The McCall airport is neither short, nor a 'backcountry' strip, but it is one of the most popular stops before heading into many of Idaho's popular backcountry strips. McCall is a great town with all the gear/supplies/services that you'll need before heading into the backcountry.
It's also a great vacation spot with access to an abundance of recreational activities.
The strip is long, paved, and the conditions are fairly predictable.
