Tour de l’île de Groix
Qui voit Groix voit sa croix. Qui voit Groix voit sa joie, les dictons ne manquent pas sur cette île méconnue, si attachante et si dépaysante. L'île de Groix est bordée par un sentier côtier d'environ 30 km. En faire le tour en une journée est bien sûr possible mais pour en apprécier pleinement l'ambiance, il est préférable de prévoir deux jours. Port Tudy, petit village et point d'accès depuis Lorient est le lieu idéal de séjour et de départ pour ces deux journées de randonnée.

Taken over two days, stopping at Port St Nicolas and returning via the interior (half an hour).
three types of landscape: coves to the north, beaches to the east and cliffs to the south.
Don't miss the kouign amann from Groix... the best thing we had during our stay in Morbihan! And don't forget the Groix beer!

This hike can be completed in just under six hours without breaks. There are no particular difficulties apart from the distance. The western half of the route, the wild part of the island, is the most beautiful in my opinion (cliffs, moors) and the least frequented. Despite the island's tourist appeal, you can feel completely alone in the world on certain sections (outside the summer season). I did this hike in June when it was quite hot and there isn't much shade along the route, so make sure you take plenty of water, sun cream and a hat!
Make sure you check the ferry timetables if you want to see the whole island in a day. I took the first ferry from Lorient at 9am and left the island at 5.30pm. If you miss your ferry or finish earlier, you can change your ticket at the ferry terminal in the port if there are places available.

Departure from Groix (Morbihan)
This stage is dedicated to the wildest part of the island. The north coast up to Pointe Grognon has a few small coves where you can descend to sea level. From Pointe du Grognon to Port Saint-Nicolas, the coast is very rocky and jagged; access to the seashore is virtually impossible. From Trou de l'Enfer, return to Port Tudy via the small road that passes through a place called "Le Bourg".

For this second stage, after returning to Trou de l'Enfer, the Île de Groix shows a much gentler side. After a few more cliffs and coves, there is a succession of beautiful sandy beaches (Les Sables Rouges, Les Grands Sables, etc.). If the weather and season are right, it is of course advisable to pack a swimsuit in your rucksack.
=> Message posted on 28 March 2025 by a user, reporting a problem.(!) Please note that between the point (10) and the finish, the trail is closed due to a landslide by municipal decree of 26 March 2025: >Considering that, following the collapse of the cliff, the fall of rocks, the potential risk of further rockfalls due to visible cracks and the weakening of the ground between KERMOEL and PORH SKEDOUL beach, it is necessary to prohibit access to the PEN er LANN coastal path, from KERMOEL at POINTE DE SPERNEC to PORH SKEDOUL.

A partial tour of Groix Island starting from Port Tudy: part of the hike that goes around the island. The route is pleasant, the sea views superb, and the Breton style is very much in evidence. A walk that can be enjoyed with the family.

This route takes you on a tour of the eastern third of the island. You start in a relatively lush environment and continue through a sort of desert covered with gorse. You follow the very obvious coastal path and then return to the harbour via the village of Groix.

Between sea and land, the Anse de Kerguélen route takes you along sunken paths—veritable tunnels of vegetation—past meadows, ponds and marshes. Back on the shore, facing the Île de Groix, you’ll appreciate the contrast between the blue of the ocean and the white of the sandy coastline dotted with rocky outcrops.
This route is organised by Lorient Agglomération.

Close to the town centre of Lorient and the sea, this walk is ideal for families: it will take you through 89 hectares of natural environments, along paths built in the 1970s around two lakes. You will appreciate the contrast between the shady green lanes and the mirror of the sea reflecting the blue sky.
