Falling water, that would be an interesting side trip. I'm going to give a half-thumb up to the New River Trail down nearish to Virginia Tech. Half-thumb because: never gone the entire length & last ride was years ago on it so perhaps it has changed. But when I did it, it's nice -- a little overgrown in places. I did it then on a road bike with some cyclo-cross tires I stuck on it. I'd probably not do that again though.

Not sure what the rail line is or was....
