Wales is a country that has everything to offer you: from its towns' and cities' beauty to its landscapes' beauty and wealth. If you are a nature lover, then Wales is exactly what you need: you can enjoy the country's beautiful beaches - even though it might be a little too cold to have a swim; or you can climb the Snowdon. Wales is also home to gorgeous monuments, especially castles, such as the Cyfarthfa castle. If you are a sport lover, then Wales also has something to offer you: you can do some coasteering - which is a "unique adventure sport where you experience the exhilaration of sea level traversing, rock climbing, cliff jumping and swimming into sea caves"; or you can do some Bog Snorkelling, "a sporting event that consists of competitors completing two consecutive lengths of a water filled trench cut through a peat bog, in the shortest time possible". But of course if you prefer simple sports such as cycling or horse riding, the beauty of Wales' nature will allow you to enjoy these activities in an exceptional setting.
Finally, we can't talk about Wales without talking about Cardiff, its beautiful and dynamic capital. Whereas you can walk during several kilometers in Wales without seeing anyone, this won't be possible in Cardiff, because there are 319 700 people living there. The size of the city will allow you to do everything on foot. There are a lot of things to visit there, but while you are there, make sure not to miss the three most important attractions of the city: the Millennium Stadium, the National Museum and the Cardiff Castle!
