The Oak Creek canyon road was closed. Even hiking wasn't allowed so we found a different way. Ken and Karen Jones were down from Washington state to do this one and this is what Ken came up with (on his trip report at peakbagger.com)
"The normal route to Fool Creek Peak was closed by a fire last year. According to signage at the gate at the forest boundary in Oak Creek Canyon, the length of this closure is indeterminate. Entering the area will subject you to fine and/or jail.
What to do? Well, the map accompanying the closure order showed that everything south of the summit trail was closed, but the trail itself was the boundary of the closure. So we went around the north side and climbed from there:
From the junction of Utah routes 125 and 132 go south on higway 125 to the hamlet of Fool Creek. This is about 4.4 miles south of the junction. Here you will find a national forest access sign to "Fool Cr Cyn" and a gravel road heading SSE.
Follow this road as far as your vehicle will allow. These waypoints may help:
0.0 Leave Hwy 125
2.0 Cattle guard, forest boundary
2.1 Keep left
2.8 Go straight, ignore road to left
5.7 Keep right
6.2 Park - this is near "Upper Narrows Spring" on your topo
The trail goes up the stream, and is easy to pick up after you get through the berms and washed out area just above the parking spot. When you top out on the ridge, go left and follow the trail to the summit."
While Ken and Karen went for Fool Creek Peak, I went over and did Buck peak.
