Towing Route Advice Saint Malo to Quimper

I don’t know the road numbers but would go via St Brieuc, Carhaix Plouguer and Chateaulin -  but as they are all by passed you need not actually go into any of those towns. That road is good and is traffic and tourist free.

Thanks.  The route you suggest is option 1 above.  Can you recommend a good place to stop for a short break on route? Thanks

Either route will be fine, easy driving  and enjoyable. Plenty of places to stop off so just go with the flow and have a great time.

I agree with Jamsdad - just  stop if you feel the need.or if you see a picnic area.   But if you want diesel, petrol, recharge electric car, groceries, beer, wine, lunch or toilets, then there is an easy access Intermarche Hyper at Rostrenen - about 90 miles along your route.
