Park in the car park at the top of the village in front of the Maginot Line fort, at Square Sainte-Agnès.
(S/E) This hike begins with a visit to the highest point of the village. There is an information map of the site in the car park. Take the staircase called Montée du Souvenir, towards the cemetery, which leads, after some 200 steps, to the ruins of the 12th-century castle. This castle overlooks Sainte-Agnès and offers a magnificent 360° panorama. After consulting the orientation tables, turn around and return to the starting point.
(S/E) Turn right at the bottom of the steps and walk down the beautiful old Rue des Sarrazins, which is the main street in Sainte-Agnès. Walk past the church and town hall, then take Rue du Four and Rue des Comtes de Léotardi towards Avenue de Verdun. At this point, first turn right then left and take the paved slanting street called Promenade Saint-Sébastien, which leads down to the chapel of the same name. Continue to marker 440.
(1) Turn right onto theGR®51, towards Castellar - La Virette, and walk alongside the water treatment plant. This beautiful path becomes a paved slanting street a few hundred metres further on. You will reach the ruins of the hamlet of La Virette.
(2) Turn right between the two ruined houses (marker 476). Follow this unmarked, wooded path downhill, winding in short loops towards the south.
(3) At this point, you will come to a clearing. The path arrives at a small cirque where the Borrigo waterfall flows, and a stop at this site is a must. Continue on the path that starts on the south side of this cirque with a cairn. Continue on this path lined with tall vegetation, which turns into a carriage road after 200 m. Go through the forest gate and continue on an asphalted section. Reach a road junction (unmarked on the ground - number 490 on the map).
(4) Turn right onto Chemin du Vivaron. Pass marker 489 and continue along the asphalt road until the next bend. At this point, go straight ahead onto a path lined with properties.
(5) Walk along the back of a house, then turn right for about 30 metres, then go up the tarmac road on the left to marker 463.
(6) Turn right and follow the signs for "Village de Sainte-Agnès". From this point, the path climbs to the end point. There are magnificent views of Menton and the coastline throughout. Marker 462 is missing; ignore any trail junctions and continue straight ahead to reach the end of the trail, which is located below the terrace of the panoramic restaurant.
(7) In the last few metres, it is tempting to choose another route. Continue towards the restaurant where marker 461 is located. A glance down below reveals the path at the bottom that you took during this beautiful climb. A few metres further on is the car park (S/E).
