Backpacking on the GR 34

From Guidel to Port‑Louis via the Gâvres peninsular

From April to October

Sample a variety of landscapes in Lorient. From the Laïta river to the Petite Mer de Gâvres, stroll along the fine sandy beaches of pleasant seaside resorts, popular with surfers: Guidel, Ploemeur and its Fort Bloqué, Larmor-Plage, etc. With a view of the Lorient roadstead, the citadel of Port-Louis, and Groix island in the background!

01 Step 01

A day at Guidel Plage

Guidel-Plage is a pretty little seaside resort in Southern Brittany. From Lorient, you can get there by bus or taxi. When you arrive, you’ll be greeted by 5 km of beach. Go on, take a dip! Then head to the marina on the Laïta estuary. It’s an unspoilt, meandering ria, of which Brittany has many.  It’s also a true paradise for birds. Hop on a tour boat with Laïta Croisière to discover the fauna and flora. Another good idea: rent a canoe/kayak or SUP from Laïta Location and gently coast upstream, between reeds and sandbanks.  Or perhaps thrills are more your thing? Try wake-boarding with Fun 56. An adrenaline rush is guaranteed!

From Guidel to Larmor-Plage

Departure: Guidel marina 
Arrival: Port Maria in Larmor-Plage   

Warm up your calf muscles, it’s going to be a long day. First, discover Guidel beaches in Plœmeur, across dunes and flowering moors. Fort Bloqué, on its rocky island, is worthy of a postcard!  Continue towards Kaolins beach, with bright white-clay sand, and pass from one cute little port to another: Courégant, Kerroc’h and Lomener… Its sea wall is a storm hotspot! Cross the Kerguelen ocean park, rich in maritime fauna and flora. That’s it, you’ve reached Larmor-Plage. Can you hear the café terraces with their sea views calling to you? Yes, you deserve a little drink!


“The” place for water sports 

Kerguelen is the ideal spot to enjoy water sports. Take a dinghy, SUP or windsurfing lesson at Kerguelen Sport Océan. You can also try surfing at Fort Bloqué, with ESB.

From Larmor-Plage to Lanester

Starting point: Port Maria, Larmor-Plage 
Arrival: Auberge du Chemin de Fer, Lanester 

The seaside resort of Larmor-Plage, with its seafront promenade and villas from the 1900s, oozes charm! As you walk alongside Toulhars cove, enjoy the stunning view of the Port-Louis citadel and the Lorient roadstead. After Kermélo bridge, you’ll reach Lorient-La Base. With its bar and restaurant terraces, its shops and even a concert hall in a former bunker, it’s the new trendy neighbourhood. Here you are at the heart of the Offshore Racing Centre! Do you want to take time to stroll around the “town with 6 ports”? Then you can stop here (stage shortened to 7 km). Otherwise, go over the River Scorff on Pont des Indes bridge. Lanester is just on the other side.

Hoist the sails! 

Put on a life jacket and step into the shoes of an offshore racing skipper. From the jetties of Lorient-La base, embark on a monohull for a sailing trip around the Lorient roadstead. It’s a must after visiting the Cité de la Voile Eric-Tabarly.

From Lanester to Port-Louis

Starting point: Auberge du Chemin de Fer, Lanester 
Arrival: Port de la Pointe, Port-Louis 

Today, you have a choice: the long or short version. Both start with one of the most bucolic and unspoilt sections between Kervignac (after Bonhomme bridge) and  Locmiquélic. Walk alongside the Blavet, passing through picturesque hamlets, marshes, ponds, etc. Signs help you identify the migrating birds that nest here. At the Pen-Mané jetty in Locmiquélic, continue on the GR® 34 or take a bus, or even better a boat-bus (weekends), to Port-Louis La Pointe. That’s 6 km less for your legs! Did you stop in Lorient the day before? Here too, you can embark, at the fishing port or Quai des Indes, for a crossing to Port-Louis La Pointe. A day off will be good for those who are less sporty.

Slow navigation on the Lorient roadstead 

Discover the Lorient roadstead on the water. At Locmiquélic, on Key Largo, hop on a hybrid boat that can take up to 9 passengers. Departing from Lorient-La Base or Port-Louis, the Escal’Ouest company also proposes guided and eco-sensitive outings. Another option is an exploration of the maritime Blavet river on a Tjak (Dutch sailing boat) with Au fil de l’eau.

Port-Louis and the Gâvres peninsular

Six minutes is all it takes to cross between Port-Louis Locmalo and the Gâvres jetty. Boat-buses make the return journey several times a day, every day and even on Sunday. The Gâvres peninsular can easily be discovered on foot, and is well worth the detour! On one side, the Gâvres sea, resembling a lagoon; on the other, the ocean lined with wild dunes… You’ll feel as if you’re nearly at the edge of the world. Follow the coastal path to discover the Goërem dolmen, and breathe in the salty ocean air at Fort de Porh Puns (open at weekends). Lose yourself in the little streets, too, with its typical fishermen’s houses. It’s an enchanting walk!

Fly above the water 

Are you ready to take off? The Gâvres peninsular is a paradise for kite-surfers. It’s the perfect opportunity to try it (or to hone your skills) with You Kite. You can also test the wing-foil, “the” new trendy water sport, with PLS Voile. Are you a fishing fan? Go on a sea fishing trip for sea bass and sea bream with Lorient Passion Pêche.

On Groix Island

Do you want your trip to last longer? In spring or autumn, treat yourself to an island break on Groix. Embark at the Lorient maritime station for a 45-minute crossing. There are many coastal and inland circuits on the island. For example, head to the surprising convex beach of Sables-Blancs, the typical village of Locmaria or the lighthouse at Pointe des Chats. From the village, you can also reach Saint-Nicolas harbour and Trou de l’Enfer, on the unspoilt coast. The full tour of the island is 27 km.
