Two weeks ago in SW Wyoming, access from Driggs, ID, Targhee National Forest, Teton Creek, South Fork, 2.5 hours on trail in canyon. Cool in early to mid AM, no people, dense colorful widflowers this summer chest high in all clearings. Highly recommended. After the run a swim in the "cool" creek was just the thing.
Plenty of parking, good access and plentiful camping with clean RR, est. $10 per night.
