Hazel Creek/Forney Creek Loop,North Carolina – 57 miles (5-6 days)
This park is America’s most-visited one but only a fraction venture to the section in North Carolina. Start at high Clingmans Dome and follow the Appalachian Trail before descending to Fontana Lake. Hikers will be able to take a dip at swimming holes, munch on wild berries, catch fresh trout and stretch out on giant rocks. The colors in fall are absolutely astounding.
