(work in progress)
As you will have gathered by now, I liked pretty well everything about Guerlesquin: it really is a delightful little town that is heartwarmingly accessible to visitors, without having 'sold out' to the tourist hoardes.
One small but significant contributing factor to this congenial atmosphere is the excellent signage for visitors, which features not only French, but also English narrative. It's a small investment to make, and yet makes such a difference to making visitors feel welcomed - bravo!
Favorite thing: Almost every corner of the village is embellished with a lot of flowers. Moreover, there is a nice park with a fountain near Saint-Ténénan, which you can see in the last photo of this tip.
