Jacquemart-André
Basilique cathédrale Saint-Denis in St Denis - burial spot of French Kings edit - Oops noted above....
Malmaison - Napoleon's "gift" to Josephine in the Paris suburbs
National Ceramics Museum - Galerie de Sèvres (watch mid-day closing)
Musée des Arts Décoratifs (Period rooms, some excellent special exhibits)
The Liberation of Paris Museum - General Leclerc Museum - Jean Moulin Museum (WWII interests)
The Institut du Monde Arabe
Dior Galerie
Musée de la Musique in the Cité de la Musique

Have you toured inside the Pantheon? Spent time at the Musee de l'Armee?

Why are your interests? I know a number of other small museums - one hour or less for viewing - but not all would be interesting to all comers.

ORDtraveler,
So sorry to hear of the closure of sections at the Cluny. We were there at the end of May last year and got to see it all. It could easily be a 3-4 hour visit, and luckily there were frequent places to sit for these old folks. It's one of my favorite museums in Paris (along with the Rodin gardens)!

The bibliothèque Mazarine is a masterpiece, open to visitors and free. It's located on les quais not too far down from Notre Dame. No reservation needed. It isn't very well known and there typically aren't any visitors.

I also recommend checking out the Zadkine museum.

If you haven't done it yet, the well-known Hotel de la Marine offers an exceptional museum experience, with a world-class audioguide and a brilliantly curated selection of the Al-Thani collection.

In terms of tea rooms, there is a lovely one hidden in a courtyard not far from Notre Dame, off of la rue Dauphine. It's called l'Heure Gourmande. It's also always nice to stop in for a mint tea at the Mosquée de Paris, not too far from where you'll be staying either.

If you're in Montmartre, try to stop by l'Hotel Particulier for a mid-afternoon drink. The food is not worthwhile but the garden setting is just magical.

For restaurants check out Colvert, Jones, and le Verre Volé for example.

Best of luck and enjoy your trip!

The French Museum of Air and Space is fantastic and worth a day on it's own. https://www.museeairespace.fr/en/

We did O'Chateau ages ago and enjoyed it.

Also Cookin With Class has quite a few classes and we enjoyed the macaron one. I would love to do more of those!

If you go to Musee Jacquemart-Andre, try to make a reservation for the luncheon there. It is in a pictoresque room, and the food was good when we went there. Peter

I hope you have a great time! Here are the 2 different things we did on our last trip:

1) L'ALSACIEN restaurant in La Marais. It was delicious! The environment is great and the service a delight! Our server picked the greatest wine and told us all about where she was from. Lovely!

2) We took a food tour with Mat Mercer, our second, Napoleon Food Tour. We visited these much lesser known sites and food stops. My favorite was seeing a love letter from Napoleon to Josephine. It was amazing! He also has wonderful food and wine recommendations. I feel like he's our best friend in Paris!

The Basilica of St. Denis is a must if you are into churches. They say it is the first French Gothic, and as so often happens in the arts, they absolutely nailed it first try.

There is a museum in the Pasteur Institute dedicated to the great man. His tomb alone is worth a gander.

mrmet.pgr,
Re St Denis....It is the burial place of many French kings and queens,fascinating! We last saw it when we bookended it with a visit to Reims. There the cathedral is where nearly every king of France was crowned.

A lot of good ideas listed here, two I want to add- the Musee du Quai Branly- anthropological museum with a very impressive collection- and Serge Gainsbourg's house (need to book far in advance)- home to one of the greatest musicians of the 20th C, set up as when he lived there.

IMHO the Basilica St. Denis is the best often missed site on the Paris metro. It contains the tombs of the kinds of France which are works of art saved by some wise revolutionary when the bodies of the kinds were being trashed and dumped. If you haven't done that already definitely put that high on the list.

The old DK Eyewitness travel books had different two to three hour walks listed in them, some for sections of cities that you normally wouldn’t go to as a tourist.
I don’t know if they still produce travel guides or if those still have walking routes in them.
I copied some routes and used those to explore areas of cities and used them for Paris a few years ago.
It was great to see areas you wouldn’t think of going to otherwise.
I’m sure you could still find something like that.

You could also just get on random city buses and travel further out to explore.

Just wanted to add, if you go to Pere Lachaise cemetery, you can put specific graves into your Google Maps, and it will direct you there. I didn't know this until I was already exhausted searching, and a nice fellow tourist showed me. So I did get to see Jim Morrison's grave and Frederick Chopin's grave.

The ancient Roman ruins, Arènes de Lutèce, is near Notre Dame and off the beaten path. Further out, in the 18th, are Le Passe-Muraille (the man who walked through the wall--read the story first) and the Wall of Love. They are quite fun. Then you can just stroll around Montmartre. The museums that others have mentioned here are outstanding and quite manageable. It's too bad that Musée Nissim de Camondo is closed for renovations until 2026. I've been only once and wanted to return when I'll be in Paris in September.
We've enjoyed several restaurants near Notre Dame including Au Bougnat (just behind ND), Le Saint-Regis for lunches and Le Colimaçon for dinner (make reservations and ask to be seated on the top floor by the window, if possible--you will have to secure the reservation with a credit card). Btw, Berthillon is just a three-minute walk from Le Saint-Regis on Île Saint-Louis.
One of these days, I'll get to The American Library in Paris which is by the Eiffel Tower. The library supplied books to soldiers who were fighting in WWII at their own peril. (I need to pay my respect!)

If you are in to fashion or would like to see some beautiful designs, the Yves St. Laurent museum was very interesting. It was a good look into what the fashion houses look like, and they have his office set up as it was. Lots of his designs, and photos of back when including the super models he dressed. We really enjoyed it. https://museeyslparis.com/

I 2nd the Air & Space museum; there are 2 Concordes you can go on and an A380 as well. And if you have food at the restaurant, you can sit on the tarmac in front of the 747.

Also, if you're a fan of the new Mrs. Harris Goes to Paris movie, the exterior of the airport is in it.
