United Kingdom travel guide

Getting there

London Heathrow and Gatwick are the main international gateways, with major airports also in Manchester, Edinburgh and Birmingham; Eurostar trains run through the Channel Tunnel and ferries link to France, Ireland and beyond.

Best time to visit: May–Sep – long days and the best chance of mild, dry weather.

Tougher months: No bad time – November-February is cold, grey and dark early, but cities, museums and festive markets make winter enjoyable.
