Excellent canal guide. Uses Ordanance Survey maps and very clear symbols to show important information like water points, winding holes and pubs. Has excellent descriptions of the towns and villages you pass through saying what amenities there are and a little history of the places, also full of helpful tips and navigational notes. Covers a large area of waterways all in the one book which saves you money in having to buy several guides which cover just one canal. This is a must have for every canal boater.
