GR®34 marked in white and red
(S/E) With your back to the car park, go around Port Blanc Beach and reach a panoramic viewpoint of Pointe Annalouesten: to the east is Pointe de Primel, which opens onto Morlaix Bay, and to the west is Roscoff and the Île de Batz, which closes it off.
(1) Continue on the GR®, heading south.
(2) At this point, note that the wall surrounding the house on the pebble beach has been almost completely destroyed by the pebbles during storms or when the tide is high. Continue to Guerzit Beach, go around it and reach Pointe de Perhérel and its viewpoint.
(3) Continue towards Saint-Samson Beach.
(4) Cross the beach and continue almost to the end to rejoin the GR® trail, avoiding the paved section (possible at low tide). Continue to the right and head for the Pierre Double viewpoint.
(5) Continue to follow the GR®, pass Pointe Saint-Samson and reach a charming little beach.
(6) Continue towards Térénez and rejoin the tarmac just before reaching the hamlet and its famous sailing school.
(7) Turn around and return along the same route to the car park at Port Blanc beach in Le Diben (S/E).
