GR34 – The Customs Officers’ Path around Carnac & Quiberon

Beaches & nature
Écrit par

The GR34, also known as the Sentier des Douaniers (the customs officers’ path), follows the entire Breton coastline for more than 2,000 kilometres, from the bay of Mont-Saint-Michel to the Saint-Nazaire bridge. Around Carnac, La Trinité-sur-Mer and the Quiberon peninsula it offers some of the most spectacular views in Morbihan: jagged cliffs, wild coves, dunes, fine sandy beaches and authentic fishing villages. It is an ideal route for day walks as well as longer hiking trips.

Around Camping Les Druides

From Camping Les Druides in Carnac, several sections of the GR34 are easy to reach by car or bike in a few minutes. These stretches reveal the full diversity of the landscape: indented coastline, sheltered bays, harbours, megaliths, marshes and granite headlands.

Main areas to explore:

  • Carnac – beaches and the coast towards La Trinité-sur-Mer (3–5 km of coastal path)

  • La Trinité-sur-Mer – banks of the Crac’h river (salt marshes, marina)

  • Quiberon peninsula – Côte Sauvage (15 km loop possible)

  • Étel ria – ria landscapes and typical islets (including Saint-Cado)

1. Carnac & La Trinité-sur-Mer – gentle coastline and sheltered harbours

Carnac-Plage and Beaumer

Leaving Carnac, the path follows the beaches of Beaumer and the Grande Plage, with an open view over the bay and the offshore islands. The terrain is gentle and accessible to everyone, ideal for a family walk or to warm up the legs.

Highlights:

  • South-facing fine sandy beaches

  • Panorama over Quiberon Bay

  • Easy access from the campsite (a few minutes by car or bike)

  • A route of about 3 km between Carnac and La Trinité-sur-Mer

Towards La Trinité-sur-Mer

Continuing east, the route reaches La Trinité-sur-Mer, a marina with a worldwide reputation for sailing. The GR34 follows coastal tracks and small roads along the banks of the Crac’h river, with views of the pontoons, the racing yachts and the old Kervillen salt marshes.

Things to see:

  • La Trinité-sur-Mer harbour and the Môle Éric Tabarly

  • Kerisper bridge (panoramic view)

  • Kervillen salt marshes (restored) and the beach of the same name

  • Pointe de Kerbihan

2. Quiberon peninsula – the Côte Sauvage

An emblematic stretch of the GR34

The Quiberon peninsula is one of the most spectacular sections of the GR34. The west-facing stretch known as the Côte Sauvage alternates jagged cliffs, rock arches carved by the waves, isolated coves and dizzying viewpoints over the Atlantic Ocean.

Characteristics:

  • Well-waymarked path (red and white GR markings), but exposed to the wind

  • Sometimes stony, rocky terrain, so bring good walking shoes

  • Many possible starting points: Portivy, Beg en Aud, Port Bara, Port Blanc (with its famous arch), Pointe du Conguel

Loop ideas

  • Tour de Quiberon: a full 15 km loop for cyclists and walkers, or a shorter variant cutting across the interior

  • Portivy – Côte Sauvage loop: out and back along the ocean, or a loop returning inland

  • Plouharnel – Penthièvre – start of the peninsula: alternating dunes, bay beaches and views of the isthmus

These walks combine the open ocean, the beaches of Quiberon Bay and a wild atmosphere in a few hours on foot.

3. Étel ria & Saint-Cado – a ria atmosphere

Typical ria landscapes

North-west of Carnac (about 20 km by car), the Étel ria offers a different atmosphere: a winding arm of the sea, mudflats uncovered at low tide, oyster beds, salt meadows and small harbours. The GR34 partly follows the banks of this ria, with superb views over the meanders of the river and the powerful currents rushing through the narrow passage of the Lorois bridge.

The islet of Saint-Cado

The islet of Saint-Cado, in Belz, is reached directly from the GR34. You cross a small stone bridge (the famous Devil’s Bridge of legend) to find a 12th-century Romanesque chapel, a picturesque fishing village with flower-filled lanes, and the famous blue-shuttered house of Nichtarguer perched on its rocky islet.

Possible routes:

  • The Étel river and Saint-Cado: a 13.5 km loop

  • Short Étel ria loop: 15 km

  • GR34 westwards to the Lorois bridge (2 km), with a spectacular view over the ria
