Wales’ capital is a city that can be enjoyed by any traveller, no matter what their interest. Effortlessly balancing history and modernity, it provides entertainment in all forms, including theatres, museums, excellent restaurants, and monuments. Cardiff is a master at exceeding expectations, and won’t fail to impress you with its various attractions. 

Aside from the city itself, it’s hard to not be impressed by the famous Welsh hospitality, which sees visitors treated like close friends. As soon as you leave, you’ll be counting down the days until you can return, so make sure you make the most of it while you’re there.

Top 5 things to do in Cardiff:

Wales Millennium Centre. This arts centre and venue embodies Wales down to its foundations, as it’s made exclusively out of local materials including slate and wood.

Spillers Records. First opened in 1894, Spillers is officially the oldest record store in the world, and still stocks a huge range of vinyl.

Cardiff Central Market. A truly traditional experience, Cardiff’s Central Market has played host to a variety of stalls since the 18th century.

Cardiff Castle. Dating back to 50AD, Cardiff castle was remodeled in the 19th century by the hugely wealthy 3rd Marquess of Bute. The extravagant interior reflects this, and needs to be seen to be believed.

The National Museum. Houses a huge collection of art, local history, and even archaeological finds including the skeletons of woolly mammoths and dinosaurs.
