I am visiting Gatlinburg for a weekend getaway late January. I was considering family-friendly hiking at either Porters Creek trail or Kephart Prong Trail or go to the FoxFire Mountain instead. Would you advise which of the three do you recommend? I am traveling with 3 adults and 2 kids (2 and 5). I am not expecting to be hiking for too long in the cold, but at least get some time outdoors. Please advise.
