Sun Valley is not just a great resort town, it's a beautiful area.
Down the road is Silver Creek. It's not just a creek; it's a whole valley of spring creeks--like Loving Creek here.
If you come in the summer, rent a crossover and drive up Trail Creek Road for splendid views and a little excitement.
Then head over to Copper Basinand make a loop out of it. Drive over the Burma Road for an eagle's eye view of the Big Lost River Valley and Mt. Borah, the highest peak in Idaho.
