This will be a new area for us to explore. The 16th is mostly residential with many Embassies and high-end shops. There are many museums clustered around the Trocodero.
The Bois de Boulogne and Parc de Bagatelle have been on my list for years, but since it was so far out we never ventured that way. Now we will be on that side of the city and it is on the top of my list. We should be there in time to see the Iris Garden in bloom.
I do a lot of research before our trips, always trying to find something new and different to see and do. While doing my routine search, I came across this interesting site~Guided Photo Tours in Paris. Having a professional photographer take you on a personal tour with personal instruction sounds perfect to me. A photo tour of Montmartre would be wonderful. So, that's on my 'to do' list too.
There are still many museums we haven't seen; the Architecture Museum (I read that the cafe has a fabulous view of the Eiffel Tower) and the Counterfeit Museum are on the top of the list. Of course, we will go to the Louvre again. It's so big that there is always something new to discover.
There 2 areas of Paris that have also been on the list for several years~ Buttes aux Cailles and Canal St-Martin. Check the link~I have mentioned the Canal St-Martin before. It runs from the Bastille northeast to the Parc de Villette and is supposed to be a beautiful quiet walk.
Located on a hill, Buttes aux Cailles is a lesser known neighborhood in the 13th arr. It has a village-like atmosphere with winding, narrow cobblestone streets.
