“The South Run Stream Valley Trail runs from Burke Lake past Lake Mercer and another 2 miles beyond.”— Victor Stephenson
Near the South Run Recreation Center the Lake Mercer South Loop Trail branches off to the south side of Lake Mercer and then rejoins the South Run Stream Valley Trail at the Lake Mercer Dam allowing for a loop around Lake Mercer. The South Run Stream Valley Trail continues around the north side of Lake Mercer and continues eastward for another 2 miles beyond ending at Rushing Creek Road.
The first 1.5 miles are paved and more than doubletrack wide. Then there is a short .15 mile section of gravel service road. The trail then returns to paved, doubletrack+ width for the next 2.85 miles. At that point, it crosses South Run stream and becomes paved singletrack for its remainder.
