At an elevation of 1,721 feet, the Lower Rock Castle Creek Trail forms a 4.5-mile leg of the 11-mile loop called Rock Castle Gorge Trail. This trail follows a gated fire road alongside Rock Castle Creek. Surrounding the creek bottom is mixed deciduous forest, which house many nesting neotropical migrant birds. Creek beds are good places to spy on native brook trout (the lure for local anglers), but also a good place to hunt for salamanders. Northern dusky salamander is abundant, but several other species are likely to be present as well. Camping is available at this site only with a backcountry permit. CONTACT the Rocky Knob Knob Campground or Visitor Center for a backcountry permit.
