UK ETA for Northern Ireland: What Walkers Need to Know
UK ETA for Northern Ireland: What Walkers Need to Know
Three of our routes cross into Northern Ireland — the Causeway Coast, the Cooley & Mournes, and Saint Patrick's Way. Northern Ireland is part of the United Kingdom, and since the UK introduced its Electronic Travel Authorisation (ETA), most of our guests now need one before they set foot on those trails.
It's a small thing — twenty pounds, ten minutes on your phone, usually approved the same day. But it's the kind of small thing that can turn into a very bad morning if it's missed. So here's the plain version, checked line by line against gov.uk/eta.
The one thing people get wrong
There's a widespread belief — and we're sorry to say an earlier version of this very page repeated it — that if you're arriving from the Republic of Ireland, you don't need an ETA.
That is not right, and it's the mistake most likely to catch our guests out.
The exemption is based on where you live, not on where you're travelling from. GOV.UK grants it only to people who are lawfully resident in Ireland. If you're a German, Dutch, French or American visitor who flies into Dublin and travels north to walk with us, you are not resident in Ireland — and you need a UK ETA. The Dublin flight changes nothing.
Do you need one?
Yes, almost certainly, if you are
A citizen of an EU or EEA country — Germany, the Netherlands, France, Belgium, Spain, Italy, Austria, Switzerland and the rest. This is where most of our walkers come from, and it is the group most often left off other people's lists.
A citizen of the United States, Canada, Australia, New Zealand or Japan, among other visa-exempt countries.
GOV.UK puts it simply: you usually need an ETA rather than a visa if you're from Europe, the USA, Australia, Canada or certain other countries. Everyone travelling needs their own — including babies and children.
No, you don't, if you are
A British or Irish citizen. (If you hold dual British or Irish citizenship, you cannot get an ETA — you travel on your British or Irish passport.)
Someone who already has a UK visa, or permission to live, work or study in the UK.
Lawfully resident in Ireland and travelling to the UK from Ireland — see below.
If you're not sure which box you fall into, GOV.UK has a checker: check if you need a UK visa or ETA.
If you live in Ireland
If you're a non-visa national who lives in Ireland lawfully, and you're travelling to the UK from Ireland, you don't need an ETA. But you must be able to prove you live here, and GOV.UK publishes a closed list of nine acceptable documents:
Irish driving licence
Irish learner permit
Medical card
GP visit card
European Health Insurance Card
Irish Residence Permit
Permanent Residence Certificate
National Age Card
Diplomatic identity card
The document must be an original, issued by the Irish government, and valid on the day you travel. Nothing else counts — there is no "or similar" category. Children under 16 don't need to bring proof at all.
Cost, validity and how to apply
It costs £20. Non-refundable. (You may still see £16 quoted on travel forums and third-party sites — that's the old fee.)
It lasts two years, or until your passport expires, whichever comes first.
Multiple entries, up to six months per visit.
It's linked electronically to the passport you applied with. No sticker, no stamp — and you must travel on that same passport.
What you need to hand
Less than people expect. GOV.UK asks for four things:
The passport you'll be travelling with
An email address
A credit card, debit card, Apple Pay or Google Pay
A photo of the face of the person applying
There's also a short set of suitability and criminality questions. That's the lot — no travel history, no employer details, no itinerary.
Where to apply
Through the official UK ETA app (App Store or Google Play), or online at gov.uk/eta/apply. The app is the easier of the two — it scans your passport and takes your photo with your phone camera.
You can apply for someone else, which is handy if you're organising a group.
How long it takes
GOV.UK says you'll get a decision by email usually within a day, and to allow up to three working days. Most people applying through the app get an answer in minutes.
Apply when you book, not the night before you fly. And wait for the confirmation email before you travel — you're meant to have the ETA in hand, not in progress.
⚠️ Apply through GOV.UK or the official app — nowhere else. GOV.UK warns that other websites may charge more and to avoid sites that imitate government services. You also cannot get a faster decision by applying through another website or app, whatever they promise. If you're being asked for more than £20, you're on the wrong site.
The bit we want to be very clear about
There is no border post between the Republic and Northern Ireland. GOV.UK says so itself: you will never go through immigration control at the land border. On our Cooley & Mournes route you'll cross it on foot and the only thing that changes is the colour of the road signs.
Nobody stopping you is not the same as nobody needing to. The Home Office is explicit that everyone arriving in the UK, including those entering Northern Ireland, still has to enter in line with the UK's Immigration Rules — and that includes holding an ETA if you need one. The requirement is real whether or not anyone checks it on the day.
An ETA is permission to travel. It doesn't guarantee entry, and it's not a formality you can sort out at the border — there's no counter to sort it out at. Do it at home, on the sofa, before you come.
Our Northern Ireland routes
Three of our walks take you across:
The Causeway Coast — the north Antrim coastline, past the Carrick-a-Rede rope bridge, the Giant's Causeway and the ruin of Dunluce Castle. Entirely within Northern Ireland.
Cooley & Mournes — begins on the Cooley Peninsula in County Louth, in the Republic, and crosses into the granite Mournes of County Down. This is the one where you'll walk over the border yourself.
Saint Patrick's Way — Armagh to Downpatrick, through County Armagh and County Down, following the trail of the man himself.
If you're booked on any of these, or thinking about them, sort the ETA early and forget about it.
Common questions
I'm German and I'm flying into Dublin. Do I really need one?
Yes. You're not resident in Ireland, so the exemption doesn't apply to you, and Northern Ireland is the UK. This catches a lot of people — it's the reason we rewrote this page.
My route stays entirely in the Republic. Do I need one?
No. An ETA is only for entering the UK. The Kerry Way, the Dingle Way, the Wicklow Way and the rest of our southern routes don't require one.
Can I apply at the border?
No — and there's no border post to apply at. It has to be done online before you travel.
What if I'm refused?
There's no appeal against a refusal. You'd need to apply for a UK visa instead. If your application is rejected rather than refused, you'll be told why and you can apply again.
Do I need to print it?
No. It's held electronically against your passport. Keep the confirmation email on your phone anyway — it costs nothing to have it.
Does my whole family need one?
Yes, every person travelling, babies and children included. You can apply for them all yourself.
Any doubts, ask us
We'd far rather answer a daft question in March than get a phone call from Belfast in June. If you're unsure whether the ETA applies to you, drop us a line — we'll tell you straight, and if we don't know we'll say so and point you at GOV.UK.
The rules here were checked against gov.uk/eta in July 2026. GOV.UK is always the last word — if anything on this page ever disagrees with it, believe them, not us, and please tell us so we can fix it.
