Local Area
There is plenty to do in Cardiff city centre, as well as a little further afield.
You can find a great compilation of things to see & do in and around Cardiff, as well as places to eat & drink, places to stay, and other information, in the Visit Cardiff website.
Amongst the unmissable things of Cardiff, is the Cardiff Castle and its grounds, enclosed by walls that were used as air raid shelters during WWII. The Castle is surrounded by the large and very well maintained Bute Park to the north, and provides a beatiful view of the city centre to the south, all the way to Cardiff Bay. Entry to the castle grounds is typically free (unless there is an event taking place), but you will need a ticket to visit the walls, the fort, and the gothic palace.
The pedestrianised city centre of Cardiff is very lively, bursting with restaurants, bars, and shops, and a couple of museums (including the National Museum of Cardiff). Cardiff is also known as the City of Arcades due to the seven Victorian and Edwardian arcades that nestle amongst the city centre streets. The Cardiff Principality stadium (once the Millenium Stadium), home to the Welsh rubgy team, is also impressively set right in the city centre.
With a short bus or train trip from the city centre, you can also reach Cardiff Bay, home of the Welsh parlament, the Millenium centre, the Pierhead (a historic grade one listed building, now a museum), and the Cardiff Bay barrage (that copes with impressive ~10m tides and keeps Cardiff dry - well.. let's say not flooded!).

The LOC have put together a (naturally incomplete) list of recommended places to eat and drink in Cardiff, that attendees who don’t know Cardiff well may find useful.
