Not sure what the "backside" is, but you can still catch the canyon at what they call the mouth of the park. This is the lower section of the canyon....the portion with rough roads. It runs along the lower half of the canyon and connects at the split, at which point you can branch off and start heading towards Desoto. From this point, you can only ride 176 about half of the distance to the falls before the road detours onto Co Rd. 255, which then connects to 78 and spits you out onto 35 (Ft. Payne side of the falls). I was there on Sunday and talked to a couple of park rangers. They informed me that a section of the road had washed out. If you ride the road often, it's where the "DIP" sign is. They really didn't give me a estimate on downtime, but then again....I'm sure I forgot to ask. I ride the road pretty frequently, so I'll try to update unless someone beats me to it.
