Narrow boat vacations -- cruising canals: one of the greenest holiday options you can take. In the UK you're never far from a canal. Karen and Richard Holt have run Leeds and Liverpool based hire company Canal Boat Escapes for the last six years. They have taken things one step further and actively encourage their customers to be as environmentally aware as possible. For the last two years they have gained silver in the Green Tourism Business Scheme and a number of other regional awards.
