(S/E) We start from the landing stage where the shuttle boats from Roscoff dock, turning right after the "Les herbes folles" hotel.
(1) After 100 metres, take the path on the right towards the youth hostel, cross the beach and climb the small staircase at the end. Continue straight ahead to join the road, which you follow to the right for 100 metres before turning right onto the path that cuts across the bend and arrives just in front of the entrance to the Georges Delaselle botanical garden.
(2) At this point, the coastal path is signposted (orange circle). Follow it around the garden and then head east along a white sandy beach. Turn right and then left to avoid the descent to another beach and continue along the coastal path to the north-eastern tip of the island, "Porz Doun".

(4) Continue to the right to go around the tip of "Bigollé". The trail continues south-southwest for 500 metres before branching off to the right, going around a small cove.

(7) Go around it and take the path that heads east, then veers slightly north-east. Continue until you reach a junction with another path, which you should take on the right. Join the road.
(8) Turn right to cross Penn ar C'hastell, Créac'h ar C'hastrell and then Mezou Pont ar Streat Bihan. At the Y-junction, turn left.
