Sun Valley
One of the first purpose-built ski resorts in the country still drawing the same devoted crowd, hot springs scattered through the mountains for after the last run, and a valley quiet enough in summer that the wildlife barely registers you are there.
The best time to visit Sun Valley is Dec–Mar, or Jun–Sep, when typical daytime highs reach about 25°C (77°F).
