Any recommended spots near the triad area to backpack with my dog?

I recently lost one of my 2 dogs to cancer. She had health complications for years that prevented us from taking her on trips. I would really love to train my other dog to go camping with me. He is on leash 100% of the time because he is pretty reactive to animals and other dogs. I already know some spots I like in the Uwharries. Any other recommendations?
