The park is a gem and the Natural Bridge is something you need to experience. I go every year but I won't take the little ones onto the bridge.  It is easy to fall if you are not paying attention. For my friends that can hike a short distance we will also take the chair lift up or down. You can do both.  It really depends on the weather and the trail as to how we tackle the trail. The chair lift is a small fee and well worth the view. 

Cell phone signals are hit and miss down here so make sure you have a clean plan for connecting with folks prior to parting ways.
