When the crowds of summer fade and the snowflakes are still weeks away, Sun Valley transforms into one of the most magical fall destinations in the Rockies.
Crisp mountain air, golden aspen groves, and slower rhythms make fall in Sun Valley a season you don’t want to miss.
Here’s your guide to the best of September and October in Sun Valley, Idaho.
As the days shorten, the leaves start their show – color changes begin at higher elevations in mid-September and peak in mid-October, painting the valley in shades of gold. Fall is the locals’ season – uncrowded golden trails for hiking, biking, and horse riding, pristine rivers for fly fishing, easier restaurant reservations, and slower-season pricing on vacation rentals – the perfect excuse to splurge on fall getaway to Sun Valley.
Highlight of the Season: Trailing of the Sheep 2025
October 8-12
Every fall, as the leaves turn golden and the crisp mountain air rolls in, the Wood River Valley welcomes back one of its most cherished traditions – the Annual Trailing of the Sheep Festival and the unforgettable sight of more than 1,500 sheep parading right down Ketchum’s Main Street. What began as a way for local ranchers to move their flocks from summer pastures to winter grazing grounds has gained recognition by USA Today, National Geographic, and msn.com as one of the Best Fall Festivals in the US,
