Caen Hill Lock Flight

Today I met my friend J from Cornwall. We both drove to the Caen Hill Lock Flight on the Kennett and Avon canal near Devizes.
There are 29 Locks in total in the Flight, with 16 of them in the steepest section. From speaking to the boaters today, it can take up to five hours to complete the Flight.
I think it depends on how long you have to wait if there are boats coming the other way!
I have included a few extras.
