Breathtaking view of the Seine

Highlight • Viewpoint

Here we enjoy an incredible view of the Seine and the bridge. Admire how the river, the greenery and the city come together.

The statue of Napoleon watches over the route of a hike called “In the footsteps of Napoleon”. It is a circuit located in Forges in Seine-et-Marne (77). It is partly juxtaposed with the GR 2, the Seine Trail.

March 31, 2024, Boucle à Montereau par la réserve des Seiglats

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)
