Tips from the Community

Fabrice Rigalleau
April 15, 2026, Manoir du Grand Trémaudan

Partially dating from the 15th and 16th centuries, it was remodeled in the early 17th century, as evidenced by the date 1630 engraved on a dormer window. This monument illustrates the architectural evolution of Breton seigneurial residences, blending medieval elements with additions from the classical period.

The abbey church and cloister are definitely worth a visit.

Cornice path running along the outer rampart of the castle. Use with caution!

excellent little circuit in the undergrowth, in the middle of several others allowing you to link them together.

Caution: The road slopes steeply after the manor. A dirt road 100m after the manor, heading uphill, is very technical (ruts, scree), and climbs for 500m. The ascent is long and difficult, but the descent is also fast and dangerous (60 km/h on a mountain bike if you stay on the road, much slower if you follow the path).

Lots of roots, but it's worth shaking as it's so beautiful, surrounded by water.
