Just south of Smith Hill is Tyndale Hill. This is another area that when I visited it in the fall of 2006 was park property but was closed to visitors. Luckily I happened onto that ranger led tour. Access to Tyndale Hill is from behind the McDonald's at the Brown's Ferry exit off the interstate. You have to park at the bottom of the hill, just about in the McDonald's parking lot, and walk to the top. At the time the park service had yet to cut any trails into the area, I'm not sure if they have done so yet. So with the ranger in the lead we did a bit of bushwhacking. If you're going there you should probably check at a visitor's center before you go wandering around this area.
From the top you have a nice view of Lookout Mountain.
There are also some entrenchments still visible. Even though Tyndale's Hill achieved its name for the October fighting, these entrenchments are most likely for the November fighting as they face Lookout Mountain
