From Roscoff, go to Morlaix and take the N12 to Rennes (approximately 2.5 hrs) arriving onto the N136 around Rennes.

Take the exit for Nantes, N137, and about 20 mins south of Rennes, take the exit for Derval (next one after Grand Fougeray). Follow directions into Derval centre, and turn right to Guémené Penfao D775. This is a straighter route but 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 Avessac to your right and Plessé to your left. Take the left towards Plessé D131, and after 2 or 3 minutes you come to a crossroads with your 'STOP'.

At this crossroads turn right towards Fégréac D124 (left is Guémené, straight on is Plessé) and take the second exit on your left (small crossroads) marked La Roche Buttée with a new chalet on the corner. Go to the top of the lane and on the first bend is us. Take the driveway to the right-hand-side of the house.
