I didn't mean to say Port Hardy is difficult or dangerous. Maybe I should have said, interesting or scenic.
I've to Port Hardy twice - once on the way to Cape Scott (with overnight hike to San Josef Bay), and once on the way to Prince Rupert and QCI. And part of the way much earlier to Zeballos. Sure it's paved and all that, but anything beyond Campbell River is getting away from civilization.
So you are driving into Bella Coola as well as driving out? In any case I think the drive down requires more care than the drive up.
I drove it in an SUV so had no problems either way. Going down, they were doing some road work, and had just applied dust suppressant. That left out wheel wells coated with a mud that never dried. Fortunately the campground host (at Gnomes Home) let use his hose to wash most of it off.
The Bella Coola area is most fun in a vehicle that lets you drive the backroads, such as the one to Odegaard Falls.
