best route from Ogden/salt lake to Grand Teton/Jackson?

I-15 north to Idaho Falls. US-26 east/southeast/north to Jackson and Grand Teton National Park, Wyoming. This completely avoids any mountain passes, but is still a beautiful drive.

Ok, Thanks. Saw a lot of construction on Google for that and had considered the 30.

I would not go the extra 45 miles to ID falls and then 26 to avoid one 6800' pass on 30/34 to 89 and 26. If you go 26, do not even think about using 20 into Jackson at Swan Valley, take 26 all of the way around.

Ok thanks. I believe I did that pass 10 yrs ago towing a 5er toy hauler. Seemed tight..but moving.

I would agree. Seems a longer route than the 30/34 noted, but I'm not familiar with 30/34, so couldn't recommend it. I-15 to Idaho Falls, then US 26 to Alpine Junction, then 26/89 to Hoback and Jackson, is really uneventful as far as passes and it's still scenic. We take that route all the time from our house near Boise. At Palisades is a park with hookups at the base of the dam should you decide to stop. It's a good overnight stop, and easy in and easy out. At Alpine is a Chevron roomy enough for you to pull through and fill up. They put in a round about at Hoback so you'll have to maneuver around that. Most definitely do not take Teton Pass Hwy 22 between Victor and Jackson. Not worth it.

We also recommend Hwy 26 - almost flat but a beautiful drive.

Did this route last year and went thru Logan, Utah. Avoid Logan at all costs, grades were fine, Logan is just a pita to drive thru. Also did hwy 26 and it was fine.

I just did US26 out of Idaho Falls. That is the one I'd recommend. A very scenic route right along the Snake River and a breeze drive wise.

Pulled 30,34 and 89 in. Easy peasy.

Good to know! Thanks for the feedback especially on 30/34.
