The Stone Fly Trail begins on the West Plateau Loop
about halfway between its intersections with the Alum Hollow Trail
(the main trail in Green Mountain Nature Preserve). As of November 2017, the intersection and trail were not marked by signage. Rather, it is marked with brightly colored ribbons tied around trees.
This trail stays above the bluff, so there are no sustained or steep climbs. However, there are several small creek crossings to slow things down. For the most part, the trail meanders through the woods along Alum Cave Creek (the creek that feeds Alum Cave Falls) opposite the West Plateau Loop
. After the second creek crossing, the trail begins to approach the bluff and intersects with the hiking-only connector to the waterfalls.
After the waterfall connector intersection, the trail continues along the edge of the bluff with views across Alum Cave Hollow as well as Wade Point until reaching the Land Trust Boundary. At the Land Trust Boundary, the trail intersects with the Oak Bluff Trail, which is on privately-owned land and is difficult to follow in autumn. There are a number of additional trails and fire roads on private property which branch off of the trail in this area, so it is easy to get lost on this side of the preserve.
