It's a popular misconception that the Canal Companions are 'ring' orientated when half of them don't feature circular routes at all. This one's a case in point. Moreover, however hard we try, and whatever effort we put into the other Companions, this is perennially the most popular, out-selling some of the more arcane Companions by 5 to 1.
Mystifying? Well, not really, the Llangollen Canal has always been the honeypot of the canal network in the leisure era, and the Shropshire Union, also fully covered in this guide, doesn't lag far behind.
Throw in the beautiful (but isolated) Monmouthshire & Brecon Canal, and the slowly emerging Montgomery Canal (a real treat for walkers and cyclists) and it isn't difficult to explain this guide's popularity.
