The biggest change for Americans in 2026 is at the UK border. Here is what to do before you fly, and how Ireland fits in.
Since February 25, 2026, US citizens must hold an approved Electronic Travel Authorisation before boarding any flight, ferry, or Eurostar train to the UK; the grace period is over. The fee rose to 20 British pounds per person on April 8, 2026. One ETA covers England, Scotland, Wales, and Northern Ireland, allows multiple visits of up to six months each, and lasts two years or until your passport expires, whichever comes first.
Copycat websites charge 40 to 60 pounds or more for the same authorization, with no faster decision. Apply through the official UK ETA app or GOV.UK. Most applicants hear back within minutes, but allow up to three working days. If you renew your passport, your ETA ends with the old one, so apply again with the new passport before your next trip.
The Republic of Ireland does not use the UK ETA, so a trip to Dublin, Galway, or Killarney needs only your passport. If you cross into Northern Ireland for Belfast and the Causeway Coast, you need a UK ETA, even though there are no checks at the land border.
The UK and Ireland are outside Europe's new biometric Entry/Exit System. If you add Paris, Amsterdam, or a river cruise to a British Isles trip, you will register your fingerprints and photo when you enter the Schengen area. Our Western and Central Europe guide explains what to expect.
Apply for your ETA only at the official GOV.UK ETA page or the UK ETA app.
Fast trains and excellent coach tours mean you can base yourself in one comfortable city and still see castles, cliffs and countryside. Every guide has a section of senior-friendly tours with live prices from Viator, and these compare the best day trips, with travel times and how much walking each involves:
Rail tip: if you are 60 or over, the Senior Railcard (35 pounds a year) takes a third off most train fares in England, Scotland and Wales, and visitors can buy it.
The UK and Ireland reward senior travelers with history, scenery, and a shared language, and three starting points stand out. Scotland pairs Edinburgh, one of Europe's most walkable capitals, with the wild Highlands and the Isle of Skye. England ranges from the museums and theatre of London to the honey-stone villages of the Cotswolds and the Georgian elegance of Bath. And Ireland offers Dublin's literary warmth, the Ring of Kerry, and the dramatic Cliffs of Moher on the Atlantic coast.
Most US travelers come for the classic Scotland-and-Ireland trip, and two weeks is the sweet spot: a few days in Edinburgh and the Highlands, a short hop to Belfast and the Causeway Coast, then Dublin and the west of Ireland. With ten days, focus on one country and a single scenic add-on. With a week, pick one capital and travel gently rather than rushing between regions.
Our guides cover Edinburgh, Dublin, London, the Isle of Skye, and the Scottish Highlands and Loch Ness, and the Cotswolds, Killarney & the Ring of Kerry, Bath, Galway & the Cliffs of Moher, and Belfast & the Causeway Coast, with the Isle of Skye, the Scottish Highlands and Loch Ness, the Cotswolds, Killarney and the Ring of Kerry, Bath, Galway and the Cliffs of Moher, and Belfast and the Causeway Coast to follow. Each is chosen for how well it suits travelers over 50: walkable centers, strong public transport or easy guided tours, and scenery that rewards an unhurried pace.
Late spring and early autumn give the best mix of mild weather, long daylight, and lighter crowds, while summer is warmest and busiest. You rarely need a car in the cities, which are best on foot and by train, but a guided day tour is the easiest way to enjoy rural routes like the Highlands or the Ring of Kerry without driving on the left. Each guide covers the best season, costs, and accessibility in detail.
