Description of the walk

Start: The walk will start before the village of Bourgerel, at the roundabout (car park) of the roads "Route de Bourgerel" and "Route de Roguedas".

(S/E) With your back facing the car park, turn left onto the road "Route de Roguedas", direction Penboch / Benalo. Cross Benalo to the crossroads.

(1) Turn left onto the road "Chemin de Doaren Quistinen". Continue to the end of this path to find the KerHenri dolmen (only visible when the grass is cut).

(2) Turn left onto the lane "Chemin du Dolmen er Roch, leaving two roads to the left and a path to the right. Cross Kervadec town, go straight ahead at the junction to reach another junction.

(3) Leave the road on your left and go straight ahead, cross Keranna town and continue to the junction of two roads (left towards "le Vincin").

(4) Turn right towards Roguedas town on the GR®34. Follow the road for 500 m and take the coastal path on the left. Follow the coastline and the GR®34 (around the gulf).
After the descent, follow the dike along the wall, then the path bends to the right to join a tarmac road.

(5) At the junction, turn left and continue along the coastal path. It bends to the right and reaches a 4-ways path junction, at Kerguen town.

(6) Turn left and immediately left again at Haliguen (towards Penboch).

(7) At the bend at Roguedas, turn left onto the path leading to the coast (here to shorten the route, continue straight on to Benalo, following the GR® signs to the car park).

Reach the beach and follow it to the right (beware of certain tides, high tides or high water, the way may be tricky, you'll have to go inland and follow the GR® indications).
Leave the path on the right that leads up to the Penboch campsite and continue along the coastline.
Leave a road on the right and continue for about 150m to a small grove.

(8) Take the path up to the right. Go around the building and turn left to follow the path and then the road (named "impasse de Bourgerel"), cross Bourgerel to reach the roundabout where the car park is. (S/E)

A lovely walk – we set off from Penboch and walked as far as Pointe d'Arradon
At high tide you have to be careful; we were just about able to get through
The sky was blue, as was the sea
This walk is easy; there were lots of people on the path, which was very pleasant

This circuit has been closed by decision of the Arradon Town Council since May 2025
The closure is located at the start of the route at a place called "La Chesnaie" and extends to "Conleau"
On the map, the closure extends from point 4 to point 5.
It seems difficult to find a parallel route to this closure

Very nice route, it's a shame there are these asphalt sections from the halfway point between 2 and 3 until after 4, then between 6 and 7 (but not much choice for making a loop); the start of the GR 34 along the seafront after 4 is quite muddy; I didn't find junction 7 of the route as indicated, which seems closed, but you continue a little along the road then find the beach on the left; For this part of the route you don't need a high tide as you walk on the beach / stones with seaweed (it doesn't last too long, about 600m before you find a stony path overhanging the beach); lastly, for number 8, the junction no longer seems to exist as indicated here, but I turned back for 100m and you're back on the final route; in short, a lovely walk that I'd gladly do again, as it's not too difficult, varied, with beautiful views over the gulf, and lovely beaches (that I hadn't imagined at the bottom of the gulf).

Thank you very much for this lovely walk, which offers beautiful views of Conlau, Séné with Port Anna and above all the Maison Rose de Port Anna.
I also turned off at point 3 to join the coastal path through the woods.
I should point out that at point 7 a gate prevents you from going down to the coast, so I had to continue to the first path on the left, but it was high tide and I had to take the GR back to point 1 and then to the car park.
This walk also enabled me to see the retreat of the coastline, with the many trees (oaks and pines) that have fallen into the Vincin as a result of bank erosion.

Nice walk
Note: the starting point: there is little chance of getting it wrong, but the car park is a crossroads, not a roundabout.
The Kerhenri dolmen was effectively hidden by the tall grass from the path, but a path was cut through the field to get to it: it's not impressive, but it's worth a look all the same.
Tip: after the dolmen (point 2 on the map), go straight ahead (black dotted path on the map) to pick up the GR 34 circuit after point 4: this avoids a whole stretch of road which can be a little dangerous with cars passing, as the roadside verges are not very wide.
In this case, turn right when you reach the tarmac road (GR34) or continue the route and join the coastal path a little further on.
In Kerguen, before point 6, it is possible to cut across the beach, at least if the tide is out.

A very pleasant walk.
The fork at point 3 does nothing to detract from the outing.

We only did part of the route between Penboch and Conleau Island (opposite the island). It was great; we stayed by the sea on the way out instead of taking the GR (Kerguen, Haliguen).

Some very nice seaside sections. You can turn right in 3, or even 2, to avoid the tarmac. We couldn't find the passage at Roguédas and had to take the road.
Overall, a fine walk.

A significant amount of walking on the road can be avoided. After Kervadec, at marker 3 (Keranna), take the dotted path on the map. This is a very pleasant path, which leads directly to the coastal path!

This little shortcut makes the walk absolutely superb...

Hello Pascal79,

Thanks for your comment on this walk. Just a comment on the fact that not everything is on the GR34 (it's not called the customs path) but that was necessary if you wanted to do a loop. Alternatively, you could do an out-and-back, but I don't like going backwards. The circuit is still 6 km of the 9 on the GR34 by the sea.

It's a shame that not everything is on the customs path, you have to go up to 4, but it's worth it. From 4 to 8 it's magnificent.

Lovely walk along the river le Vincin, Conleau and the bottom of the gulf.
It's a shame there's a large section on the road that doesn't help, but you have to make a loop.
Perhaps you could go straight on at the dolmen (2), then turn right and rejoin the GR at point 4?
Very pleasant all the same.

A very nice walk, especially along the dyke, with superb scenery. Despite the heat, most of the route is shaded.
