The march covers a part of the 10th and 18th arrondissements and lasts some four or five hours. Starting point is close to the Ganesh Temple, at the metro station, Chapelle. I took the photos at the upper parts of Rue du Faubourg Saint-Denis, today completely occupied by Indian, Pakistani and Sri Lankan shops and restaurants. This is where all the participants gathered and prepared themselves for the march. (See map at the end of the post.)
There are a lot of coconuts around. Breaking and crushing coconuts is an important part of the Hindu ritual. You will have to look for the symbolism of this elsewhere.
At last, some shots of the people in and around the procession.
