Lezardrieux lies right on the Trieux. The river shapes a wide range of discoveries here: walking paths and viewpoints, hikes along the estuary, and trips out on the water. There are also chapels with remarkable furnishings, a weekly market, and practical considerations to bear in mind when planning. To help you choose your activities, there are clear differences: the hikes vary in length and duration, while the boat trips offer either guided excursions or the chance to take part in sailing manoeuvres.
Riverside paths, viewpoints and hikes
Bois de Lan Goc is open to everyone and offers walking paths in peaceful natural surroundings. A viewpoint and picnic tables look out over the marina. Near the Les Perdrix beacon is a protected botanical area, where information panels introduce around 100 local plant and animal species. From this area, a hiking trail of about six kilometres continues towards the village of Kermouster. One hike begins at the port of Lezardrieux and follows the Trieux estuary to the hamlet of Kermouster, which offers exceptional views of the estuary and the Bréhat archipelago opposite.
For a longer circular hike, the Boucle de Kermaria is another option: it is 11.5 kilometres long, rated moderate, and takes about three hours. At high tide, the coastal section below the Moulin Ă Mer is impassable on this route; a signposted high-tide alternative is available. The two hikes therefore differ both in their stated length and in that an approximate duration and difficulty rating are provided for the Boucle.
Swimming is possible at Goas Luguen beach near Kermouster at high tide, but there is no lifeguard supervision. Bear this in mind when planning a stay by the river. If you prefer to explore on foot, you can choose between the approximately six-kilometre trail towards Kermouster and the longer circular hike, without assuming a walking time that has not been specified for the shorter trail.
Chapels, church and local history
The Chapelle Saint-Maudez de Kermouster was rebuilt in 1740 on the site of a 12th-century oratory. It houses a 15th-century wooden Christ, nine polychrome wooden statues from the 17th and 18th centuries, a painting of Mary Magdalene and several ex-votos. Its age, architectural quality, religious furnishings and numerous votive offerings make the chapel remarkable. The Pardon de Kermouster takes place on the first Sunday in September.
The church of Saint-Jean-Baptiste also offers a distinctive architectural landmark: it dates from 1580 and 1858 and has a striking bell tower typical of churches in the Trégor. Since 1840, the Pont Saint-Christophe has been an important crossing between Trégor and Goëlo. The statue of Saint-Christophe has been listed as a historic monument since 1978 and depicts Saint Christopher, patron saint of travellers and boatmen.
The Chapelle Saint-Mahurin de Kermaria dates from 1783 and is set amid lush greenery and flowers. It is open to the public only occasionally, so check access before visiting. These religious sites therefore differ not only in age and furnishings, but also in that this chapel has explicitly limited opening.
Boat trips and the Phare de Bodic
Le Passeur du Trieux offers guided boat trips on the Trieux, a designated Natura 2000 site, departing from Lezardrieux. Trips last 1 hour 15 minutes, 2 hours or 4 hours. Durations and availability may vary seasonally; check current options in advance. Voiles & Traditions also departs from the port of Lezardrieux and offers sailing trips to explore the Bréhat archipelago. Passengers can take part in manoeuvres and take the helm. This offer is seasonal; check before booking.
The Trieux is navigable for 17 kilometres between the entrance marked by the Phare de la Croix and the river port of Pontrieux. The route also passes the marina at Lezardrieux. The 23-metre-high Phare de Bodic, together with the Phare de la Croix off Ploubazlanec on the opposite side of the Trieux, marks the entrance to the river. It replaced an earlier lighthouse built in 1867, which was destroyed by the Germans in 1944. The lighthouse is fully automated; the last lighthouse keepers left in 2015. Access is via the hamlet of Bodic on the road towards Lanmodez. The Phare de Bodic will be closed to visitors throughout 2026; before travelling at a later date, check whether visits have resumed.
Friday morning market
The Marché de Lezardrieux takes place every Friday morning throughout the year. Stalls include, among other things, fruit and vegetables, fish and shellfish, meat, flowers and plants, and clothing. The market adds a regular weekly event in town to the activities along the river. If you are planning your trip around a particular day of the week, Friday morning is the time to keep in mind.
