It's free in Paris and it's rare. Let's take advantage of it!
In Paris and Ile-de-France, the free museums are more numerous than one would think. Sometimes, free of charge only for young people (children, teenagers, students and young adults up to 26 years old). In other cases, some museums are free on the 1st Sunday of the month or a day of the week. A number of Parisian museums offer access to free to all of their permanent collection. Finally, some museums are simply free, always and for all, but be aware that on free days, there may be a few more people than usual. If your goal is to visit a museum with few people, prefer the days of night in the museums.
