Beautiful walk, nice flat path.
This ever growing canal side trail is great for both hiking and biking, although given its largely nicely laid out and flat paths, it is a great opportunity for biking. I've always done random sections, usually the ones near Rochester, but for someone looking for a multi-day bike or hike, I imagine it would be fun to go for a full round trip of the trail, staying in a few of the small canal side towns as you go. The canal trail does a good job combining the nature of the area with the history of the canal. I also have also really enjoyed the few times I was able to see the canal locks in use.
Wonderful place to bike! You get a nice breeze from the canal even on a hot day. Be careful on the gravel portions of the path if you're biking--one of my friends had an accident with a stone that ended up giving her a concussion, so just use caution with how fast you're going in rockier areas.
