Sandwiched between Fox Mill Road and West Ox Road and bordered by Folkstone Drive to the north, this fun little loop of singletrack in Oak Hill, VA (Herndon) is hardly known. This is not an overly challenging trail, but it does have a few technical spots. In a few cases the trail comes right to the edge of a six-foot drop-off into the stream. Also, there are a few marshy places with thin wooden bridges that make for an interesting challenge.
From West Ox Road travel east on Folkstone Drive. In about two tenths of a mile you will see a guard rail in front of the woods on the right hand side. Just at the end of the guard rail is the beginning of a trail. There is no sign for the park; just a small post with a FCPA sticker and a blue dot. From the Fox Mill Road side; go south on Fox Mill Road and turn right onto Westwood Hills Drive. On the right, there will be a small field with a sign that says Folkstone Park - Little Difficult Run Stream Valley Park. In the back left of this field the trail begins.
