There are actually three choices for crossing the Bighorns. All three are less difficult eastbound than westbound.
Hwy. 16 is an easier drive, but IMO, hwy 14 is more scenic. If you do choose hwy. 14, be sure to stop an see the falls at the Shell Canyon visitor center.
My favorite route is hwy.14A. If you go that way, stop and visit Bighorn Canyon National Recreation Area just east of Lovell. The scenery is spectacular and the campground is free. Bighorn sheep and wild horses can usually be found wandering along the roads.
