The easiest way to get to the park is by flying into Jackson Hole Airport, which is actually inside the park (it’s the only airport that’s located in a national park). Jackson Hole is well connected to the rest of the country, although many flights only operate during the summer. If you’ve got the time, another option is to drive to Grand Teton via Yellowstone National Park. The two parks are only separated by the 27-mile-long John D. Rockefeller, Jr. Memorial Parkway. This allows you to fly into Bozeman, Montana, which has more year-round options and is also less expensive than Jackson.
