Information about the 49km long Canal du Loing

Loing location France Map

The Canal du Loing, one of the series of waterways forming the ‘Bourbonnais’ route from Paris to Lyon, connects with the Canal de Briare below Buges lock, north of Montargis, and runs down the Loing valley (using the bed of the river at two places) to enter the Seine at Saint-Mammès, a distance of 49km.Loing location France Region Map

History – With the canals from Briare and Orléans completed respectively in 1641 and 1693, merchants started complaining about the poor navigability of the river Loing. The Duc d’Orléans ordered a survey and designs for the navigation as built – part-river and part-canal – were submitted to Royal assent and approved in 1720. Work started immediately, and the canal was completed in 1723, with some improvements made the following year. The first lock, Cepoy, dates from 1680 since it was part of the Canal d’Orléans. Modernisation to Freycinet dimensions was completed in the late 19th century.


Key Waterway Dimensions

  • Max Beam: 5.20m
  • Max Height: 3.50m
  • Max Draught: 1.80m


Locks – There are 18 locks, with uniform dimensions of 39.10 by 5.20m, plus a flood lock at Fromonville (No 13), which is normally open. The original lock 20 at Saint-Mammès was taken out of service and the adjacent weir demolished when Champagne weir and locks were built on the Upper Seine.

Draught – The maximum authorised draught is 1.80m.

Headroom – All bridges leave a minimum headroom of 3.50m above the normal water level.

Towpath – There is a good towpath throughout, with the exception of the sections through Montargis, Nemours and Saint-Mammès.

Traffic – This canal still carries some freight as the main route south from the Seine basin to the Saône. Traffic has declined, but the canal remains open all year round to accommodate commercial barges moving to and from the Saône.
