Coastal Hikes & Walking Holidays in Brittany

If you’re dreaming of fresh sea air, dramatic cliffs, gorgeous beaches, and Celtic legends, a walking holiday in Brittany might be just what you need. This coastal region in northwestern France offers a rich blend of natural beauty and unique Breton culture, and it’s home to one of France’s most iconic hiking trails: the GR®34. It’s also the perfect hiking destination if you prefer a mix of coastal and inland circular walks.

Hiking in France: Understanding GR® Trails & FFRandonnée® Classifications

France’s walking trails are among the best signed and most well-maintained in Europe, thanks to the work of the Fédération Française de la Randonnée Pédestre (FFRandonnée®). The trail system is broken into:

  • GR® (Grande Randonnée): Long-distance footpaths marked in white and red, designed for multi-day to multi-week treks. Many cross through Normandy or connect to nearby regions like Brittany.
  • GR de Pays®: Regional loops, marked yellow and red, perfect for discovering a specific area without leaving the region.
  • PR (Promenade et Randonnée): Short walks and day hikes, often circular and marked in yellow.

Each trail is well signposted, with maps available through local tourist offices or the official FFRandonnée® site. In general, terrain in Brittany can be…

Coastal Hikes in Brittany France

The best hikes in Brittany are often found along the coast. The salty tang of the sea, the rhythm of crashing waves, and the mix of hard-working port and resort towns make each day unique. Brittany’s coastline is wildly diverse—from serene sandy beaches to jagged cliffs and hidden inlets, ideal for walkers who love big views and maritime landscapes. C’est moi!

GR®34 Customs Trail

1,243mi (2,000km)

The GR34, also known as the Sentier des Douaniers (Customs Officers’ Path), was once patrolled to prevent smuggling along Brittany’s coast. Today, it’s one of France’s most beloved long-distance trails. It starts near Mont-Saint-Michel on the Normandy border and traces the entire Brittany coast. Hike it inn to inn or choose base towns from which to day hike (which is what we did on our Brittany Coast Adventures: GR34 by Car & Foot). Some of our favorite sections include:

  • Saint-Malo to Cancale: Stunning views of oyster beds and tidal islands.
  • Dinard: Boardwalk on the edge of the English Channel with historic villas.
  • Ploumanac’h to Trégastel: Iconic pink granite rock formations.
  • Brehat Island: Lush vegetation, windy wild landscapes, beautiful homes and lighthouse.
  • Crozon Peninsula: Towering cliffs, sea stacks, and wildflowers.

GR®340 Belle-Île-en-Mer

62mi (100km)

A spectacular 4-day coastal loop trail that circles Brittany’s largest island, offering dramatic sea cliffs, golden beaches and windswept moorland. With ever-changing ocean views and lovely villages like Sauzon and Le Palais, it’s one of the most scenic and rewarding short-distance hikes in France.

Walks in Brittany's interior villages, such as Locronan, are equally special

Interior Hikes in Brittany

While the coast steals the spotlight, Brittany’s interior offers quiet beauty and cultural exploration. Walk through ancient forests, canal towpaths, and small towns with timbered houses and local markets. This is where you’ll find the truly ancient and unique Breton customs and architecture.

GR®37: Heart of Brittany

485mi (780km)

Crosses Brittany from Mont‑Saint‑Michel to Camaret‑sur‑Mer via Brocéliande Forest, Monts d’Arrée, Nantes–Brest canal, Guerlédan lake, and the Crozon Peninsula. Great choice if you want mostly interior hiking that ends with an epic coastline.

GR®38: Redon to Douarnenez

227mi (366km)

East–west interior route through Morbihan and Finistère, linking Redon with Douarnenez via Rochefort‑en‑Terre, Quimper, and Locronan (all beautiful towns worth visiting). Often combined with the GR®34 for a loop trail that offers the best of both routes.

GR®39: North–South via Vilaine Valley

217mi (350km)

Interior route connecting Mont‑Saint‑Michel alongside the Vilaine river down to Hoscas/Brière marshlands. The full route passes through the city of Rennes, which serves as the middle point dividing this long-distance hike from north to south.

GR® de Pays Tour de Brocéliande

75mi (120km)

This interior loop focuses on the legendary Brocéliande forest, famous for its misty moorlands, ancient woodlands and Arthurian sites, and historic landmarks including the Château de Trécesson.

Coastal & Interior Circular Hikes

Some of the best hikes in Brittany combine multiple GR® and GR de Pays® trails to form circular routes that blend dramatic coastal scenery with peaceful inland landscapes, offering a rich variety of terrain and cultural highlights along the way. The perfect mix if you don’t want long thru-hikes.

GR® de Pays of the Crozon Peninsula

98mi (158km)

Crozon is not to be missed, and this circular route is the best way to see the entire peninsula on foot. Mostly following the GR® 34, it weaves dramatic cliffs and bays with the wild interior woodlands, which feel like a backcountry hike.

GR® de Pays Du Cap Sizon

75mi (122km)

A similar loop to Crozon but on the more remote peninsula just south, this route features rugged coastal terrain with high granite cliffs, windswept moors, and dramatic water views. The trail passes through heathland and valleys within the protected Pointe du Raz landscape.

GR® de Pays Du Bigouden

36mi (59km)

If seeking flatter elevation, this route offers gently rolling coastal terrain with mostly level paths, dunes, beaches and farmland along Brittany’s southwestern edge. It links fishing towns including the port of Saint‑Guénolé, Lesconil, and Pont‑l’Abbé—the lively capital of the Bigouden region.

GR® de Pays Tour du Pays Malouin

62mi (100km)

A loop starting and ending in Saint-Malo, showcasing the best of the Malouin region, blending sandy coves and dramatic Emerald Coast cliffs, winding through the scenic Rance estuary and pretty villages like Cancale and Saint‑Suliac.

GR® de Pays of the Morlaix

130mi (210km)

This mostly interior loop winds along the jagged coast of Morlaix Bay, passing sites like the Château du Taureau and Pointe de Primel, then dips inland through picturesque valleys, the Cragou–Vergam moorlands, and notable villages like Guerlesquin and Saint-Thégonnec, before returning along the Penzé estuary to Morlaix. Solid choice for exploring the region near Brest and Lannion.

GR de Pays® d’Iroise

59mi (92km)

A mostly coastal loop near Brest offering dramatic ocean views over the Iroise Marine Park, including the Pointe de Corsen, Ploumoguer beaches, and historic fortifications like Fort Bertheaume and the lighthouse at Saint‑Mathieu. It begins and ends in the medieval village of Saint‑Renan.

GR® de Pays Scorff Blavet Océan

296mi (477km)

An interesting combo of 5 loop trails, beginning from the coastal town of Lorient. It alternates between sandy beaches, estuaries, and sea vistas around Lorient, Plouhinec, Guidel, and the ria d’Étel—and rolling inland through wooded river valleys like Scorff and Blavet, passing heritage-rich towns such as Guémené-sur-Scorff, Pontivy, Hennebont, and Pont‑Scorff.

Planning a Walking Holiday in Brittany

DIY Itineraries

With a good trail map or GPS app you can plan daily stages and book inns or B&Bs in advance. For luggage transport services and transfers to/from the trail, consider La Malle Postale. They serve the GR®34 and other key trails in Brittany and Normandy.

Trail apps we recommend:

  • Mapy: Excellent free app with route planning and elevation data
  • Visorando: Most widely used in France, especially for GR® trails
  • Komoot: Best for those with the paid version—excellent user reviews

How to Book Lodging

For overnight stops, use Booking.com or Expedia for guesthouses and small hotels. Airbnb is great for multi-night stays with kitchens. Be aware that not all French rentals include linens and towels or parking, so always double-check!
