Horses, from the West side
The horse packers we talked to in Pinedale a few years ago said they "might" be able to carry kayaks on pack horses all the way up the Titcomb Lakes trail from the end of the Fremont Lake road. That would be the meeting point with the outfitter. The one guy who gave us the most info said we'd probably have to hoof it ourselves over Bonney Pass between Gannett Peak and Mt. Warren. About 1 1/2 miles of serious uphill, then all mostly downhill to the upper N. Fork, around 3 1/2 to 4 miles. Lots of rocks, not much chance to drag boats. Price was $350 per pack horse, no riding.
It's not a bad way to go. We've done the upper South Fork Shoshone that way twice, leading horses carrying two kayaks all the way in to the put-in, around 15 miles in. The outfitter lived in Dubois, WY. I carried my paddle and led a horse, that was it. Well worth the dinero to save the back. That was $200 a horse, and we paid for two extra horses to carry our soft gear.
