Leaving St Malo, follow directions for Rennes N137, arriving there in approximately 40 minutes.

At Rennes take the ring road N136 round Rennes for Nantes, then the N137 again towards Nantes.

About 20 mins south of Rennes, take the exit for Derval (next one after Grand Fougeray). You can either take the more direct route following directions into Derval centre, and turn right to Guémené Penfao along the D775, or you could take the directions for Guémené from the dual carriageway turn off, which is rural and pretty.

At Guémené, take the D775 straight on towards Redon, for about 7-8 mins, until you come to La Ville en Pierre (halfway to Redon). This is a crossroads with a war memorial on the far left corner, and a restaurant on the right hand side. The village of Avessac is sign posted to your right and Plessé to your left. Take the D131 left to Plessé, and after 2 or 3 minutes you come to a crossroads with a ‘STOP’ sign against you.

At this crossroads turn right towards Fégréac along the D124 (left is to Guémené, straight on is to Plessé). After a couple of minutes (1 mile), take the second exit on your left (small crossroads) marked La Roche Buttée, with a new chalet on the corner. Continue up the lane until it bears sharp right along the frontage of La Petite Ferme. Take the driveway to the right-hand-side of the house.
