Park on Quai Paul Signac.
(S/E) Follow the quay towards the village, with the Seine on your left. Turn right onto Rue Bellevue and continue until you reach Rue Grande. Turn left onto this street and pass the Saint-Sauveur Church on your right. Continue along Rue Saint-Jacques until you reach Rue Georges Guynemer (D313). Turn right onto this street.
(1) 100 metres further on, on a wide grassy pavement, look for a small yellow sign on the left indicating "Val Saint Martin 4.5km". This is the starting point of the narrow path that climbs steeply. There is also red and white signage as this is theGR®2.
Instructions for the entire upper part of this circuit (unless otherwise indicated in the description below):
- Follow the red and white markings for theGR®2.
- Until you reach Val Saint-Martin, never take a path that branches off to the right.
(2) To illustrate this instruction, when you reach the top of this first climb, keep left and do not take the path that branches off to the right. Continue in this direction until you reach the descent to the small tarmac road (Chemin de la Fontaine), which you should take on the left towards Val Saint-Martin.
(3) At the end of this small road, turn right onto Route des Andelys and continue onto Côte du Thuit.
(4) After about 100 metres, take the path that climbs up to the left. At the top of the first section of the path, it crosses a road. Cross and continue along the path on the other side of the road. After about 500 metres of climbing, the path meets another road (actually the same one). Cross it and continue straight ahead along the wide grassy path, keeping the road on your right. At the end, the path turns at a right angle and runs alongside the wall of the Château du Thuit. Follow this wall until you reach the road (D126).
(5) At the end of the wall, follow the road on your left towards the village of Le Thuit. You will pass the castle where Georges Guynemer, one of the pioneers of aviation, lived.
(6) Just before the town hall and church, turn left onto Rue de l'Église and follow it until Rue des Falaises.
(7) At the old bucket pump at the corner of the pond, turn left onto Rue des Falaises, which turns right 100 metres further on. Leave this road and take the path opposite, which descends through the woods. When you reach Roche Percée, the path zigzags a few times. Follow theGR® markings carefully.
At one point during the descent, a sign indicates "La Spéléologue" to the left. Do not take this path and continue downhill until the narrow path opens onto a wider area with a wider path that branches off to the far left, from where you can see houses below.
(8) Leave theGR® and take the wider path on the far left. This descends and leads through a small tunnel to the road that runs alongside the Seine.
(9) Turn left onto the road that leads back to Les Andelys. This is the least pleasant part of the hike, as you have to walk along the road for about 1.8 km.
(10) At Val Saint-Martin, after passing the marina on your right, leave the road and take the path on the right, opposite the entrance to the hotel-restaurant, and head towards the banks of the Seine.
From there, it's plain sailing. Simply follow the Seine and enjoy the scenery until you reach the car park where you started (S/E).
