"Not only is autumn Jackson Hole’s best-kept secret, but it’s also one of the best times to check out Grand Teton National Park. The aspen and cottonwood trees turn bright yellow and gold, making for a stunning contrast to the Teton Range in the distance, and the hoards of travelers trying to find parking around Jenny Lake disperse. Plus, wildlife tours can be extra exciting as the elk rut takes place from mid-September through October, and bears make an appearance as they get ready to go into hibernation." - Travel + Leisure Editors
