Start from Plage du Béchet, a stone's throw from the village of Saint-Briac-sur-Mer.
(S/E) Go down to the beach and walk along it to the left until you reach the steps leading up the cliff. These lead to the mini golf course, which you follow to reach the boulevard with the beautiful name of Balcon d'Émeraude, just above the last stretch of the Frémur.
When the cliff recedes from the road to make way for a sort of park at the foot of the suspended villas, cross the boulevard and take the steps that climb up the cliff to weave between a few buildings clinging to the edge of the void.
(1) Following this winding path, you will eventually come out onto Boulevard de la Mer (actually a quiet little street). Turn right to cross a neighbourhood of beautiful seaside villas, less ostentatious than those in Dinard but no less charming. You will reach the Croix des Marins, which offers a beautiful view of the Frémur estuary. Continue to the left along Rue de la Croix des Marins, walking up the row of austere granite houses that line this street.
Just before the crossroads at the end of this street, turn left up the alleyway that leads to the church.
(2) From the church, walk up to the small square where the post office and a pretty shop with remarkable mosaics are located. Walk up the street in front of it until you find Rue du Buot on your right.
(3) Take this street and continue straight ahead at the next three-way junction to go up Chemin des Tourelles. When you reach Rue des Hauts Champs, continue straight ahead and pass to the left of the nursing home. Leave the urban streets behind and take a small path under the trees, which you follow until you reach Rue des Belles Noës.
(4) Turn left and follow this country road until you reach Rue de la Ville aux Trigots. Please note that this road is narrow and has no shoulder, so take care when walking along it.
When you reach Rue de la Ville aux Trigots, turn left and then right at the next crossroads. You will then find yourself on a street lined with large, multi-storey farmhouses.
(5) Turn left, then right at the first street. This cul-de-sac is extended by a narrow path that leads to a cross street further on. Continue straight ahead to leave the urbanised areas behind, until you reach Rue de Mesnil. Turn right to reach the old centre of La Fosse, where you will find the typical farmhouses of the region.
(6) At the three-way junction, take the left branch and, once you have gone around the block, turn left onto Rue de Ker Gai. This small road covers the last few hundred metres before the coastal road. When you reach this road, cross over to the other side to take the access road to Longchamp Beach.
(7) The coastal path begins at the western end of the beach. It quickly takes on the rugged appearance of a customs officers' path in rocky areas. To reach the dome that forms Pointe de la Garde Guérin, follow the rugged, rocky coastline as closely as possible before turning around and climbing up the hill: there is a beautiful view of Saint-Malo and Cap Fréhel from this isolated hilltop. Continue downhill towards a series of small coves above which golfers play. Continue along the path until you reach the buildings of Port Hue.
(8) If the tide allows, turn right to go down to the beach and rejoin theGR® 34 at its other end. Otherwise, follow the markings on this path around this part of the Dinard golf course where there is no customs officers' path. When you rejoin the latter, follow it to the entrance to Pointe de la Haye. There is no point in venturing any further as the path is a dead end.
(9) After passing the golf course, you will reach a more challenging section of the route. After passing the access point to Petite Salinette Beach, you can walk along the sand to reach its eastern end, tide permitting. A staircase allows you to climb back up to the customs officers' path. Otherwise, turn left just before reaching the beach and continue winding your way along the path. There's no risk of getting lost, as you're well guided so as not to go beyond what is permitted.
As soon as you catch sight of Grande Salinette Beach, things improve and you'll soon find yourself on the sand of this pretty beach with its white cabins. Be careful of the strong tidal coefficients, which may require you to take off your shoes for a few metres when descending the steps leading down to the beach. As you leave the beach, leave the entrance to the imposing castle hotel that dominates the landscape on your right, and on the other side of the sandy isthmus, you will find the beautiful Plage du Béchet beach with its blue cabins (S/E).
