From the wilds of Northumbria (Northumberland and Cumbria) to the north, to Kent in the southeast and Devon and Cornwall in the far southwest, England is the largest of the four countries of the United Kingdom. It is also home to the vast majority of the population with well over 51 million inhabitants, out of the 61 million grand total.
Northern Ireland occupies the north-eastern corner of the island of Ireland. It has a population of just over one and a half million people and this only makes up 2.5% of the UK total.
With a population of over 5 million people, Scotland is the second largest country of the United Kingdom. It is also the most rugged with vast areas of mountainous terrain covering great swathes of the country. Scotland is also made up of a myriad of islands: an archipelago of dozens of these can be found lying to the west and these include The Hebrides; to the north you will first reach the Orkney Islands and then if you continue in the same direction, you will reach the most northerly part of the UK, The Shetland Islands.
Wales occupies a large peninsula that juts out into the Irish Sea and the border with England is found to the east. As with much of the western side of Great Britain (the mainland island of the UK), Wales is predominately made up of very hilly landscapes. The Brecon Beacons in the south and east and Snowdonia National Park (in the northwest) are the most mountainous regions.
