I followed part of the Old Johnsonville Trail and the Civi War Trail. A 0.6 mile section is closed down for an undetermined time due to rerouting the trails. Be sure to stop in the welcome center to get the map and they can mark off the section that is closed. The trails are marked well with blazes on the trees and anytime another trail intersects or a short cut is offered, there is a marking post that coincides perfectly with the map. One of the more accurate maps I’ve seen in awhile. Different civil war artifacts throughout the park and trails. Biggest bonus of this trail system is that nearly all of it is under the tree canopy but they also means you need bug spray. The map says the blue and red trails are difficult and they are not. The blue Trail is easy with moderate sections. The red trail is moderate with one short difficult section.
