Paris, tu me manque..10 days in spring

Have you been to the Jacquemart-Andre Museum? We finally hit it on our 4th trip to Paris and loved it.

If you can find it, the book "24 Great Walks in Paris" will get you into some less-frequented corners of the city with a focus on architecture and neighborhoods.

We visited the Pere Lachaise cemetary on our arrival day to Paris. It was nice to be able to get some exercise after the overnight flight from the U.S.

This book/card collection has some great walks. Many are short but if you take the general descriptions and do some digging for info about the sites before you go I find you can really get a sense of the areas.

I second the suggestions of the Jacquemart-Andre Museum - fyi there is a Mary Cassat exhibition on until the end of July. The cafe is amazing.

Arenes de Lutece. It's a Roman amphitheater, near the Pantheon, that is often overlooked. It's in pretty good shape. Today it's mostly a park/picnic spot for locals eating their lunch while kids play soccer on the floor.

Though you are not museum fans, as you say, think about and check out the Musee des Arts Decoratifs. It is part of the Louvre but the entrance is on Rivoli. Wonderful exhibits of furniture design, couture design etc., from past and present. Never crowded (I know not why) and not overwhelmingly large. A pleasant couple of hours can be spent there.

Take a look at the Paris listings at the Atlas Obscura website. They always have lots of suggestions for obscure museums/sites that you can add to the more conventional ones.

You may have already done it, but if you haven't walked the promenade plantée, that's very enjoyable. Bonus if you hit it on a day the market is going at the Bastille--you can pick up lunch, wander along the greenway for a bit, and then eat it at either Jardin de Reuilly (there's a water fountain here that dispenses sparkling water!) or continue all the way to Bois de Vincennes.

The promendade plantee doesn't go all the way to the Bois. It's stopped by Blvds. Poniatowski/Soult and the Peripherique. To get to the Bois one has to walk Ave. Daumesnil to Porte Doree and into the park. Not very far but disconcerting to those who are expecting a direct link where there isn't one.

I had a fabulous tour last year with Paris Greeters - I had requested a focus on architecture and the guide took me all around the 14th. It was wonderful! On my list for next trip is a self-guided tour of some of the Art Nouveau buildings; if you search for Art Nouveau walks on Trip Advisor, you'll get some good info.
