From the confluence with South Fork Creek down to Bull Hollow.
Look for the Greys River Road on the south side of the Greys River near where it joins the Snake River in Afton. Head up into the mountains along the main Greys River. In about 8 miles the road splits, with the main road bending sharply south, while the road up the Little Greys (Forest Service Road 10124) forks hard left. Follow the Little Greys road another 6.5 miles to where Bull Hollow Creek joins the stream on the north side. The instream flow segment extends another 4.5 miles on upstream to the confluence with South Fork Creek.
