Park on Place d’Orléans or Place Saint-Laurent O’Toole.
(S/E) Set off from the town’s tourist office on Place Guillaume le Conquérant. On your left, the Collegiate Church of Notre-Dame and Saint-Laurent O’Toole is well worth a visit before you start your short walk. Cross the square and head down Rue du Collège between the Crédit Agricole bank and the DVM shop.
(1) After 250m, you’ll reach the Chapelle du Collège (do visit this remarkable building). Walk down Rue du Collège, which continues as Rue Octave Leconte, cross Rue de la République and take Rue Pasteur opposite (slightly to the right). Take the first street on the left, Rue des Déportés, veer slightly to the right to reach a junction with four traffic lights. Turn onto Boulevard Gambetta, then after about a hundred metres, at a fork, take Rue Sœur Sainte-Fideline slightly to the right.
(2) Turn right onto Chemin des Étangs, cross the level crossing and continue along the quiet road (Chemin or Rue de l’Isle). You will follow the River Bresle, then, as you pass a large meadow on your left, the Île-Bataille site; next, cross the “Bois sous la ville”, a ZNIEFF (Natural Area of Ecological, Faunistic and Floristic Interest), before passing a long industrial building in the commune of Ponts-et-Marais.
(3) At the end of Rue de l'Isle, turn left into Rue Robert Legout and Kléber Lesage, cross the Bresle, then reach the D1015.
(4) Cross the D1015 (take great care), take the Chemin de Jérusalem opposite (PR® signposted). This path winds its way uphill, crosses the Eu-Abbeville railway line, then climbs steeply up the Jérusalem hillside. Cross a wood before reaching the plateau of La Croix au Bailly: you have climbed 100 metres. Note on the right four German bunkers which allowed Third Reich forces to monitor the trajectory of V1 rockets fired from inland towards the United Kingdom. Continue to Gros Jacques.
(5) At Gros Jacques, turn left without crossing the D925, pass a silo on your right and head straight on along the tarmac road to Touvent (very little traffic). Follow this road for about 1.5 km, passing the Touvent farm (on your left) on the plateau.
(6) At the first fork, turn left onto Chemin de Saint-Laurent, which leads to the chapel of the same name.
.
(7) Saint-Laurent O’Toole Chapel, magnificent panoramic view over the entire Bresle valley (from the estuary and the port of Le Tréport, right inland). Head down a steep path to Place Albert Ier (initially follow thePR® signs). Starting as a simple path through pastures, it winds its way through a residential area. Do not follow the yellow signposting until the end of the route, which turns left and leads to Place Albert Ier.
(8) Once you reach Place Albert Ier, take the Chaussée de Picardie straight ahead and, at the first set of traffic lights, turn right onto Rue Lavoisier. Walk 100m, turn sharply left onto Rue Digue Catrix and cross a level crossing. Just before the bridge over the Bresle, turn right onto a path running alongside some modern buildings, then left to cross the Bresle. Immediately on the right, take Boulevard Hélène to its end (small public garden on your right).
(9) At the end of the boulevard, turn right, passing a public fountain and the old Packam mills. Take Rue de l’Abbé Cochet, which runs alongside the outbuildings and then the walls of Château d’Eu (currently under renovation; you may be diverted via a path closer to the old course of the River Bresle), then continue along Rue du Comte Henri Ier to the entrance of the campsite.
(10) Turn left at a 120° angle onto a dirt track; after 150m, you will see Château d’Eu ahead of you. Take the wide grassy avenue, then slightly to the right, a path leading to a gate (on the right, the restaurant Le Bragance, the château’s former ice house). On the left, go through the gate which leads you into the château’s French garden.
(11) Château d'Eu (visit this beautiful Renaissance building and the Louis-Philippe Museum). Walking around the museum via the Allée du Cheval, you will find yourself on the Place d'Orléans. (S/E).
