Jennifer and I met at the trailhead on Hall Road. The parking lot is good but the dirt road getting to it, not so good. There is no sign anywhere on the main road or this dirt road about the CT. We took our time, me nursing a sore back. But that helped us enjoy all the blooms and fungi. Flame azalea, Mountain laurel, and Rhododendren were all blooming along with Magnolias. There was a magnolia that had fallen in the forest and we got a close up look at the blooms. These trees grow so tall that you usually don't see the blooms unless you are looking up.
This is from the North Chickamauga Creek Conservancy: In the upper watershed, the hike from the Hall Road access point to Barker Camp Road consists of 10 miles of trail that runs along North Chickamauga Creek above the Cain Creek Confluence. This section passes the legendary Helican Blue Hole.
