Always leave something for the next visit... These are the things I didn't to in Cardiff so far and that I want to do when going back!
Pay another visit to Alexandra Gardens - to spend more time there and take some pictures
Turner House Galley - permanent collections and changing exhibitions of fine art and photography
Boat trip to Flat Holm Island - a nature reserve island where you can go on a sailing day trip
Cosmeston Medieval Village - a reconstructed village from the 14th century
I was really taken by the elegant wrought iron lamposts along the Esplanade. Those further up the hill were more modern and less attractive. My daughter commented on them later too.
Fondest memory: The elegance of the town. The grey limestone buildings are striking, and particularly I admired the Carnegie Library, though was unable to take a picture- next time.
