Give Mountain Air a ring.
Called the Chateau Strip.
Quite long, around 900m but one way (power lines at SE end) and I think about 2% slope. 33 and 15 from memory. Mountain traffic 119.6.
If it's not covered in snow can be hard early morning and late arvo with frozen ground. I think there is a sealed pad now at the top by the road thus eliminating the muddiest areas.
Don't know if it's in the AIP.
