Access: Take the N165 between Nantes and Vannes. When leaving Muzillac, follow the D5 in the direction of Billiers.
There are many places to park in Billiers around the church. Toilets are available. You will follow a PR®, although its waymarking is difficult to find.
(S/E) Behind the church take Grande Rue towards Bréhondec. Follow along the tarmacked road until you reach a fork with a cross in the middle of it.
(1) Turn right and continue straight ahead on the dirt path. Cross through the area of warehouses and follow the tarmacked path on the right.
(2) Continue to the left on the seldom used tarmacked road. Go past the wastewater treatment plant on the right and then the hamlet of Kervail. 300m later, turn right and continue on to the fork with a cross.
(3) Follow the tarmacked path for about 500m and just before Le Bourg L’Étang, turn left onto the farm track until you reach the place called Guernehué.
(4) At the farm, turn left for 100m then right and continue through the pine forest until you reach the coastal path (GR® 34-39).
(5) Follow the coastal path up to Pointe de Penn Lann. Pass the Dolmen, the Crapaud (6) and then Grays Cairn (7).
(8) Go past the front of the hotel and re-join the coastal path so as to go around Pointe de Penn Lann, and then go past Billiers Port. The levy along from the Billiers seaside gîte is closed with barricades.
(9) Go over the barricades and follow along the levy. At the end of this first section, there is a slightly difficult section to cross further up from the seaside gite. Follow the path along the marshes and, at the junction with the D5, turn right to return to the church (S/E).
