Description of the walk

Departure from the car park, free (530 spaces), Le Galiote de Mers-les-Bains.

(S/E) Exit on the left via Rue du 4 Septembre to reach Rue des Canadiens, then turn left. Turn right onto Rue du 19 Mars 1962.

(1) Cross Avenue du 18 Juin 1940. Opposite, take Rue Sadi Carnot. Turn right onto Esplanade du Général Leclerc and continue for 400 m. Cross Rue Jules Barni on the right.

(2) Take Ruelle des Matelots to climb Chemin de l'Église. Climb the last steps on the left, which lead to Rue Joseph Legad, which continues into Rue de la Falaise.

(3) Follow the path on the left, before the car park, to climb up to the Notre-Dame-de-la-Falaise monument. Continue along the coast on the coastal path, keeping away from the edge of the cliff (as it is unstable).

(4) Yellow markings help hikers for about 3,000 metres.

(5) Walk along the Bois de Rompval and arrive at the Bois de Cise.

(6) Cross the fence and turn right onto Chemin du Grand Mont for 160 m.

(7) Turn left onto Allée du Muguet.
Then:
- either continue straight down Allée du Muguet (or the steps).
- or take the road on the left, Route de la Falaise, which winds down to a roundabout (see description).

(8) Go up Grande Rue du Bois de Cise on the right, which continues as Route du Vieux Chêne for 1,100 m.

(9) At the exit of Bois de Cise, turn right onto the path (just before the rubbish bins). Continue straight ahead on the tarmac path until you reach Le Rompval campsite.

(10) Take Rue André Dumont, then join the tarmac road for 900 m until you reach a multiple junction and a stop sign at the Mer les Bains town sign.

(11) Cross the road and take the path opposite for 100 m, then turn right. Go down Chemin des Valines, which winds its way before coming out onto Rue André Dumont.

(12) At the roundabout, continue straight ahead and descend for 600 m until you reach the stop sign. Turn left onto Rue Lucien Leduc, then right after 40 m.

(13) Turn left onto Rue Charlemagne to reach Rue du 4 Septembre. Turn left and continue for about 60 metres until you reach the Le Galiote car park on your right (S/E).

If you want to follow the coast, this is the way to go. We preferred to do a return trip rather than a circular route.

A very pleasant walk along the coast and cliffs on the way there, and through the countryside on the way back! A lovely discovery of the village of Bois de Cise in the middle! Staying on the seafront, we headed straight for the cliffs without going through the streets of Mers.

A very pleasant route, with the first part along the cliff top offering magnificent views. The second part is through the countryside on a cycle path.

Be careful on the cliff, as the route changes when the cliff collapses and the path changes

I like it when the paths are marked from the wood after the rubbish bins, with no more signs or street names.

A very pleasant walk with magnificent views.
Just to clarify, at point number 1, you need to cross Avenue du 18 Juin 1940 or Avenue du Maréchal Foch.
We couldn't find point number 11, so we continued down Rue André Dumont along the cycle path.

A very beautiful and fairly easy hike, there are even detours to avoid the steepest slopes when walking along the cliff. Good to know: when we arrived at Allée du Muguet, we were suddenly caught in a heavy storm. Fortunately, we were able to take shelter immediately below the Grande Rue du Bois de Cise, where there is also a crêpe vendor and toilets. The shelter was large enough to accommodate all the hikers that day. On our way back to Mers, we didn't see the sign for Rue André Dumont at first, but with the description, it wasn't a problem.

A wonderful discovery of the site between Mers-les-Bains and Bois de Cise, as well as the villas of Bois de Cise.
