Loing River and Canal

The River Loing, a tributary of the Seine, is a vital and scenic waterway in central France. Spanning 143 kilometers, it flows through the Yonne, Loiret, and Seine-et-Marne departments, weaving its way through picturesque landscapes and historic towns. With a rich history as both a trade route and a source of natural beauty, the Loing remains an enduring symbol of the region's heritage.
A Scenic Journey
The river originates in Treigny-Perreuse-Sainte-Colombe and meanders through lush regions like the Puisaye and Gâtinais, often referred to as the "backbone" of the latter. Along its course, the Loing passes through charming towns:
- Saint-Fargeau, with its grand château and rich historical significance.
- Montargis, known as the "Venice of the Gâtinais" for its network of canals and delightful market atmosphere.
- Nemours, home to a stunning medieval castle.
- Moret-Loing-et-Orvanne, where the Loing meets the Seine in a setting beloved by Impressionist painters.
Interestingly, some geologists theorize that the Loing might have once been part of the Loire River, hinting at the region's ancient geological shifts.
Historical Importance
For centuries, the Loing was a bustling commercial waterway. Boats transported goods such as textiles, wine, vinegar, and timber, fueling the local economy. The river sustained entire communities of boatmen, merchants, and laborers. However, its unpredictable flow often made navigation treacherous.
To address these challenges, the Loing Canal was constructed in the early 18th century. Approved by King Louis XV in 1719 and completed in 1724, this 50-kilometer canal linked the Loing to the Briare and Orléans canals, creating an efficient trade route to the Seine and Paris. With 19 locks managing a descent of 35 meters, the canal was a feat of engineering that reduced navigation risks and boosted regional commerce.
From Commerce to Leisure
While the canal once bustled with trade, its role has shifted over time. Today, commercial traffic has largely given way to tourism. The old towpaths, once used by horses and people to pull barges, have become tranquil trails for walking and cycling. These scenic paths are part of the EuroVelo 3, a long-distance cycling route stretching across Europe from Norway to Spain.
The canal's peaceful waters now attract leisure boats, offering visitors a unique perspective on the countryside. Along the way, remnants of the canal's history, such as the house of canals in Nemours, highlight its former administrative and operational importance.
Water for Paris
Beyond navigation, the Loing plays a critical role in providing drinking water to Paris. The Loing and Lunain aqueduct, built in the early 20th century, channels water from the Loing's tributaries to the capital. Together with the older Vanne aqueduct, this system supplies an average of 51,000 cubic meters of water daily, showcasing the Loing's enduring utility.
