You can drive to plenty of mountain overlooks and waterfalls in the area including in the park. Try Helton creek falls within 2 miles of the park Ask what is in the area. We were there 4 days and didn't see it all but kept busy

Also turn left out of the park and visit (free) the first place on the left called Byron Reese Farm and Heritage Center for a great free map of area attractions(Reese was a famous poet and author and this was his home and farm with live animals). There is plenty to do in the park but you are within driving distance of :Helton Creek Falls..Desoto Falls..Brasstown Bald..UnicoiState Park(which contains. Anna Ruby Falls &Barvarian Village of Helen)and 12 other great places.
