Drystock2, I presently live in San Jose, but my home town is Sonora and I have to disagree with Willyslover comment about Tioga being the worst. The worst pass is Sonora Pass. It has at least two sets of switch backs and the road is very narrow, barely two cars wide. The worst double switch back (like a "S")is on the west side just after Chipmunk Flat, the first part of it you can see the traffic coming, but the second part is around a blind corner going to the left just as you head up an even more steeper grade alongside Deadman Creek. Even with a 24 foot trailer you will have to take the entire corner and just hope no one is coming down from the other direction. If someone is coming, the grade is a least 8 - 9 % and they will have a difficult time stopping in time. The other impressive corner in on the east side at the bottom of a long down grade going into Levitt Meadow. In short, do not take a trailer over Sonora Pass the first time you drive over it.
Tioga Pass road on the east side as I said in my previous message is steep, but the road is wide, good visibility, with long straight and sweeping corners.
For your knowledge I have driven over all of the Sierra passes except I haven't taken my trailer or will I ever take it over Sonora Pass.
Over the last forty years, I guess I have driven over Sonora Pass at least 50 times. Probably the most fun time was when I was coming back from Hot August Nites in my 66 Dodge GT Dart, 340 cu in, 4 speed charging up the east side. What a blast especially turning it loose going up the last steep section just before the top. It is nearly straight up after crossing over a short bridge in a gully leading into a slow corner going to the left, then straight up the side of the mountain to the top. Can you imagine being near 10,000 feet, pulling 3rd gear around 60 mph and can not obtain anymore speed because both rear tires are spinning.
Don't get me wrong I wasn't driving recklessly, I shut it down well before I got to the top. I know Sonora Pass like the back of my hand.
Well, in short knowing Sonora Pass, I would not attempt it or even suggest to anyone taking a 24 foot or longer trailer over this pass because of the narrowest, switch back blind corners.
In closing, here is my 2 cents for rating the sierra passes starting with the easiest (1) to the most difficult (6).
1. Donner Pass (hiway 80)
2. Echo Pass (hiway 50)
3. Carson Pass (hiway 88) my favorite for scenery
4. Ebbits Pass (hiway 4) road barely two cars wide and a lot of tight corners, but not real steep.
5. Tioga Pass (hiway 120)
6. Sonora Pass (hiway 108)
