The Union Jack, the Queen and lively pubs are among some of the quintessential images that portray the UK. But beyond these clichés is a country with great history and some of the most wonderfully diverse landscapes on the planet. Made up of England, Scotland, Wales and Northern Ireland travellers thinking of a trip to the UK could find it hard to choose just one place to visit. The obvious choice might be England and its thriving capital London or the seaside town of Brighton and the picturesque villages of Cornwall. Those in search of a little more adventure or an active holiday should head to Wales where its mountainous terrain and hiking trails will keep even the most jaded adventurer agape.
The cities of Scotland, particularly Edinburgh and Glasgow, are always popular with travellers to the UK. But venture further north to Perthshire and the Grampian hills of Angus to get a taste of the rich Scottish countryside. The counties of Northern Ireland offer visitors travelling to the UK a range of activities including fishing, and rock climbing in County Down or strolling through acres of apple orchards in Armagh.
United Kingdom climate
The United Kingdom has a generally mild climate. Wales gets most of the rain and Scotland and northern England has the most snow in the winter. The south experiences most of the mild, dry weather and the vast majority of sunny days.
When is the best time to fly to United Kingdom?
Peak season:
The UK is a year-round destination and travellers are eager to explore the country’s main attractions. Peak summer months are busiest, especially in London, and the major tourist centres. Summer (June to August) temperatures range between 14 and 30 degrees Celsius and the rainfall varies dramatically every year.
Off season:
Winter months (December to early March) can be cold (average temperatures about one-two degrees Celsius), but in general, the further north you go, the colder the weather. This is the time to visit for winter sports. Scotland has five main areas for winter sports: Nevis Range, Glencoe, Glenshee, Cairngorm and the Lecht.
Shoulder season:
Spring (March to May) and autumn (September to November) can be great times to visit. The tourist season is just gearing up (or gearing down) and the weather can be sunny and warm. May and September, in particular, can enjoy very good weather.
Getting around United Kingdom
There are domestic flight options for connection between cities around the UK.
Train service network is very extensive, if expensive.
In London, the underground rail is very comprehensive and covers most of the city. Buy an Oyster card at any Tube station to get around more cheaply. Buying a ticket at the station is much more expensive than using the card. There are trams in several cities including Manchester and Sheffield. Croydon has a Tramlink and Blackpool, the resort town in Lancashire, has the UK’s only remaining “traditional” tramway.
There are several bus companies providing a more economical way to get around the UK and offer a very good service. London buses are fast and regular, linking up the capital day and night. There are good bus services in other cities around England, Scotland, Wales and Northern Ireland. The Postbus is a nationwide service of more than 200 routes, mostly in remote areas.
Car hire is easy. All the major companies are represented at airports and in cities around the UK.
