If you like geology and rocks, this is the museum to visit in Paris. The entrance fees for students were a mere 6 Euros, and it gives you access to a stunning collection of gems, rocks and minerals. The staff that works here is exceptional and very informative. A bit of a trek to find, given its located deep within the Engineering building, but totally worth it. The building itself is beautifully maintained, reminded me of McGill, back home. I'm not a big rock lover, and I still managed to have a good time!
