Park in the car park at the port of Melon, in the commune of Porspoder.
(S/E) From the car park, head towards the point opposite Melon Island via a track that leads to a slipway. Continue along the path that passes near an old gatehouse and arrive at the top of a rock offering a view of the island and its old granite quarries.
Descend to the shore to access the island, which is only possible at low tide and preferably when the tidal range is high.
(1) Walk around the island clockwise, preferably along a rough path, to discover a menhir and a beautiful dolmen in the centre. On the landward side, you can look out over the old granite quarries where blocks are still scattered. Cross back over to return to the car park (see Practical Information).
GR ®34 Marked in white and red
(S/E) Set off to the left along the road running alongside Melon harbour, keeping to the pavement on the right-hand side, which is safer than the side facing the sea.
(2) Turn left at the sign for Hent Kervéoc, pass by a wash house and continue on theGR® which heads north along a small road extended by a path. When you reach a fence, turn left then right onto a tarmac section.
(3) Follow this small road for about a hundred metres, then turn left onto the path that leads to the small port of Mazou. Note the piles used to moor boats. Continue along the coastal path that runs alongside the port and joins a road with a small car park.
(4) Continue along the wide, north-west facing track. As you approach the next headland, keep to the left, deviating slightly fromthe GR® to follow the path closest to the sea. Rejoin theGR® and continue towards Pointe de Garchine. On the right, you will see a large antenna and the fence marking the boundary of a naval military base. Arrive at the rocky point, which offers a view of the Phare du Four lighthouse.
(5) Turn right, leaving the coast and theGR® trail, and walk up towards a car park along the fence of the military base.
Yellow marked PR
Walk up to a cross road.
(6) Turn right and pass in front of the entrance gate to the naval base. On your left, note the large modern houses, which contrast with the small hamlets you will pass through later. You will arrive at a small road marked "no entry for vehicles over 3.5 tonnes".
Off the marked route
Take this small road which passes through the hamlet of Kermerrien with its beautiful old granite houses, then Kerharan, ignoring all roads on the right and left.
(7) Walk along a high stone wall that hides a large property (an old manor house?). You will arrive at the fork in the road from the outward journey.
(3) Turn right onto a short stretch of road that leads to a house (beautiful view of Mazou harbour). Turn left and look for the sign for the "sentier côtier" (coastal path).
(8) Turn right and take the narrower path that follows the coastline more closely. You will come to a rock topped with a cross, offering a beautiful view of Melon Island. Continue along this coastal path, which widens and ends at a property.
(9) Descend to the seafront to go around it, then climb back up to the left to rejoin the GR®.
GR®34 Marked in white and red
Follow the same route back to the harbour car park. On your left, you will see the Espace Herri Léon, a former seaweed burning plant, converted into a chapel in 1951 and now a socio-cultural centre.
The car park is on the right (S/E).
s should be done at low tide! Not to mention Melon Island, which is inaccessible at high tide, several passages along the coast are a bit tricky (you have to climb over low walls) or even impossible. The last point (9) is impassable and requires a long detour.
