This route was planned by komoot.
This trail is classified as 'difficult' by Komoot, primarily due to its significant length of 19.4 kilometers and an estimated duration of over 5 hours. While the elevation gain is modest at around 100 meters, requiring good endurance, the paths themselves are generally easily accessible and do not demand technical climbing skills. It's a test of stamina rather than technical ability.
The loop is estimated to take approximately 5 hours and 1 minute to complete, covering a distance of 19.4 kilometers. This duration can vary based on your pace, stops for views, and weather conditions.
You'll experience a varied and often shaded coastal path. The scenery includes a mosaic of environments such as sandy beaches, rocky stretches, and marshes. Expect picturesque views of the Gulf of Morbihan throughout the hike.
The trail offers breathtaking views of the Gulf of Morbihan, often called the 'small sea'. You'll pass by notable spots like Bilgroix Point, Port-Blanc Beach, and the Port of Crouesty. The route also provides glimpses of local culture, including oyster farms, and passes near historical sites like the ancient Cairn of Gavrinis and the stone circle of Er Lannic.
Yes, this loop is significantly integrated into sections of the historic GR34, also known as the Customs Officers' Path. You'll also find it overlaps with parts of the Circuit des Pointes du Golfe and the Chemin des Douaniers.
The Gulf of Morbihan Regional Natural Park is beautiful year-round, but spring and autumn offer pleasant temperatures and fewer crowds. Summer can be busy, especially on coastal sections and beaches. The park's ecological richness, particularly its bird species, makes it interesting for wildlife spotting during migratory seasons.
While the Gulf of Morbihan Regional Natural Park generally welcomes dogs, specific rules may apply to certain protected areas, beaches, or during nesting seasons. It's always best to keep your dog on a leash to protect local wildlife and ensure a pleasant experience for all hikers. Check local signage for any specific restrictions.
No, there are typically no entrance fees or permits required to access the hiking trails within the Parc naturel régional du Golfe du Morbihan. The park is dedicated to preserving its natural and cultural environment and is freely accessible to the public. However, always respect local regulations, especially concerning nature protection.
Specific parking information for the exact starting point of this loop isn't detailed, but Arzon and nearby coastal towns like Port du Crouesty offer various public parking options. It's advisable to look for parking near the main access points or popular highlights mentioned, such as Port du Crouesty, which is a significant hub.
Public transport options in the Gulf of Morbihan region, especially to smaller coastal areas like Arzon, can be limited. Buses might serve the main towns, but direct access to specific trailheads might require a combination of bus and a short walk or taxi. Checking local bus schedules for the Morbihan department is recommended.
The park is a haven for diverse flora and fauna, particularly bird species, as it's a significant stop for migratory birds. You might spot various waders, seabirds, and raptors. The park's emblem is the speckled seahorse, highlighting the importance of marine preservation, though spotting one in the wild is rare.
Weather and forecast not really promising this morning, but largely passable in the end.🌥️☁️
Located at the lower 'entrance' to the Gulf of Morbihan, the Rhuys peninsula is a popular holiday area - there are many holiday homes and the harbors are full of sailing boats. The GR34, on which we have already undertaken several coastal hikes in Finistère, leads around the peninsula. Due to fixed evening dates 🍽️ we didn't extend our tour too far - more info on the picture comments (when I get to it, I'm quite behind)
A real ode to the beauty of the place. We could see the last movement of Beethoven's 9th symphony which makes everyone agree (movement moreover taken over by the European Union to make it its official anthem), proclaiming the ideal and human fraternity ( according to a poem by Frédéric Von Schiller in 1785). Difficult to burst photos as it seems incongruous to capture the real essence. But it's instinctive and sometimes necessary to remember those magical moments! And what about the song "La mer" by Charles Trenet: "The sea that we see dancing along the clear gulfs ...." or rather the gulf that we see dancing along the sea as if to be tamed . Rehabilitation that could emerge by one of our contemporaries, but it is not topical.
A beautiful walk, I think the landscape would be even prettier at high tide, beautiful photos to take in perspective
This circuit offers a pleasant coastal walk. Due to its location, you'll enjoy beautiful views of Locmariaquer, Larmor-Baden, and many islands in the Gulf of Morbihan. Note that the coastal paths are very narrow and can be dangerous (near cliffs). The signage is adequate and runs in both directions, but it could be strengthened. It shares a section with the GR34. This fairly long loop does not have a shorter version. A few benches and picnic tables mark the route for resting. Throughout this loop, you'll see a dolmen, a cairn, a church, a chapel, pretty little beaches, mills, and fountains. This circuit starts from the small parking lot located on Rue du Presbytère. Unfortunately, I regret that there is no map of the circuit at the beginning. Also, a larger parking lot would have been appreciated as spaces are really limited!
A magnificent view of the Gulf of Morbihan. With access to superb little beaches. Ideal for a short picnic break
Very nice round, well signposted, right on the water, at high tide small areas at the Pointe de Kerners can only be passed through the water or you can make a small curve inland. Beautiful view of the Gulf of Morbihan, with considerable currents due to the ebb and flow. You can find the description on the website of the tourist information https://www.golfedumorbihan.bzh/randonnee/randonnees-presquile-rhuys/rando-pointes-du-golfe/ On the way there are always benches / picnic areas and also one or the other toilet. At the end of the hike still on the Gulf: bistros, creperies and bakers.
