Crested Butte isn't called the Wildflower Capital of Colorado for nothing. When it's not digging gold out of skiers' wallets, the old mining town banks on other colors. In the summer, the valley and mountainsides are a riot of wildflowers, a sight so spectacular that it inspired the Crested Butte Wildflower Festival, a week-long celebration of petal power. This year's event, set for July 7 through 13, features classes where you can draw wildflowers, photograph them and cook with them; on various tours, you can see wildflowers while walking, biking, jeeping or riding on horseback. You'll spot everything from the mainstream mule's ear to wisps of prairie smoke — but the king of the hill is the columbine, Colorado's state flower, in hues ranging from pale pink to yellow to blue to deep purple. Look, but don't pick.
