Departure from Annoville-Plage, at a place called Village de la Mer, just before the seafront. Park in the car park for access to the dunes, on the left-hand side of the road when heading towards the sea (gantry, hiking signposts).
Red and white markings
(S/E) Take theGR®223, which starts behind a barrier (signposted "Dunes d'Annoville"). Walk south with fenced meadows on your left. Cross a small car park and you will come to a tarmac road.
No markings
A few posts mark the path, at the top of which you will sometimes find the faded remains of yellow markings.
(1) Cross the road and continue straight ahead to reach a wide path (signposted "Dunes d'Annoville") which turns right and then left. Continue south and, when the path ends at a fence, turn right and head down towards the beach. At the bottom of the descent, turn left onto a sandy path (at low tide, you can also go straight to the beach and follow it on the left).
No markings
(2) Cross the Cale de Lingreville (concrete slope leading to the sea at the end of a road). Immediately climb up the dune on the left and follow a faint path (not shown on the map). Stay on top of the dune and, when the path ends at some fenced-off bushes, take a small wooden staircase on the right. Descend towards the beach, turn left and return to the top of the dune as soon as possible. Continue south.
(3) You will come to a sandy road (Rue des Verrouis on the map) and follow it to the left for a few metres. Just after passing a "No Traffic" sign on the left-hand side, turn right onto a wide path. At the corner of a pine grove, with a path coming from the left (marked "Circuit des Matelots"), turn right. At the top of the dune, turn left and follow a faint path southwards through the grass. Ignore several perpendicular paths and stay on high ground until you reach a fence with an isolated house on the left and the Havre de la Vanlée opposite.
(4) Walk along the fence, keeping it on your left, heading east. Go around a barrier on the right, descending slightly, and you will come out onto a wide path.
(5) Turn right and wade across the Havre de la Vanlée backwater.
N.B. The IGN map is not up to date here. The route has been mapped using satellite imagery.
Turn left and walk along the active branch of the harbour, located on your right. Shortly after passing a pipe, wade across the dead branch again. Immediately climb up to the top of the bank opposite, at a fence with a small wood on the left and a lawn on the right. Head towards a white gate and take a small road through a passage in the fence to the right of the gate.
Yellow markings
(6) Follow the small road to the right (east) for 500 metres.
Red and white markings
(7) At a bend in the road on the left, rejoin theGR®223and turn left onto a stony path (signposted "Chemin des Matelots"; ignore the signposted "Circuit des Matelots" which invites you to retrace your steps). After a few zigzags, at the corner of a fire hydrant, turn left onto a wide, shaded path.
(8) Take the first path on the right and walk along a stream on your left. Continue straight ahead (north), crossing two roads in succession (EDF power station at the second).
(9) At the next crossroads, at a place called Les Mielles, turn left onto a path separated from the road on your right by a wide verge. Further on, follow the road straight ahead to reach the car park you crossed on the way there.
(1) Turn right, cross the car park and follow the path you took on the way there northwards to return to the starting point (S/E).
Departure from the Garennes campsite = 11.90 km and 2 hours 25 minutes.
