Enter the trail off Brown road or from the Golf Course Trail (Orange Blaze). From the Orange Loop stay right and the singletrack trail will lead you around the edge of the grass field before entering the woods again.
Follow the trail (there are several un-blazed trails available to runners and mountain bikers) along the hillside and around the gully. The final stretch before jumping on to Brown road crosses over a small creek/marshy area. Once on Brown road, go right to head to North Park area.
