US-89 is Your Ticket then

By all means then, try US-89. I have driven it and I think it will suit your needs. Along the way you'll be driving through Cache National Forest, along the shores of Bear Lake, down the Star Valley of Wyoming, and along part of the Wyoming Centennial Scenic Byway through Jackson Hole on your way to Grand Teton National Park - all before reaching Yellowstone.
If you find that, after taking that drive north, you still want a different road south, I'd recommend that you try this. Leave Yellowstone to the west on US-20 and go as far as Idaho Falls. Here, pick up US-91 south. This will occasionally share alignment with I-15, but in most cases, the old non-motorway US-91 will still be there, marked as Business-91 or Business-15. US-91 will eventually return you to Logan, UT where you would join US-89 for the remainder of the way back to Salt lake City.
