 The route also takes the riders near several wilderness areas, including the Hemingway-Boulder, the Sawtooth, the Frank Church River of No Return, and the Cecil D. Andrus–White Clouds Wilderness, which effectively bars cyclists from the White Cloud singletrack option.Most people ride the route counterclockwise with typical times to complete it ranging from 2 to 3 weeks.Due to the mountainous terrain and the unpredictable central Idaho weather, the riding season generally runs from May after the roads are free of snow to October when the snow flies again.
