The directions on the app lead you to what I can only assume is some kind of service road. The actual trailhead is off of Hwy 125. Even once you get there, however, the trail markings are basically non-existent. There was one sign at the trailhead, I followed the trail in about a hundred feet to the creek & that was it. I will say the 2 hours driving I wasted were very scenic & this looks like a really pretty area if you want to bushwhack it.
I float swan creek after locally heavy rains from Garson to shadow rock park. This creek produces large standing waves that keep getting bigger as the creek rises instead of washing out. Bring your life jacket ! It's a great ride.
