(S/E) Head towards the Loire, then turn left upstream along the Loire and follow Quai Henri Brunais to the right for 400 m.
(1) At the bend, turn right towards the footbridge. Turn left, then, a little further on, right to reach the roundabout; go round it on the left to join Rue Danielle Mitterand.
(2) Veer slightly to the left below the road, then head north. Go through the tunnel under the road and follow the path to your right, then to your left for about twenty metres. Walk straight up the small Colline de Tougas.
(3) You are now at the highest point of the hill, with a field of solar panels on your right. Walk down the hill towards the north, following the zigzagging path. At the bottom of the descent, turn right and walk alongside the railway line for 700 m.

(6) Retrace your steps, then turn left onto the small path, and turn right to take the path that leads down to Boulevard Charles de Gaulle.
(7) Go through the tunnel that runs underneath it and, at the junction of the paths, carry on straight ahead towards the north. Ignore the paths on the left and follow the same path, which curves slightly to the left towards a housing estate.
(8) Go round the estate on the left until you reach the roundabout on Boulevard Charles de Gaulle.
(9) At the roundabout, head left onto Rue du Rocher and, almost immediately, turn left onto the path leading to Rue Eugénie Cotton; follow this to the right, then continue straight ahead on the path in front of you, which rejoins the end of Rue Eugénie Cotton.
(10) Take the path on your left and turn right. At the next junction, turn right, then left. Continue along the path overlooking the lake until you reach the fork from the outward journey.
(5) Retrace your steps along the outward route until you reach the railway line.
(4) As you emerge from the railway tunnel, turn right onto the path that skirts Tougas Hill on the right; go through the tunnel on the right to reach point 2.
(2) Turn right, then continue straight on along a footpath heading south. At the end, turn right, cross Avenue de la Loire straight ahead, then turn left onto Rue Elsa Triolet, then turn right towards Rue du Pont Allard. Follow this street to the right for 20 metres.
(11) Turn left onto Rue du Calvaire, which climbs steeply and then bends to the right.
