How hard is it to drive the Needles Highway?
How hard is it to drive the Needles Highway? As Needles Highway is only 14 miles long, you can most certainly drive all of it in less than an hour. With that said, due to its one-way tunnels, tight turns, and slow driving sightseers it can be a bit slow going. To avoid max traffic congestion, drive Needles Highway in the Spring or Fall.
