Pick how long you have. Every plan is a fixed, curated route through Paris — the places worth your time, what they mean, the small rules locals follow, and one useful phrase a day.
Spring and September are best
Mid — cafes cost more at a table
The islands where the city began
Easy
Add the Louvre, gardens and covered passages
Comfortable
Montmartre mornings and village Paris
Steady
Arrondissement by arrondissement, plus Versailles
Slow, local
