Most of all it is located in the high and wild Gros Ventre Range, which is incredibly rugged and beautiful. It is in prime wildlife habitat, with elk, deer, moose, bears, lions and most other mammals found in this part of Wyoming.
One side of the mountain drains into the lovely and aptly named Swift Creek. It is also on the divide between Granite and Crystal Creeks, two incredible watersheds.
Supposedly named because of the French trappers who were once here, the name is an elegant compliment to the fine lines on this majestic peak. When you first begin the drive on the Granite Hot Springs road, a lovely pyramid of a peak stands on the skyline in front of you. This is the great Antoinette, standing tall in the middle of a great wilderness. The road makes access easy in the summer, but it still is a good hike to the summit. The Swift Creek Trail is a no nonsense trail that gets you up into the high country quickly. It is a beautiful hike from a lovely forest, up to timberline, then above to the divide.
From highway 191 in the Hoback Canyon, turn left at the intersection for Granite Hot Springs. Follow the road for close to nine miles, turning right at the second bridge over Granite Creek. Look for the Safari Club sign, and trailhead parking. There is a sign with information in the parking area describing the Wilderness area, and small sign pointing to the Swift Creek trail.
A mile past the turnoff is the developed campground. If you continue almost to the end of the road, there is an incredible place to view Granite Falls. When it is high water, these falls are huge and roaring, well worth a look.
At roads end, is Granite Hot Springs, a hot sulfur pool, for a small charge, a great place to relax.
Below the falls is a small hot spring across the river which can be accessed from the other side. Look for the small rock walls, and sometimes people sitting in it.
There are some excellent backcountry possibilites on the hike up. I have camped a little way below the divide, there are nice clumps of trees for protection and some little springs around most of the year for water.
