We are planning a trip to the UK in early June 2019. We are interested in hiring a narrow boat for the four of us and I would like advice about which canals to explore. Our time will be one week, and we would like to be more in the countryside than the industrial cities. Quaint villages and hopefully an aqueduct or two would be fun. We don't mind locks and we will probably want to have bicycles on board. Any ideas? Also, which companies would you recommend?
