I spent a week in France doing the Brest/Nantes canal in Brittany.
Now when I say “doing” I use that word in the same context as our overseas visitors “Do” London or even “Do” Europe. We had a short but pleasant walk in the autumn afternoon sun along the path. The canal was built to maintain a connection between the military ports of Nantes and Brest when the pesky Brits blockaded Napolean I’s port of Brest.
I would have cruised the whole canal in the week apart from 4 small reasons. First it would be well over 200 miles long, secondly there are un-navigable parts en route, thirdly French locks are closed for the winter now, and finally we didn’t have a boat. So a short walk sufficed to “Do” the Brest / Nantes canal this time. Maybe another year.
