Falls Campground near the South Fork of the Snake River feels like North Idaho or the West Cascades more than eastern Idaho. The South Fork's dense cottonwood forest feels like a jungle with its tall, broad-canopied trees and lush underbrush. The campground is near Palisades Reservoir on the Wyoming border, but it is a fairly easy six-hour drive because it is mostly freeway driving.
