We live pretty close to the towpath and know the northern section well. My only caution would be crowds on nice weekends, or during special events. The CVNP is primarily near urban areas until south of Akron, and can resemble a bike, walk, run, wander wobble freeway at times. I've seen my share of bikers ride right into the canal
That said, it's a really nice and easy ride with enjoyable relax stops along the way. PM me for more specifics, or if you need any kind of logistics help.
