Located in the rural, isolated hills of far northern Lancaster County, the Middle Creek Trail is also clearly the wildest and least-known of the region's numerous greenways. Although the trailhead off Mountain Spring Road includes a decent-sized, gravel parking lot, the terminus at Klinefeltersville Road (which is also where the Horseshoe Trail crosses) is little more than a pulloff along the shoulder. Also, neither end is well-signed, meaning you have to know the location of the trail ahead of time. Finally, the surface of the trail is either dirt or coarse stones that appear to be left over from the ballast of the defunct trolley line that it follows, making it more like the adjacent Horseshoe Trail or other primitive footpaths than the asphalt or crushed stone surfaces that most rail trails are noted for. Unless you have a mountain bike, this trail is not for cyclists; it is definitely a hiking trail. I would also advise using caution if the weather has recently been rainy; although there are boardwalks that allow users to cross some of the muddier sections, some fo these are in poor condition. On the plus side, this is an awesome trail for nature hikes and enjoying the pristine beauty of Lancaster County's Furnace Hills. Lush forests dominate the landscape on its entire length, and the waters of Middle Creek are never that far away. Finally, although the line, which once provided trolley service between Lebanon and Ephrata, was abandoned around the time of World War II, it is surprising how much of the old grade is still intact. In addition to the ballast that now serves as pavement for the southern half of the trail, the abutments to the old bridge across Elders' Run are still in place and now support a small, wooden footbridge constructed by the Pennsylvania Conservation Corps. As others have stated, the trail is best enjoyed on conjunction with the nearby Elders Run and Horseshoe trails, which form a loop through the lovely woodlands of the Middle Creek Wildlife Management Area and adjacent State Game Lands.
