I parked my truck at 850m . It's a steep cutblock road with medium cross ditches installed but went fine for my stock toyota pickup. Anything with some all terrain tires and abit of clearance and maybe 4x4 because of the grade should be able to drive it. I used this for access for Noroche Mountain and got to the top in 2hrs 20min. Personally I would probably consider going this way for Deroche Mountain to bypass the shitty alder road approach.
