Answer: Depends on the road conditions. I live in Jackson so traveling to school and then home on vacations and sometimes long weekends always varies. On dry roads it will take about 6 hours going from Laramie to Rock Springs (Interstate) and then from Rock Springs to Jackson. However when Elk Mountain is bad...it can take up to 8 hours. Just because of the deteriorated conditions.
Answer: The driving distance from Casper, Wyoming to Jackson Hole, Wyoming is about 288 miles. The amount of time without stops it would take would be somewhere around 5 hours and 45 minutes. About two hours of the trip has a maximum speed limit of 55, and the rest 65. There are many small towns en route where one must slow down. There is a 9000 foot mountain pass en route, where speeds are often slower, specially if there is construction (expect for several more summers) or if there is weather (a common occurrence). Google WYDOT to check on road conditions.
