Treffiagat offers a variety of reasons to stay: prehistoric megaliths, the architecture of Chapelle Saint-Fiacre, birdwatching at Étang de Lehan, a walkable stretch of dunes and the marina at Port de Léchiagat. The highlights range from cultural heritage sites to nature observation and water sports. When planning your trip, you can decide which is most important to you.

Megaliths: individual menhirs and a complex

Menhir de Lehan is a Neolithic megalith dating from around 3000 BC. It stands in a pond and is 8.50 metres high. It was listed as a historic monument on 6 March 1923. The approximate dating places it in prehistoric times; the exact date refers to its later protected status.

Menhir du Reun is six metres high and six metres wide and is also classified as a historic monument. In a direct comparison of their heights, Lehan, at 8.50 metres, is 2.50 metres taller. A width is also given for Menhir du Reun. These measurements help distinguish the two individual monuments.

By contrast, the site du Reun centres on a megalithic complex. It includes the remains of a destroyed tumulus; the rocks also bear prehistoric engravings and cup marks. So this is not just about the dimensions of a single upright stone, but also about remains and traces of rock carving. Visitors interested in prehistoric evidence will find different forms here that can be considered separately.

Chapelle Saint-Fiacre: architecture and traces of time

Chapelle Saint-Fiacre dates from the 16th century, is designed in the Flamboyant Gothic style and has been restored several times. Inside, the panelled ceiling resembles the hull of a ship. This distinctive ceiling motif adds a specific detail of the interior to the broader context of its period and style.

A spring fed by an underground stream is located in the choir wall. It dates from the 15th century, making it older than the chapel. This gives two different points of reference for the historical context: the spring and the chapel, with its 16th-century architecture. The stream also explains where the spring water comes from.

Birdwatching, dunes and harbour

At Étang de Lehan, you can see grey herons, and there is a birdwatching station and an educational trail. The grey herons are a specific feature of the local birdlife; the station and trail add opportunities for observation and learning about nature. For travellers interested in birds, the Étang offers a clear focus that goes beyond a general description of the landscape.

You can walk along Treffiagat’s stretch of dunes via the GR34, the Sentier des Douaniers. This offers a different focus from birdwatching at the Étang: here, walking across the dunes takes centre stage. When planning, you can choose between nature observation and a walk along the GR34 without assuming a fixed order for visiting the sites.

The marina at Port de Léchiagat adds a water-sports dimension to these attractions. Its mooring area has just under 298 berths, as well as a pontoon for short stays and services for water-sports enthusiasts. The number refers to berths in the mooring area; the pontoon and services are additional, distinct features of the harbour. Those who make water sports the focus of their stay will find a different option here from the cultural heritage sites, the chapel or the stretch of dunes.
