The complete guide

United Kingdom

From London's icons to Scotland's lochs and England's honey-stone villages — everything you need to plan a great trip, minus the guesswork.

Flight time 1–3h from Europe, 6–11h from North America, 20+h from Australia/NZ (with a layover)From $120–300 round-trip from Europe; $400–750 from North America; more from Australia/NZVisa No visa needed for tourist stays up to 6 months for most nationalities — but a paid ETA is required in advance*Time zone GMT/UTC+0 (BST, UTC+1, late March–late October)

The UK rewards 7–14 days: 4–5 in London, 2–3 in Edinburgh, and the rest split between countryside day trips (Bath, Oxford, the Cotswolds) or a proper Highlands/Lake District loop. Best months are May–September for weather and daylight, though April and October are the cheaper, calmer shoulder season. Most visa-exempt nationalities now need a paid ETA (£20) before arrival, not a visa. Budget from $70/day backpacking, $150–300/day mid-range.

The UK is a strange, wonderful mix of a country that somehow feels both smaller and bigger than it looks on a map — London alone could absorb your entire trip if you let it, while the countryside just an hour or two outside it feels like a completely different century. It's castles, yes, and rain, also yes, but it's also one of the world's genuine food capitals, some of the best museums on Earth (many of them free), and a night out at a proper pub that hasn't changed its personality in a hundred years.

This guide covers everything: where to go, how many days, when to fly, what it actually costs in USD and GBP, and the ETA rule for your specific passport — since 'do I need a visa' is no longer the whole story here. Written to be genuinely useful, and updated through the season.

Questions people actually ask

How many days do I need in the UK?
7 days covers London plus a day trip or two. 10–14 days lets you add Edinburgh and a proper regional loop — the Cotswolds, or the Scottish Highlands. Anything beyond 14 days and you can genuinely slow down rather than rush between cities.
When is the best time to visit the UK?
May through September brings the most reliable weather and the longest daylight (June evenings stay light past 9:30pm in London, past 10pm in Scotland). April and October are the value sweet spot — cheaper, calmer, and decent weather odds. There's no true dry season here in any month, so pack a rain layer regardless.
How much does a trip to the UK cost?
Backpacker budget: from $70/day (hostels, supermarket meals, free museums). Mid-range comfort: $150–300/day (a 3–4-star hotel, restaurant meals, paid attractions). A two-week trip for two people, flights included, typically runs $4,500–$7,500 mid-range, or well over $10,000 at the luxury end. London drives most of the cost; Edinburgh and the regions are noticeably cheaper.
Do I need a visa for the UK?
Most visa-exempt nationalities (US, Canada, Australia, EU, and roughly 80 others) don't need a visa for a tourist stay of up to 6 months — but as of 2025-2026 do need a paid Electronic Travel Authorisation (ETA), currently £20, applied for in advance. See our full ETA guide for the rules by passport.
Is the UK safe to visit?
Yes, very much so — violent crime against tourists is rare, and the country is considered one of the safer major destinations globally. The bigger practical risk is the weather (pack a rain layer) rather than crime; pickpocketing in crowded tourist areas is the main thing to stay alert for.
London first, or Edinburgh first?
Most itineraries do London first, since it's the main international gateway for long-haul flights, then take the direct train (about 4.5 hours) or a short flight up to Edinburgh. Either order works fine if you're flying directly into Scotland.
Which UK region should I add to a city-based trip?
Bath, Oxford, and the Cotswolds if you want an easy 1-2 hour add-on from London. The Scottish Highlands, the Lake District, or Wales if you have 3+ extra days and want the UK's wilder, more dramatic scenery — see our full London vs. Edinburgh comparison and regions guide for a direct breakdown.
Does eSIM work well in the UK?
Very well — Airalo and Holafly offer UK data plans from about $5-20 for 7-15 days with strong coverage nationwide. Local providers (EE, Vodafone, Three, O2, giffgaff) sell physical SIMs and eSIMs directly, often better value for longer stays.
