hi, easiest way go to Pont Saint-Michel metro station, in here you found the notre dame, this are most beutiful. after to south 15 minute walk to phanteon turn west to Le Jardin du Luxembourg other 10 minutes walk.
40 minutes walk to Hôtel des Invalides same direction, first time little long, but you see paris stile and feeling everywhere, after this more 20 minutes to eiffel tower is so amazing.
not to popular, but i like it the Pont de Bir Hakeim bridge from here 12 minutes walk (many movies make in here).
other 40 minutes walk to Arc de Triomphe to north, but across this way the Trocadéro Square so you not bored this. Arc de Triomphe careful, traffic is crazy and busy, search the underpass, hard to see but have. and from here turn back to original start to east you across the 1 hour just wak but you stap the Champs-Élysées, Pont Alexandre-III bridge ( this location and area have Petit Palais, the entrace is FREE) Place de la Concorde, Les Tuileries and the Louvre.
So you follow this little harcore legday line in a one day you say 70 % parts of paris.
i hope i help,
