We do use the M6 toll, it is quiet and free running. If you are CC members show your membership card and they only charge you as a car, but you have to go to a manned booth.
I wouldn't go on the M1 and then up to Junction 25. You will then have to cross Derby and there are road works on the ring road. From the M6 toll stay on the A38 towards Derby, (Lichfield and Burton on Trent) then as you get closer to Derby continue to follow the signs for "A38 The North". You will come to one big roundabout, (it doesn't look like a roundabout from where you join it), you will just stay to the left. Stay on the A38 North to the next island (Markeaton Island) There is a McDonalds on your left and an Esso petrol station, Turn left here onto the A52 to Ashbourne and follow the signs to Ashbourne and then through Ashbourne to Fenny Bentley. This will take you up to Rivendale which will be on your right. Derby is local to me. If you want us to talk you through it, get my email off Parksy and I will send you my phone number.
We will be passing you going the other way as we are off to Woolacombe!
