How are the roads

I guess it all depends on where you are coming from and the type of roads you are use to. If roads without curves is what you always drive then it's going to be a dangerous road to you if you are then it won't bother you at all.

There's a couple different routes you can take to get there depending on which one you take will determine how curvy the roads will be. However regardless of the route you choose there will be some curvy areas & generally all the routes are dark in the mountains at night. I'd recommend driving there the first time while there's still light out :)

Well traveled and safe. Good luck.
