Longest UK Rivers

25 Longest UK Rivers

There’s also no denying even the longest UK rivers don’t exactly cut the mustard when compared to the truly great rivers in the world. But what they lack in length they make up for in fame – the Thames and the Mersey, for example, punch well above their weight although none of the longest UK rivers make it into the list of the top 20 longest rivers in Europe.
