Car park at the Complexe Sportif des Trois Chênes, situated on the Plateau de l’Espace.
(S/E) From the car park, look up and you’ll see a mobile phone mast: you need to walk past the base of this mast (which will then be on your left), then continue along the main path which curves to the right. From there, you can see the facilities of the Equestrian Centre (on your right).
(1) Take the Route François 1er and carry on straight ahead, crossing the street called “Allée des Stands”.
(2) Turn left onto thefirst path and carry on to the end.
(3) Head down Route des Cascades on the right; this is usually closed to vehicles on Sundays but accessible to pedestrians. Continue to the hamlet of Fontaine de Tilly, which is full of points of interest.
Take the time to look out for an old fountain once used by the Duke of Pentièvre, a ‘pyramid’ commissioned by the Duchess of Orléans (wife of Louis Philippe, King of France), a wooden cross bearing the name of the place, and a stone commemorating the sacrifice of British soldiers for the country’s liberation.
(4) Please note: do not walk along the D181. To find your way, look for an old track situated between the path you should take and the D181.
Without joining the D181, take this path on the left, which runs alongside the D181 before veering off to the left to reach a crossroads.
(5) Turn onto the path on the right to head down the Côte du Mont Roberge: to help you find your way, there is a sign created by children from a nursery school at this junction. Continue to Vernonnet.
(6) Continue left along the Route du Docteur Chanoine and admire the stone houses of Vernon.
(7) Pass in front of Saint-Nicolas Church: on its right-hand side, you can see the old door from the original church. Continue straight on along the D313.
(8) Turn left up the Route aux Potiers, ignoring the old ‘Military Land’ signs: this is in fact a public national forest. Join a path crossing the Côte du Roule, turn right and reach a tarmac road after passing an old quarry on your left. Turn left onto the Route de la Queue d’Haye, passing the entrance to the quarry, which is still in operation by the company TERH: be careful on weekdays, as you may encounter large construction vehicles.
(9) Leave the road and take a path on the left which rejoins the road further on; continue straight ahead.
(10) Finally, turn left onto the unnamed track, which runs alongside the former LRBA site, until you return to the car park (S/E).
