The other consideration is JAC is the largest airport

in the area, plus Jacksonhole itself has much more vacation facilities, such as rental car companies at the airport.

The ranger station right at the entrance of the town of Jacksonhole has some excellent exhibits of wildlife and introduction of the park. Those Elk horns arches at the town center park are quite a sight too.

I cannot imagine anyone going to visit YS and would not visit Grand Teton - in fact, to some people, the hiking in Grand Teton, is more scenie than YS which is more for the wildlife and the geysers.

Grand Teton directly leads in the South Entrance of YS.
