You need to go very very slow in some places. The gravel road in certain areas has deep holes/bumps which even an SUV can't drive over fast. Be aware of your clearance. You can try to pass them from the edge but still, chances are, two tires will be on those bumps/holes. It's quite bad but doable.
It's gravel the whole way. Watch out for pedestrian crossing at the Rocky Mountain Mennonite Camp.
You should be ok as long as the weather's nice! Rain or snow and you might have problems
