I believe with the recent changes to federal legislation regarding user fee areas, the requirement for a $7 daily pass to park at the trailhead no longer applies. There were no signs at the trailhead mentioning "Fee Area" or "Parking Pass Required." A call to the ranger district in Sun Valley/Ketchum may be in order to verify but that was my experience on July 31, 2005.
Thanks for the heads-up guys. I have fixed the red tape section.
The driving directions seem a bit outdated and kind of confused me in getting there. The mileage was a bit off and there have been some changes since it was written. Here's my description edited from the original.
At five miles south from Ketchum on Idaho state highway 75 turn east onto East Fork Road. Drive 4.5 miles east and you will come to an old mining town called Triumph. 1 mile past Triumph turn left turn on an unmarked well maintained dirt road. Drive another 4.5 miles to the trailhead at the North Fork of Hyndman Creek. There is parking and a toilet facility.
Follow the old road from the trail head is a bit vague and if you do that you go on the wrong trail. Pleas follow the sign showing trail 166.
