Parking available at the Tourist Office in Saint-Nicolas des Eaux
(S/E) Retrace your steps and cross the D1, leaving the road bridge on your right.
Take the towpath on the left bank, which follows the meander of the Blavet to the Casternec site.
Walk along the towpath, noting the beautiful old trees (oaks, plane trees, beeches) that line the path. Pass the marshy area in the bend on your right (an area frequented by herons).
(1) You will reach the first lock, La Couarde.
Continue on and, on the cliff on your left, notice the iron bird sculptures attached to the rock.
(2) Pass under the Pontivy–Auray railway bridge, which is still in use for a few freight trains.
(3) You will soon arrive opposite the site of the Saint-Gildas chapel-hermitage on the opposite bank (unobstructed view of the site).
(4) Pass the second lock, Gamblen, and note a break in the vegetation on the opposite bank: crops give way to wooded areas. Looking back, you can see the bell tower of Bieuzy-les-Eaux.
(5) You will reach an area where you can see private ponds on the left. Continue past the lodges and caravan rentals at Lost ar Lann and you will reach the last and largest lock, Moulin Neuf, which is the end of the outward journey.

(7) Leave the road leading to the Lost er Lann lodges on your left and continue straight ahead along a path until you reach a road.
(8) Turn left onto the towpath (barrier).
