Cycling in BrittanyDay 2 | La Côte d'Ajoncsfrom Tréguier to Perros-Guirec
Departure
Tréguier, Petite Cité de caractère
On the Place du Martray, in the heart of Tréguier’s Petite Cité de Caractère, stands the imposing Cathédrale Saint-Tugdual, one of the city’s treasures accumulated over its rich history. Strategically located on the Jaudy estuary, the town is one of the 7 historic bishoprics of Brittany, linked to the 7 founding saints, and is also the town of Ernest Renan, whose birthplace you can visit. And before you get on your bike, don’t miss the superb Gothic cloister next to the cathedral.



Step 1
Kestellic Gardens
Located on the banks of the Jaudy river, the Kestellic gardens stretch around a superb manor house, on a sloping, undulating estate. Strolling through the 3 themed gardens, you’ll find a wide variety of species and be taken on a sensory journey.
Step 2
Port de La Roche Jaune
Arriving at La Roche Jaune, you can turn right just past the Saint Guéno chapel to reach the small oyster port. From here, you can enjoy a lovely view of the estuary on one side, and the sea on the other.
If you’d like to sample the oysters from the oyster beds at the mouth of the Jaudy, visit the cabane à huître!




Step 3
Kayak trip around the island of Er
Leaving the village of Plougrescant, head down to Beg ar Vilin, enjoying a superb view of the mouth of the Jaudy. For another sporting experience, this time by the sea, take a kayak out to the Isle of Er and enjoy the coastline from the sea.
Step 4
La Chapelle Saint Gonery
What stands out at first glance, of course, is the chapel’s surprisingly leaning steeple, particularly imposing in the saint’s enclosure. But the building, whose oldest part dates back to the 11th century, also boasts rich furnishings and remarkable painted ceiling decorations. A yew tree several hundred years old completes the picture.








Step 5
Le Site du Gouffre
Close to the Pointe du Château, the most northerly point in Brittany, the Gouffre site unveils its scenery of rocks sculpted by the elements, moors and lagoons formed by several small dune belts. Take the time to put down your bike for a moment and discover this site of grandiose landscapes, and don’t hesitate to visit the Maison du Littoral to learn more about these fragile ecosystems.
A 6km discovery trail is also available from the Maison du Littoral.
Step 6
Port Blanc
After passing the village of Buguélès and crossing the Pellinec cove (or going around it at high tide), you reach Port Blanc, facing its archipelago of islets. The Rocher du voleur (Thief’s Rock) offers a particularly remarkable panorama, and this strategic location was once used to defend access to the port. On the beach, you’ll notice the Sentinel Rock, topped by a sentry box housing the statues of the Virgin Mary and Saint Tugdual, who seem to tirelessly watch over this coast, where the landscape is constantly changing with the tides and the light.
Climb a few steps to discover the Notre Dame de Port Blanc chapel, partly buried in the ground.

Step 7
La Chapelle Saint Guénolé
If you take the main Vélomaritime route south of the village of Penvénan, you’ll soon reach the chapel of Saint Guénolé. In the distance, you can see the sea from the beach at Trestel, as well as towards Le Royau, access to which is signposted 2km away. Descending into the valley, you take a small forest track that leads to the Bois Riou pond.
Arrival
Perros Guirec Bay
This stage ends along the bay of Perros Guirec, home to its harbour, and at the far end of which is the Lenn marine pond, formed by a small dune belt. It’s a great place to spot seabirds.
