Britain has some of the most extensive canal networks on the face of the planet, and for good reason; we invented the things (except for irrigation canals, the Romans used those). This means that travelling through canals will give you the opportunity to visit most of England, from old market towns, to massive industrial cities. You can experience much of the history of England and its empire by travelling along its causeways.
If you’ve come to realise that this is the case, then you may be considering buying your own barge to travel the length of England. There are certainly some advantages to this option, but it does require a lot of work to get a great experience from it all. You may well decide that sticking to renting rooms in barge B&B’s, or renting an entire boat, are better options, as it will require less work and you’ll have everything sorted out and ready for you to enjoy yourself.
