Permits are required and can be obtained at the main parking lot.
Start off on the Firebreak trail and cross Lost Creek Drive to the Lost Creek loop.
As with most of the Harbison trails, Lost Creek Trail takes you through a mix of pine and hardwood forest.
While there are a few straight sections, this is mostly a winding trail. There are also quite a few short and steep dips through creek beds, although they're normally dry.
The trail is mostly hardpack with a lot of roots and embedded rocks. There are also many areas that are typically covered with pine straw, so watch your footing as it can cover the roots and rocks.
Lost Creek is an excellent choice to add mileage to the more popular Harbison trails and is typically less busy.
