My husband and I have driven the Alcan highway seven times. We drove the highway in summer, fall and in winter. Driving in the winter on the Alcan Highway isn't the best time to travel, as temps can drop down below -60 and colder.
Each time traveling the Alcan highway, has been a great time!
Give it a try! Plan to at least take seven days to travel the Alcan. It's an experience you won't forget!
