Unique in France, this circuit featuring many varieties of Brittany’s symbolic plant, the hydrangea, takes you on a walk round the Lac au Duc.
The trail starts in the fantastic undergrowth by the Lac au Duc, and continues on for some 3 kilometres. From the beginning of July through to the end of September, the lake blossoms with colourful and majestic flowers, pink, red, blue and white. Narrated walks are organised twice weekly, not just to explain some of the history of these symbolic plants (originally from Asia and imported to Brittany), but also to offer advice on how to grow them. The hortensia trail is the result of a collaboration between Ploërmel local council and Alain Dussine, a keen nurseryman, and today the collection is unique in Europe. Opened in 2000, the trail has 5500 hortensias, with around 550 different varieties!
