This route was planned by komoot.
While specific parking locations are not detailed, the trail is situated near Montereau-Fault-Yonne. It is advisable to look for public parking within or on the outskirts of the town, which would provide convenient access to the trailheads along the riverbanks.
The trail is generally considered dog-friendly. However, as parts of the route may pass through natural areas or near livestock, it's always best to keep dogs on a leash and ensure you clean up after them. Check for any local signage regarding specific restrictions.
The trail can be enjoyed year-round, but spring and autumn offer particularly pleasant conditions with mild temperatures and beautiful scenery. Summer can be warm, so an early start is recommended. Winter hiking is possible, but be prepared for potentially muddy sections and shorter daylight hours.
No, there are no specific permits or entrance fees required to hike the Loop at the confluence of the Seine and L'Yonne. The trail passes through the general area of the Réserve Naturelle des Seiglats, but access to the trail itself is free.
The loop is classified as 'moderate' and requires a good fitness level. With a minimal elevation gain of about 40 meters over 19.2 kilometers, it's manageable for most regular hikers. While sure-footedness is required (SAC 2-3), the paths are generally accessible, making it suitable for beginners with some hiking experience.
The estimated duration for completing the Loop at the confluence of the Seine and L'Yonne is approximately 4 hours and 52 minutes, or just under 5 hours. This estimate is for continuous hiking and does not include stops for breaks or sightseeing.
The trail offers picturesque views of the Seine and Yonne rivers, their confluence, and the surrounding greenery. You'll encounter riverbanks, meadows, and potentially charming village sections. The terrain is mostly accessible, likely a mix of paths suitable for hiking.
Key highlights include the unique experience of observing the confluence of the Yonne River and the Seine, offering a Breathtaking view of the Seine. You may also pass by a Bird sanctuary, providing opportunities for wildlife observation.
Yes, the route covers significant sections of 'La Boucle des Deux Fleuves' (70%) and also intersects with parts of 'de Montereau-Fault-Yonne à Sens (en projet)' (36%) and 'Véloroute La Seine à vélo (Tronçon Saint-Mammès - Crancey) projet' (24%).
The trail is located near Montereau-Fault-Yonne, a town with historical and architectural heritage. You can expect to find cafes, pubs, and public restrooms within the town, especially near the start or end points of the loop.
For this moderate hike, it's recommended to bring appropriate hiking shoes, sufficient water, snacks, sun protection (hat, sunscreen), and rain gear depending on the weather forecast. A map or GPS device is also advisable, though the trail is generally well-marked.
Well I admit it's not my best hike, I expected better in the Seiglats reserve... it must be said that the weather was not great at the end of the trip Be careful on the way out, taking the path along the Yonne, it is impassable, see the photos! Hopefully the trail will be maintained quickly, some trees have fallen. Forced to turn around and go through the main road for a good 20 minutes, not too many cars but be very careful! The other solution is to revisit the route and go to the other bank! IDF Mobility Access R line ROUND TRIP : - Gare de Lyon > Montereau (1 train per hour)
