Grand Tetons Gros Ventre Campground often isn't full, but only a limited number of sites with electricity. Being in Victor, you either have to drive north to West Yellowstone, use U.S. 26 to go E and south to come up to Jackson from the south, OR use Teton Pass. That route has 10% grades up and down and is not for the faint of heart.
