Parking is available on the village green, in front of the main façade of Tonquédec Church.
(S/E) Facing the church, leave the village green on the left via the Route du Château.
After 100m, turn right onto Rue de la Fontaine Saint-Gildas.
At the bend, continue straight ahead along the path, then keep left at the fork. The path leads onto Route du Château at a crossroads (D113).
(1) Cross straight ahead and immediately take a path on the left.Be careful, asit is barely visible and requires you to cross the ditch and then the embankment. It runs alongside the D113 for a few metres before veering away from it; furthermore, it does not appear on maps.
The path crosses a stream (barely visible in summer) several times before joining a track to follow on the left.
Then, after 100m, take a farm track to the right and, at the end of it, turn left. This track crosses Kergastel and leads to Kerbabu.
(2) At Kerbabu, turn right towards Penn ar Guer then continue along the path
(3) Take a path on the left that is not shown on maps. It becomes a track, then takes a sharp left-hand bend. At this bend, take the track on the right, heading west then south-west, before reaching the road to Kerrivoalan. Turn right towards the chapel.
(4) Continue along this track, which becomes a path as it climbs. Pass under a high-voltage power line and, once on the track, turn left. The track makes a U-turn to the right to run alongside the Léguer, which you must cross at Kergrist Mill by taking the two footbridges.
(5) Continue along this path, which climbs and ends at the entrance to Kergrist Castle.
(6) Leave the castle gates behind you and take the main driveway. After a slight bend to the left, take a small path on the right (hard to see as there are logs along the path). When you reach Kernalegenn, turn right.
(7) Continue along the road to the right and follow it as it curves to the left. Ignore a farm track on the right and, at the crossroads, turn right and continue along this rather winding road.
(8) Turn right and follow the forest path, which is not shown on maps. Cross the D113 and continue along the path directly opposite; it makes a wide U-turn to the right to run alongside the D113.
(9) Turn left to cross the bridge. On the left, amongst the trees, you can see the ruins of the tower of Tonquédec Castle. Continue along the road; there is a footpath on the left-hand verge.
(10) Pass the entrance to Tonquédec Castle on your left (private property) and continue along the road. After 300 m, look out for a hairpin bend on the left. Take this and head northwards. It climbs quite steeply to a road. At the crossroads, turn right and reach a road.
Turn right. Follow this road to the crossroads.
(11) At the wayside cross, turn right. Return to the crossroads (1) and follow the same route as on the way out. Before the stop sign at the D113, take the path on the left. At the Fork in the road, turn right and continue straight on along the road. Join the D113 to return to the car park on the village green (S/E).
