Communication of information between neurons is accomplished by movement of chemicals across a small gap called the synapse. Chemicals, called neurotransmitters, are released from one neuron at the presynaptic nerve terminal.
Follow Trail 12 until it runs back into trail 1 and familiar sights and then you are only about 200 yards from the great Cumberland Falls. To the best of my guessing ability I would say this loop was about 8.5 miles long which took us about 3 hours and 45 minutes.
Personal horses are not permitted on the trails at Cumberland Falls State Resort Park, but there are several opportunities to do so in the surrounding area. There are many miles of trails and several horse camps in the nearby Daniel Boone National Forest and The Big South Fork National River and Recreation area.
