They have done some major work on the road to Capitol Creek Trailhead. I saw a Prius at the trailhead yesterday. We have a truck with good clearance and 4 wheel low and we were able to continue 1.2 miles past Capital Creek to the Hell Roaring Trailhead. I WOULD NOT ATTEMPT THIS WITHOUT 4 WHEEL LOW AND SOME SERIOUS TIRES! It has some incredibly steep grades and without the right gearing you could get stuck and have to back down a terrible situation. The trail to Williams lake is great and the round trip from the Hell Roaring Trailhead is 4.5 miles. When you reach the lake go left and you can get to a big rock and the deepest part of the lake. Lake is shallow and temperature is reasonable we will be back with swimsuit later.
