Drive north on I-15 from Salt Lake City. Take exit 362 Brigham City, and follow US 89/91 through the mountains unofficially referred to as Sardine Canyon into Cache Valley. The drive should take about 75-90 minutes. US 89 and 91 split in downtown Logan. US 89 heads east through the beautiful Logan Canyon to Bear Lake, a popular tourist destination, while US 91 heads north into Idaho. A regional airport also serves Logan although no commercial commuter flights are available at this time.Alternately you can also take I-15 N and take Exit 351 for Willard. The short UT126 section branches off towards US-89 for Logan and Ogden. Keep left at that fork and follow the road till you reach Brigham City and then the right lane will lead you towards Logan. This route is 7 miles shorter and a more comfortable drive with very little traffic.
