"Pearson's Canal Companions" have achieved cult status with canal users of all kinds. These lively, colorful and committed books are generally regarded as the most detailed, informative and down-right entertaining guides to the inland waterways. Each of the nine titles in the series covers a popular route or area with large scale and highly detailed maps accompanied by a wide ranging commentary, descriptions of waterside towns and villages, and itemized listings on eating and drinking, shopping, visitor centers, public transport and boating facilities. Of particular use to walkers and cyclists is the classification of towpath conditions into three grades. Considerable coverage is given to items of industrial archaeological interest. The Welsh Waters canal network includes the Shropshire Union; Llangollen; Monmouthshire and Brecon; Mongomery canals.
