A fantastic route! Murat is a lovely town and the first part of the ride from there to the Puy Mary is very pleasant.Once at the summit the views are breathtaking, there's also a nice cafe that's worth stopping off at.
After refreshment continue down the other side in to the valley and on to Salers,one of Frances most beautiful villages famous for it's breed of cattle who's milk produces the regional cheese of the same name.
It's a great ride there and back. Would highly recommend it if you're in the area.
Another of my favorite roads in this area.
Race track smoothness and corners in places.
A group of us visit Vichy and ride this road at least once a year.
It can be very, very fast if you feel the need. Nice cafe in Ambert on the right as you get to the lights.
See D906/907 from Ambert as well.
