Want to combine nature and culture on your holiday in Brittany? Then the Sainte-Barbe loop is for you!
The walk takes you gently away from the coast for a welcome stroll through the peaceful (and slightly wild!) countryside. Along the way, embankments and ferns accompany your every step, until you reach the famous chapel of Sainte-Barbe, protector of sailors. Set high up on the hillside, you can’t miss it as you scan the landscape! Fresh undergrowth, small hamlet roads and views over the Trégor countryside punctuate this walk, much to the delight of those who (finally) want to take a deep breath of fresh air.
Anecdote: The thermal baths, dating back to 50 AD, were rediscovered by chance in 1892. Today, they offer some of the most beautiful scenery on the coast! And yes, hiking in Brittany is always worth the effort.

Have you always heard about the legends of Brittany? What if we told you that you could walk in their footsteps (literally!)? Plestin-les-Grèves’ Lieue de la Grève is the ideal starting point for your walk! Take a steep path to the top of the Grand Rocher. The good news is that once you’ve made the climb, you’ll be rewarded with a superb view over the bay! This is also where the legendary atmosphere is felt: Saint Efflam is said to have helped King Arthur to slay a dragon at the foot of the Great Rock. You might see a few scales lying around…
Depending on the tide, the landscape changes completely: a mirror of water at high tide, a sandy desert roamed by birds at low tide. As for the chapel of Saint-Efflam and its miraculous fountain dedicated to the saint, the legend lives on. Saint-Efflam is said to have conjured up a spring so that King Arthur could drink during his battle with the dragon! Saint-pas.
A bald man who can: Do you hear a few flapping wings on your walk? You’ll probably see a few bats around the Grand Rocher. This protected site is home to many species of bat! Brittany has never been so wild.

For an intimate look at Plestin-les-Grèves, take a walk around the Saint Haran loop. Your walk will take you past ancient hamlets, narrow paths lined with embankments and small rural chapels. The route leads all the way to the Saint-Haran chapel, nestling in a natural setting. Along the way, you’ll be accompanied by the lapping of the Douron, a coastal river. The perfect way to take it easy in Brittany.
Did you know? The estuary is a veritable wilderness paradise for migratory birds and aquatic wildlife. So don’t forget to pack your binoculars!

Walking on the cliffs of Tredrez
|
Welcome to one of the largest wilderness areas in the Côtes d’Armor: the Trédrez cliffs! On this magical walk, the path overlooks the sea in a succession of viewpoints, each more impressive than the last, from the Bay of Lannion to the Lieue de Grève. If you’re looking for the big show, Brittany’s the place to be! The coastal scenery is untouched, with barren moorland and wind-sculpted rocks. It’s sure to leave you breathless! And on windy days, you’ll feel the power of the Breton coastline even more. A hike as wild as it is unmissable.
Tip: This is the most strenuous of the four walks, with a positive difference in altitude of over 300 metres! Rewarded by some stunning scenery, of course. At low tide, go along the shore to see the Croix de Mi-lieue. What’s more, it’s a shortcut…

Plestin-les-Grèves offers a wide range of walks between the sea and the countryside! Some of the most popular are: the Saint-Efflam loop around the bay, the Sainte-Barbe loop in the valleys of the hinterland, the Saint-Haran loop in the heart of the Breton hamlets and the Trédrez cliffhike , which offers a breathtaking view of the sea.
Alternatively, take a walk around the island of Bréhat, with its mild climate all year round, or the Renote peninsula, with its unusual granite boulders. Hiking between Perros-Guirec and Trégastel is also a must on the Pink Granite Coast (perfect for seeing the famous Ploumanac’h site for yourself!). In short, Brittany is at the cutting edge when it comes to hiking.
Yes, you can explore the Breton countryside on the trails around Plestin-les-Grèves with your family. Here are some ideas:
Whichever hike you choose, we recommend that you always check the distance and gradient before setting off, so as to choose a route that’s suitable for children.
Warning: The summit of the Grand Rocher and the cliffs of Trédrez have steep slopes and steep areas that require extra supervision for budding hikers.
Yes, the path along the cliffs of Trédrez-Locquémeau offers a spectacular walk above the sea. The route offers numerous viewpoints over the Bay of Lannion and the wild coastline. It’s an ideal walk for lovers of seascapes and photography. Don’t forget your camera!
Following the right routes is as easy as 1-2-3 in Brittany! There are two types of signposting for the walks on offer:
Hiking is possible all year round!
However, the ideal period is from May to October. Spring brings an explosion of colour on the moorland (gorse and broom), while autumn adorns the Douron valleys with orange hues. In winter, the paths along the Corniche de l’Armorique remain magnificent, but be sure to bring windproof equipment, as the coastline is exposed.
For most of the higher paths (cliffs, ledges), the tide has no impact. However, if you are planning to cross the Lieue de Grève or walk along the lower reaches of the Douron estuary, it is essential to check the tide times. The sea rises very quickly over these flat stretches of sand.
Dogs are allowed on footpaths (GR®34 and inland paths) provided they are kept on a lead, in order to protect local wildlife and sensitive natural areas.
Important note: Access to the Lieue de Grève beaches may be regulated or prohibited to dogs during the summer period (July-August). Check the municipal by-laws in force.
Each loop has free car parks in the immediate vicinity:
The duration varies according to the excursion chosen: allow around 2 hours for an outing around Sept-Îles, or between 1h30 and 2h. There are many walking routes on offer on the Pink Granite Coast, from coastal paths to wild valleys and picturesque villages.
The Tourist Offices of the Pink Granite Coast can advise you and provide maps to help you explore the different itineraries.
