How to go up the Montmartre Hill if funicular out of order ?

How to go up the Montmartre Hill  when the funicular is out of order can become a challenge for tourists and inhabitants of the district. This happens very rarely and there are 3 solutions that avoid that the top of Montmartre is isolated from the rest of the world! For information, except for normal maintenance, the funicular was interrupted between 1932 and 1935 and also between late 2006 and June 2007.
Going up the Montmartre Hill by the stairs to the Sacré-Coeur : a sportive climb
The main and direct staircase is the one along the funicular. The entrance of the stairs is at 1 Place Valadon (which is in fact a street, not a square). It is located at the junction between the street Tardieu and the street Saint Pierre (called "Place Saint Pierre"!?). The "Place Valadon" turns into a staircase 30 m further on, which is called "rue Foyatier"! Who knows why "rue" instead of "escalier" ? This staircase which goes along the funicular (the "Foyatier street") has two hundred and twenty two steps. It leads to the upper station of the funicular at the junction of rue Saint Eleuthère and rue du Cardinal Dubois - which you cross to reach the stairs in front of you that you climb to rue Azaïs that you take on the right. The Parvis and the Basilica du Sacré-Coeur  are 50 m away. If during your ascent you did not take the time to admire the panorama it is now of the Parvis that you have the best sight on Paris.
The 38 stairs of the Montmartre Hill
It is also possible to go up to the Sacré-Coeur by several stairs located in the Square Louise Michel, on the right of the funicular.
There are also many other staircases to go up the Butte Montmartre or down it from the north or west sides. It seems that there are 38 stairs. You will certainly have the opportunity to take some. We have listed some of them below:

Staircase Paul Albert, "Littérateur"
Stairs of the street Utrillo
Passage Cottin
Staircase of the rue du Chevalier de la Barre : It leads to the garden of Turlure, close to the Sacré-Cœur. You have to come at night to look at its cobblestones that turn into a starry sky. It is Alekan, chief operator and the sculptor Patrick Rimoux, who reproduced with optical fibers, the constellations of January 1st and July 1st.
Going down rue Lamarck, you come across the stairs of rue Becquerel.
On the other side of rue Lamarck, a pétanque court that is always frequented and another staircase, rue de la Bonne: there was one of the fountains of Montmartre whose water was famous.
A little further down, the stairs of the rue du Mont-Cenis. One of the longest of the Butte. It is more oriented to the north than to the east

It is these stairs that make Montmartre "feel" like a hill and that you need to have strong legs to "navigate" on the Butte. Indeed no private vehicles are allowed, except for light service vehicles (deliveries). However, some poets have sung about them ("They are hard on the wretched...")!

The RATP bus, line n° 40 (Mairie du 18e - Jules Joffrin to Le Peletier stops)
This is the only RATP bus line to go up the Montmartre Hill and travel on the Butte Montmartre. It is a bus reduced in length to take the narrow streets of the Butte. It is a circular bus and has no end: the starting point is the Pelletier station located at the bottom of the Butte, on the south side (Pigalle) and the northernmost stop is the Mairie du 18e - Jules Joffrin metro station. The Bus 40 returns to its starting point after a 4 km ride that takes it to the other side of the Butte, on the north side, through the streets at the top of the Butte, after 35 intermediate stops and in 25 to 35 minutes.
The itinerary to climb the Butte Montmartre overlaps in some points with the return itinerary, which adds to the confusion and does not facilitate the comprehension of the route in its median part. You will find opposite the map of the line 40, the stops, the connections with the metro or other buses and the direction of passage of the bus at each stop (arrow).
The bus of the line 40 operates from Monday to Saturday from 7:30 am (time at the point of departure of the line) to 1:10 am approximately and Sundays and holidays from 7:20 am. Its frequency is :

A bus every 10 to 30 minutes on weekdays (10 to 15 minutes during the day)
One bus every 11 to 25 minutes on Saturdays
One bus every 12 to 25 minutes on Sundays
