There were many exciting moments at the start of this tour that made me think it would have been enough just to have done this and gone on to London, but we were, in fact, going north to see more wonders, such as Chatsworth House and Haddon Hall in Derbyshire, and then on to Yorkshire to visit Harlow Carr, the famous RHS garden, and then up to Alnwick Garden with its wonderful water cascade and poison garden in Northumberland.
