When visiting the United Kingdom for an extended period, you must visit all four countries to get a complete picture of the places that make up the UK. In the west of the UK, Wales is an incredible country filled with breathtaking natural landscapes, world-famous beaches and vibrant cities.

The Welsh have their language, Cymraeg, which only a tiny percentage of the population is fluent. The longest place name in the world is in Wales and is written in Cymraeg. Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch translates to ‘St Mary’s Church in the Hollow of White Hazel near a Rapid Whirlpool and the Church of St Tysilio near the Red Cave’. Unsurprisingly, the town’s name has been significantly shortened by locals.

Wales might be a land filled with natural beauty, but its history equally alluring for visitors. For its size, Wales has more castles than any other country in Europe, including the second largest in the UK, Caerphilly Castle.

Wales has many famous links, including the birthplace of author Roald Dahl. Mount Everest was named after Welshman Sir George Everest, a surveyor who mapped the mountain. Here are 20 incredible natural and historical landmarks in Wales not to miss seeing in this proud and beautiful country.

The surrounding area makes for a pleasant hike through unusual rock formations and unique plant life.

Local legend tells of a 12th-century prince who entrusted his son, Idwal, to a friend.

In a rage, the son pushed Idwal into the lake, causing him to drown.

Banishing the friend and son, the prince named the lake after poor Idwal.

According to the tale, birds will not fly over the lake’s surface, and during storms, you can hear a wailing cry echoing around the Cwm.
