When i went to Leamington Spa on the train earlier in the month i noticed how close the canal is to Hatton station on the same line. In fact most stations along the Chiltern Line seem to track the Grand Union Canal (at least as far as Leamington anyway). Today i visited Hatton and had a nice canal walk up to Hatton Locks which is quite an attraction. The locks are very interesting with double boat locks, waterfalls, service bridges the works!
I shall be visiting here again soon i suspect, i had to make my visit fairly brief as i had a train to catch (though it was late anyway). I took a lot of photos today, along the canal and of the Warwickshire countryside, you can see the set here.
