United Kingdom travel guide

The United Kingdom brings together England, Scotland, Wales and Northern Ireland, from London's museums and theatres to Highland glens, prehistoric stone circles, castle-topped towns and coastal paths. Distances are short but variety is huge, so it suits city-breakers, walkers and history lovers, especially those willing to venture beyond London.

Highlights

London

Many of the major museums, including the British Museum, the Natural History Museum and Tate Modern, are free to enter. Add the Tower of London, Westminster Abbey, a West End show, Borough Market and walks along the South Bank of the Thames.

Edinburgh

Scotland's capital is built around a castle on a volcanic rock, with the Royal Mile running down to Holyrood Palace and Arthur's Seat rising behind. In August, the Edinburgh festivals take over the city.

Scottish Highlands and Skye

Lochs, mountains and single-track roads. Drive through Glencoe, search for the Loch Ness monster, and on the Isle of Skye see the Old Man of Storr and the Quiraing. The North Coast 500 route loops around the far north.

The Lake District

England's largest national park, with fells to climb, lakes such as Windermere and Ullswater, and the homes of William Wordsworth and Beatrix Potter. It is a UNESCO World Heritage site.

Bath and the Cotswolds

Bath has Roman baths and Georgian crescents in honey-coloured stone. The nearby Cotswolds are rolling hills dotted with villages of the same stone, such as Bibury and Chipping Campden.

Stonehenge and Avebury

Prehistoric stone circles on Salisbury Plain and in Wiltshire, built over many centuries from around 5,000 years ago. At Avebury, the circle is so large that a village stands partly inside it.

York

A walled medieval city with York Minster, one of the largest Gothic cathedrals in northern Europe, the Shambles' overhanging timber houses and a Viking heritage centre.

Eryri (Snowdonia) and the Giant's Causeway

In north Wales, Yr Wyddfa (Snowdon) can be climbed on foot or by mountain railway, with castles at Conwy and Caernarfon. On the north coast of Northern Ireland, the Giant's Causeway is a headland of tens of thousands of interlocking basalt columns.

Interesting facts about United Kingdom

  • The London Underground, which opened in 1863, was the world's first underground railway.
  • The UK has no single written constitution; its constitution is made up of laws, court rulings and conventions.
  • A village in Anglesey, Wales, has one of the longest place names in Europe: Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch.
  • Welsh is an official language in Wales, and road signs there are bilingual.
  • Scotland has around 280 mountains over 3,000 feet, known as Munros, and climbing them all is a popular challenge.

Best time to visit

Late spring (May to June) and early autumn (September) often bring the best balance of mild weather, long days and fewer crowds. July and August are the warmest and busiest months, with school holidays and festivals. In the Scottish Highlands, midges can be a nuisance in summer, especially at dusk. Winter is cool and damp with short days, particularly in Scotland, but cities are lively with Christmas markets, theatre and museums. The weather can change quickly at any time of year, so pack layers and a waterproof.

Getting around

Trains link most cities, and booking advance tickets online can make a large difference to fares. In London, contactless bank cards and phones work on the Tube, buses and trains, with daily caps. Long-distance coaches are cheaper but slower. Domestic flights and ferries reach the Scottish islands and Northern Ireland. For rural areas, national parks and the Highlands, hiring a car is often the most practical option; many rural roads are narrow, and some in Scotland are single-track with passing places.

Staying connected in United Kingdom

Mobile coverage is good in cities, towns and along main roads and railways, with 4G across most populated areas and 5G in many cities. Coverage is patchier in the Scottish Highlands and islands, in parts of Wales and in some national parks and rural valleys, where you may have no signal for stretches. Free Wi-Fi is common in cafés, pubs, hotels, museums and on many trains. Download offline maps before visiting remote areas. Install an eSIM before you fly and switch it on when you land.

Common questions

Can I use contactless payments in the UK?

Yes, almost everywhere, including London transport, pubs and market stalls. Some places no longer accept cash, but it is still useful to carry a little in rural areas.

Can I use my phone in the UK?

Yes. Coverage is good in most populated areas, with gaps in the Highlands and rural regions. If your home plan's roaming is expensive, a travel eSIM gives you local data for maps, transport apps and contactless payments.

Do I need a car to travel around the UK?

Not for cities, which are well connected by train. A car helps in the Highlands, the Lake District, the Cotswolds and Wales, where public transport can be infrequent.

What plug adapter do I need for the UK?

The UK uses Type G plugs with three rectangular pins, at 230 volts. Most visitors from outside the UK and Ireland need an adapter.
