From the South Entrance of Yellowstone to the Moran entrance to Grand Teton is about 45 miles and about an hour. However, it is about 15 minutes to the entrance to Grand Teton, but it takes a while longer to get to Jackson Lake, Leeks Marina and around the corner to Colter Bay with its general store, grocery store, restaurants and marina where you can get a cruise on the lake for a wondrous trip. We go to Colter Bay, usually three times each summer to fish Jackson and sightsee both Grand Teton and Yellowstone. If a person were to stay at Colter Bay, it's about 45 minutes to the South entrance to Yellowstone so we just get up a little earlier than usual and drive to Yellowstone for the day. Usually see a lot of what we want and then get back to our Fifth Wheel for a late dinner. I know most of the folks say that Yellowstone is too big to take a trip that way, but it works for us as the Colter Bay campground is a very nice place to stay while we fish the lake.
