We will be in the Smoky Mountains at the end of December and would like to do some short- moderate hikes to some recommended sites, possibly waterfalls. We really wanted to go to Cades Cove, but apparently the road is closed during this time. I read through a few other posts, but didnt really find answers to what we are wanting to do. We are staying in Gatlinburg and would like to do one or two hikes during the day. What will be open during that time? Thank you in advance.
