Route Overview
The GR2 (Seine River Trail) runs in a point-to-point format from the official source of the Seine near Source-Seine in Burgundy to the river’s estuary at Le Havre on the English Channel.

The route passes through notable towns and cities such as Châtillon-sur-Seine, Troyes, Fontainebleau, Paris, Vernon, Rouen, and Le Havre.

Facilities such as water sources, restrooms, and accommodation options—ranging from hotels to campsites—are generally accessible in larger towns or close to major route segments. Trail markers are present, though navigational attention is needed, especially in rural or forested areas where signage can be faded. Advance planning is recommended for resupply points, especially outside major population centers, and for seasonal weather variations that can affect trail conditions.
Tracing Centuries: The Historical Legacy of the Seine River Trail
The Seine River has shaped the course of French history for millennia, serving as a vital waterway for trade, settlement, and culture since ancient times. Early Celtic and Gallo-Roman communities flourished along its banks, leaving behind remnants of fortifications, bridges, and waterways. Throughout the Middle Ages, the Seine’s shores hosted prosperous towns, majestic castles, and thriving monastic communities, many of which remain visible to hikers today through the abbeys and châteaux dotting the trail.
Paris, the centerpiece of the GR2 route, developed from a small island trading post in the Seine to become the political and cultural heart of France. The river played a crucial role during pivotal events such as the Viking incursions of the 9th century, medieval fairs, and the Renaissance expansion, as well as more recent history including the 19th-century Impressionist movement—artists like Monet and Renoir found endless inspiration along the Seine’s picturesque vistas.
The trail concludes in Normandy, where the Seine’s wide estuary has witnessed not only the rise and fall of ancient ports but also the devastation and liberation of World War II. From ancient relics to vibrant urban life and the scars of war still echoing on the landscape, walking the GR2 offers a living journey through the rich historical tapestry of northern France.

Challenges to expect
The GR2 (Seine River Trail) covers a substantial distance of approximately 850 kilometers, demanding sustained endurance and strong logistical planning. Multi-day sections require carrying gear or arranging accommodation in advance, especially in more remote rural stretches where facilities may be sparse.
Weather conditions throughout the hike can be variable, particularly in spring or autumn when rainfall is common and trails may become muddy and slippery. Riverbank paths can occasionally flood after heavy rain, posing detours or difficult walking conditions.
Navigation can present challenges, especially as the trail weaves through rural countryside, forests, and urban areas. While the trail is marked, some segments—particularly near agricultural fields or in wooded zones—may have faded signs or confusing junctions. Carrying updated maps, a GPS device, or a navigation app is recommended.
Long urban stretches, particularly through Paris, may involve crowded sidewalks, heavy traffic, and interruptions to the route, requiring extra vigilance and patience. Conversely, isolated rural stretches can feel lengthy and monotonous, with limited places to restock food or water. Proper preparation and strategic planning are key to overcoming these challenges.
