Come over the Rochdale, its grand! The only places not to stop are Newton Heath and Rochdale itself, as others have said. There are similar badlands on the L&L too, Armley Leeds,bits of Burnley and Blackburn.
What's a few locks, it's a Canal! Plenty of places to stop, Hebden Bridge, Todmorden, Littleborough, have great shops for provisions. The scenery around the summit is amazing, more stunning than anything on the L&L. Go to the Hepworth gallery in Wakefield.
What? ME? Biased? Nah, I just live and moor near the top of the hill, Littleborough Summit.
Ps, you can ask for the help of a volocky going down into Manchester, just ask CART. We got one last time we went through he was great, a good help.
