Large car park near the old train station of Plouescat / Rosporden. This circuit is shaped like a number 8. Unbeatable views towards the southern slopes of the Arrée Mountains, passing near the drinking-water reservoir in Brennilis, followed by Kerelcun and its magnificent restored mill. After crossing the Lorient-Roscoff axis at Coat Mocun bridge, this old Roman Road will lead you to the springs of Roudoudour and the mystical mashlands of Yeun Elez. In Kervéguénet, visit the museum of Youdig, a miniature village from the 16th century, with gites and an inn. Finally, you can head back to Brennilis, where you began.
