We rode Cumberland Ridge trail and Jacks Ridge loop back in June.
I rode with front boots only and really didn't find BSF to be a difficult ride when compared to the trails in the Cohutta's of N. Georgia or the Great Smokey Mountains.
The park service takes pretty good care of the trails and I don't think my horse stepped over a log the whole weekend. There are a few rocky spots but during June the trails had a lot of mud bogs.....
It's a pretty place to ride and geared for the equine community.
For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
