West Coast Mountains

Yup they are big and worst part is they can be long too which is most often times worse then steepness.

 

I agree with @Roberts450 Also going up them is usually not the problem, it’s the backside that gets sketchy.

 

Be afraid. Be very adraid.

Donner pass i80 between CA and Nevada is 40 miles of downgrade.

 

I only drive through the NW mountains, and in my opinion the worst climb isn't even a mountain, its climbing back out out of the Columbia river on 90 west bound. Those are no worse then driving through the bigger Appalachian mountains.

 

It's not the climb that gets you in trouble

 

Hwy 58 in Oregon is no joke. There are a few others.

 

The western 11 states is all I drive, and they aren't bad at all. You get really good at downshifting before grades and using your jakes. The steepest and longest one coming and going I can think of is I-70 coming into Denver from the west out of Vale. I've seen lots of burning brakes and trailers on that grade.

I grew up in the Midwest and live on the west coast. A lot more fun driving out here as far as I'm concerned
