Start your journey in London. Noisy, vibrant and truly multicultural, London is a megalopolis of people, ideas and frenetic energy. The capital and largest city of England, and of the wider United Kingdom, it is also the largest city in Western Europe and the European Union. Situated on the River Thames in South-East England, Greater London has an official population of a little over 8 million, but the estimate of between 12 and 14 million people in the greater metropolitan area better reflects its size and importance. Considered one of the world's leading "global cities", London remains an international capital of culture, music, education, fashion, politics, finance and trade.

Glasgow (Gaelic: Glaschu, Scots: Glesga) is the largest city in Scotland and the fourth-largest in the UK; with a population of about 600,000 in the city itself and over 2,000,000 if the surrounding towns of the Clydeside conurbation are taken into account. Located at the west end of Scotland's Central Belt on the banks of the River Clyde, Glasgow's historical importance as Scotland's main industrial centre has been challenged by decades of socio-economic and political change alongside various regeneration efforts. Despite this, Glasgow remains one of the nation's key economic centres outside of London. Glasgow was awarded the European titles of City of Culture (1990), City of Architecture and Design (1999) and Capital of Sport (2003). In 2008, Glasgow became the second Scottish city to join the UNESCO Creative Cities initiative when it was named as a UNESCO City of Music. In preparing its bid, Glasgow counted an average of 130 music events a week; ranging from pop and rock to Celtic music and opera. The city has transformed itself from being the once mighty industrial powerhouse of Britain to a centre for commerce, tourism, and culture. It was the host city for the successful Commonwealth Games in 2014. Glasgow has become one of the most visited cities in the British Isles, and visitors will find a revitalised city centre, the best shopping outside London without a doubt, excellent parks and museums (the majority of which are free), and easy access to the Scottish Highlands and Islands.
