One of the first excursions Idaho locals recommend to newcomers is the Ponderosa Pine Scenic Byway along Highway 21 from Boise to Stanley, Idaho. The popular route traverses foothills, high-elevation forests and scenic river canyons in the heart of the Boise National Forest and Sawtooth National Recreation Area.
Although beautiful in any season, fall is my favorite time of year for exploring Highway 21. The combination of sunny, cool days melding into together with cold-but-not-freezing nights help intensify the forest’s autumn hues. Color is often good in September but generally peaks in in early to mid-October, depending on elevation.
