The heart of the route fits into six kilometres, with the links to and from the meeting point on top, so about thirteen kilometres in all. Those six kilometres hold the Île Saint-Louis, the Montagne Sainte-Geneviève, the rue Mouffetard, the Luxembourg gardens and Saint-Germain-des-Prés. On foot you cover a third of it in an afternoon. On an electric bike you link the whole thing, without sweating up the hill to the Panthéon, and there is still time to stand in front of the doorways. Seven stops, one guide, and buildings that turn back into addresses: where someone sculpted for fourteen years before being confined for thirty, where someone wrote because there was no heating at home, where a street still carries the name of a theatre that left in 1770.
The writers of Paris left few plaques and a great many stories. Camille Claudel lived and sculpted on the quai de Bourbon from 1899 until she was committed, in March 1913. Voltaire and Rousseau, who cordially loathed one another, now lie face to face in the Panthéon crypt, which you only see if you go inside and which the price does not cover. Descartes came back to Saint-Germain-des-Prés in 1819, without his skull, which went astray on the way. Hemingway wrote his first Paris pages a hundred metres from the rue Mouffetard, in two rooms with no hot water. These are the stories we go looking for, façade after façade, from the pavement and from the square.
The tour can be booked as a shared ride, where you join a small group, or as a private ride for your party alone. Indicative prices, all taxes included: on a shared ride, 75 euros per person; private, 95 euros per person. It is never a group package. The electric bike and the helmet are included. The final price, the date and the meeting point are confirmed to you in writing before any payment, and your request is not yet a firm booking. Each group takes five participants at most per guide; beyond five participants we may be able to run a second group at the same time, subject to availability, at the same price per person, and we confirm that to you in writing. A break is planned halfway round: we have no agreement with any establishment, we book no table and we negotiate no rate; anything you order is at your own expense and nothing of the kind is included in the price. The tour starts in the 7th arrondissement and comes back to it.
No entrance fees, no interiors and nothing to eat or drink are included in the price. The Panthéon, the church of Saint-Germain-des-Prés and Delacroix's studio are told from the square or from the forecourt; the guide will tell you which ones are worth coming back to on foot, and in what order.
