I am looking for direction as to best direction to go for a very small backpacking trip of 15-20 miles with my 11 and 13 year old. I want to start at Clingmans Dome and go about 7- 10 miles in either direction. The other option is go north and do same distance to the top of Mount Washington or maybe something in Vermont. Any advice would be great. I am a seasoned ultra runner, my kids not so much.
