"In the fall I find Grand Teton National Park shines with golden aspens and dramatic peaks and feels like a welcome break from summer crowds. It's ideal for hiking scenic trails, floating the Snake River, and stargazing under some of the darkest skies in the U.S. I recommend visiting early in the fall to avoid seasonal closures, since leaf-peeping draws travelers." - Stephanie Vermillion Stephanie Vermillion Stephanie Vermillion is a travel journalist and photographer covering culture and adventure for Travel + Leisure Outside, and more.
