The GR34 at Trestel: A Hiking Guide on the Pink Granite Coast

Explore the GR34 from Trestel! Our detailed guide to the sections towards Port-Blanc and Perros-Guirec: elevation, stunning views, and practical tips.

The GR34, also known as the "Customs Officers' Path," is one of Brittany's treasures. This long-distance hiking trail follows the entire Breton coastline, offering breathtaking panoramas. The good news? It runs right past your holiday accommodation in Trévou-Tréguignec, along the magnificent Trestel beach. Whether you are staying at the Maison des Mouettes with its stunning sea view, or enjoying the peace and quiet of L'Appart'24 or La P'tite Maison, the trail awaits.

This article provides a detailed guide to the sections accessible from Trestel, heading both west and east, for half-day or full-day hikes.

Heading West: From Trestel to Port-Blanc (Moderate Difficulty)

This section is arguably the most family-friendly. The path is well-marked and the elevation gain is reasonable, while still offering spectacular viewpoints. Allow several hours for the round trip at a leisurely pace.

From Trestel Beach to Pointe du Royau

Starting from the western end of Trestel beach, the path rises quickly to offer an initial panoramic view of the large sandy bay. You will walk along secluded coves with turquoise waters. The path winds through gorse and heather, with the sound of the waves as a constant backdrop. It's a perfect warm-up, where the beauty of the landscape is revealed with every step.

The Port of Royau and Seabirds

After a short walk, you will reach the charming little port of Royau. This peaceful haven, sheltered from the prevailing winds, is an ideal place for a break. A little further on, the path bypasses a rocky promontory where many seabirds nest. Depending on the season, you can observe cormorants, gulls, and other seabirds. The trail becomes a bit wilder here, with a few easy rocky passages.

Pointe du Château and Arrival in Port-Blanc

The highlight of this walk is the arrival at Pointe du Château, which overlooks the port of Port-Blanc. The view is striking: it embraces the port and its string of islets, with the Sept-Îles archipelago in the background. Then, descend towards the port itself, with its chapel and typical fishermen's houses. It's the perfect spot for a gourmet break before heading back to Trestel.

Heading East: From Trestel to Port-l'Épine (More Demanding)

This part of the GR34 is more athletic. The elevation change is more pronounced, with a succession of climbs and descents. But the effort is well rewarded with landscapes emblematic of the Pink Granite Coast.

From Trestel to Vaisseau Beach

Starting from the east of Trestel beach, you first follow the road overlooking the bay before rejoining the coastal path. The trail climbs and offers plunging views of the emerald sea. You will pass through a more wooded area before descending to the discreet cove of Vaisseau Beach, a small gem set among the rocks.

Pointe de Port-l'Épine and the View of Ploumanac'h

This is where the show really begins. Upon reaching Pointe de Port-l'Épine, you discover one of the most beautiful views in the region. In front of you, the Mean Ruz lighthouse stands amidst the granitic chaos of Ploumanac'h. The pink rocks, sculpted by millennia of erosion, create a magical setting, especially in the morning or evening light. Take your time to admire this picture-postcard landscape.

Connection to Perros-Guirec

From Port-l'Épine, the trail continues towards Perros-Guirec. It undulates through the moorlands and offers ever-changing perspectives on the coast. This section allows you to join the famous Ploumanac'h trail for a longer hike, discovering the rocks with evocative shapes (Napoleon's Hat, the Bottle, etc.).

Practical Tips for Your Hike

  • Equipment: Be sure to bring good walking shoes, water, sunscreen, and a hat, even if the weather is cloudy.
  • Tides: The GR34 is a coastal path. Although most sections around Trestel are accessible at any time, it is always wise to check the tide times. This can affect access to some small coves. For reliable information, you can check the tide tables via SHOM.
  • Respect the Environment: The trail crosses fragile natural areas. Stay on the marked paths, do not pick flowers, and take all your rubbish with you. The beauty of the site depends on everyone's consideration.
  • Welcome Basket: Don't forget to dip into the welcome basket provided by Janine and Guillaume to take some products from a local farm. Nothing beats an organic fruit or vegetable to regain your strength!
