Hiking the easy half-mile Flaming Rock Trail in Idaho's City of Rocks National Reserve, my family spies a wall of tortured faces that echo the elongated mask of the Scream movies. Undaunted, the kids scramble over some of the most bodacious boulders they'll ever see; me, I just savor the crisp fall air.
We're not the first visitors to have our imaginations piqued: Back in the 1840s, California Trail pioneers stumbled upon the hundreds of towering rock formations, "some resembling cottages, others steeples and domes ... it is a sublime, strange, and wonderful scene," wrote pioneer Margaret Frink.
Visit this month and the formations still enchant, but the season throws in a bonus: The autumn glow of tinted aspen and cottonwood trees.
