GR®®34markings: White and red
(S/E) Cross the boulevard, take the Jean Marin footbridge opposite to cross the floating dock, then climb the stairs on the right. Follow the wooded path overlooking the sea to reach the marina.
(1) Go around the basins along the quays and follow the Quai de l'Yser (East) on the right. Continue along Rue du Môle, which runs alongside the inlet leading to the marina. On the opposite bank (on your right), you will see Île Tristan and, on your left, the new nautical centre at the foot of the cliff.
(2) Leave theGR®® for a moment to go down to the pier, which ends with a lighthouse marking the entrance to the Port of Tréboul, then take the stairs back to the coastal path. Follow it to the right, passing below the marine cemetery.
(3) Pass the small Saint-Jean beach and climb up to the chapel of the same name. Go around the chapel on the right (look for a double bust of Max Jacob on the left) and continue along the Passage de l'Armen.
At the grassy esplanade, make a small detour to the left to see the monument in memory of sailors lost at sea, then rejoin the coastal path on the right and continue westwards. Descend towards Plage des Sables Blancs beach via the path that makes a small circular loop (marked route). There is also a steeper staircase.
(4) Walk along Plage des Sables Blancs either on the sand or on the promenade (marked on the map) which runs alongside and around the beach. Turn right towards the water sports centre, noting a small menhir near the car park as you pass, then continue along the pier by the sea until you reach a double staircase.
(5) Go up these steps and turn right at the road. Pass a holiday centre, turn right (marking on the wall), cross a car park and you will reach the coastal path, which you will follow to the left, heading west. You will reach the bottom of the protected area of Vallon Saint-Pierre, which can be identified by the small stream that flows into it.
No markings
(6) Leave theGR®® trail, which continues to the right, heading north-west, and climb up to the left along the small path that crosses and then runs alongside a stream. Be careful, as some of the stones may be slippery. At the first fork, continue to the right and climb to the top of the valley (information board). Turn right towards the fountain.
(7) Join the road. Follow this coastal road to the left, which descends towards the beach.
Pass the first street on the right, Rue Ménez Poazh, which climbs up to a housing estate, and take a path on the right that joins this street. Pass the first cul-de-sac on the right and continue. At the top, turn left (campsite opposite) and continue straight on along Avenue du Bois d'Isis, which narrows (alternating traffic) and begins a beautiful descent offering a view of the sea.
Pass Rue du Coteau, which joins on the left, and continue along the same street.
It runs alongside old houses built on the heights of Bois d'Ys, where there is also a campsite.
When you reach a no entry sign at Rue Prad al Lin (signposted town centre), continue to the end of Avenue du Bois d'Isis. Turn left into the no entry street just before a dead end sign. Go down it, cross Rue des Sables Blancs at the pedestrian crossing and continue opposite in Passage des Lavandières. Look out for an old wash house on the right, which is unfortunately abandoned, then go up a path towards Rue Fernand Le Goïc.
(8) Go down it on the right, then take Rue Jakez Riou on the left for about ten metres. Turn right, cross a small car park and go up a grassy area to reach a dead end, then Rue Fernard Le Goïc, which leads to Rue des Professeurs Curie on the right.
(9) Leave Rue du Rheun opposite and take Passage des Sirènes on the right, which leads to a street where there is a small calvary topped with an iron cross (look for a skull sculpture on the north side). Continue along Rue du Maréchal Foch, which descends, and arrive at a grassy area with children's playground equipment.
(10) Turn left and walk up this field to reach the marine cemetery (Rue Henri Cheffer), then turn right to go around the cemetery: there is a viewpoint overlooking the cemetery, which dominates Douarnenez Bay. Continue down the street and at the three-way junction, turn right into the street that leads to the church, then turn right to go around it. In Rue des FFI, turn left then right and you will come out opposite the presbytery (no. 4). Pass by a transformer and toilets and take a small staircase down to an alley called Rue Gabriel Castrec. Turn left into this alley and at the end turn right.
(11) Take Rue d'Ys (narrow alley). Be careful, this alley is so narrow that you can pass it without seeing it. Do not continue down towards the port. At the end of the alley, turn right and then immediately left to continue along Rue Tourville (flower-lined alley). Make a slight left/right turn and continue straight ahead. At the end of this street (L'Esquisse restaurant), turn right onto Rue Jeanne D'Arc. Go through a wooden gate and walk up this small, steep street (a handrail can help you).
When you reach a small square, turn left into Venelle Poulmerrien. Follow this narrow passageway, which turns sharply left and leads to Rue du Moulin. Turn right into this uphill street lined with grassy land.
At thethree-way junction, continue straight ahead along Rue de la Montagne to go around the hill where the old windmill, now converted into a house, is located, then turn left to go back down Rue du Moulin.
Turn right onto this grassy area dotted with small granite boulders (viewpoint over the port of Tréboul). Descend via a dirt track secured by two metal railings and finish with a staircase at the post office.
Cross the street at the pedestrian crossings, go around the small market building on the left and cross this large square diagonally.
(13) Go around the shipyard on the right and take the steps at the back of the shipyard, which lead to Rue Pen ar Vir. Follow it to the right, go down to the left into Rue Anne de Bretagne, then left again into Rue du Treiz, which leads to the edge of the Port Rhu basin.
(14) Turn left to walk along the basin, cross the footbridge again and return to the car park (S/E).
before leaving the GR, avoid crossing the small stream.... Take a small path on the left, which is easier
