i highly recommend going to Soddy Daisy, TN. drive up Hot Water Rd. all the way to the very top. you will see a small gravel pulloff on your left at the top, and you can hike down to the bottom of the area that eventuall leads to the bluff above Depot St and Soddy-Daisy way down below.. there is an old piece of "Ore car Rail" and some topographical features and signs of the old Daisy Coal Co, and Soddy Mining Co, as well as a beautiful hike all around, and has 2 different trails to hike. I wouldnt describe it as easy.. Also if you ever get the chance, check out everything Raccoon Mountain has to offer. You will not be disappointed. The history of Raccoon Mountain and everthing else aside from the tourist things that there is to do (The Information Center at the very top is free iirc, and outside of the visitors center there is breathtaking, as well as other points all along the Raccoon Mountain, including the other side where you can fish or get amazing pictures and videos of the The River Gorge(A.K.A."The Suck" , as before the water current interruptors installed for the elctric plant literally in the center of the mountain, which was a nautical nightmare prior to TVA, it was known as Suck Creek, and the currents would literally change direction so rapidly through the area it would sucks barges and watercraft under)..
I live in Chattanooga!! This was exciting to see. My husband and I have a youtube channel where we river treasure hunt. So we have been to most of these places!!
