At Toul Colo (cross and old transformer covered in ivy), turn right at the sign for Chapelle Saint-Pierre. The small car park is located just at the end of the road.
Parking near the Chapelle Saint-Pierre.
YellowPR® route Saint-Pierre markings (not very visible).
(S/E) With your back to the small car park, head north-east along the wide farm track that descends towards a stream and then climbs back up towards the house at Roz ar Veil. Continue along the road and at the crossroads (Kergoat Nevet sign), turn right for about 100 metres.
(1) Turn left onto a wide path that climbs and offers a wide panorama to the west. Continue to a fork (entrance to a field on the right).
(2) Turn left onto a small path, pass under a power line and continue along this sunken path lined with old chestnut and beech trees. You will come out facing a stream.
(3) Cross, turn right and climb steadily along the edge of the woods. The path veers left and then runs alongside the road leading to a car park. Continue straight ahead, leaving the car park on your left. Go through a gate, take the wide forest lane Hent Kreiz and pass the forest house.
Mountain bike signposting.
(4) At the Pen ar C'hoad signpost, turn right and then right again at the three-way junction (not visible on the map) and join the edge of the woods marked by a wire fence. Continue with the fence on your right.
GR® 38 white and red markings.
(5) At Plas ar Lochou (on the map), join theGR® which veers to the left. Continue, ignoring all the paths leading off to the left.
Pass a path marked for people with reduced mobility on your left and you will come to a barrier marking the boundary of a car park.
Off the marked trail
(6) At the car park exit, turn left, follow the road and you will come to the gate of the Koat Ar Gazek Glaz estate (Bois de la Jument Verte). At the sign for "Coz-Castel, 2.5km", leave the road, turn left and follow the estate fence.
(7) At the signpost marking the northern boundary of the estate, turn right and continue to follow the fence on your right. Reach the wide forest path Hent Kreiz and take it to the left for about a hundred metres until you reach the crossroads of forest paths.
(8) At the Hent Treuz/Hent Kreiz crossroads, turn right into the forest lane (bench) and continue straight ahead on this wide lane until you reach another forest lane, Hent ar Stankou, which you take on the left. Follow this beautiful lane towards the lake (Stang ar Bleïz on the map) without going all the way to the pond.
YellowPR® Saint-Pierre route markings (not very visible).
(9) At the start of the climb, turn right, leaving the main lane to enter the woods.
The path winds its way between the trees and descends towards a lake that can be seen below. Go down and go around it on the right. Turn left and cross a footbridge over the stream that flows into the pond. Pass through a cleared area, follow the wide path marked out for this work (10/2019) and arrive at a signpost marked: Chapelle 2.5km. Further on, the path joins a wire fence marking the boundary of the Névet manor house, which is not visible. The path runs alongside the wire fence on the right-hand side until it reaches a small clearing extending into a valley.
(10) At the signpost, turn left, leaving the wire fence, and follow a wide grassy path towards a farm building that gradually comes into view.
Shortly before this building, thePR® turns sharply to the right.
(11) Climb into the woods and continue straight ahead. At the next signpost, turn left and continue climbing until you reach a beautiful grassy path.
(12) Turn right to begin a pleasant descent to a crossroads. Descend towards the stream and its footbridge, then climb back up to enter the grounds of the Chapelle Saint-Pierre on your left and return to the car park where you started (S/E).
