Falls Creek Falls Trail is wonderful hike which if you like running, has a great running surface and less steep elevation profile than many hikes in this area.
Located 12 miles North of Carson, on Wind River Road. The hike can be done as an out-and-back (3.5 miles) or by a choice of two loops, 4.5 or 6.5 miles. It's all beautiful. The falls are breathtaking.
