Why Is This Route One of the Best Multi-Country Itineraries in Europe?
This London–Edinburgh–Dublin–Ring of Kerry loop packs four of the British Isles' most iconic destinations into a single, logical circuit — and it's genuinely doable in 10 days without feeling rushed. You move from one of the world's great cities to a dramatic medieval capital, then cross to a country famous for its craic, before finishing on one of Europe's most celebrated coastal drives. According to VisitBritain, the UK welcomed over 38 million international visitors in 2023, with London, Edinburgh, and the wider "Celtic Fringe" consistently ranking among the top draws. Ireland's tourism body Fáilte Ireland reports that the Ring of Kerry remains the Republic's single most visited scenic drive, drawing millions of road-trippers each year.
The route works because the logistics are straightforward: a fast train links London and Edinburgh, budget flights or overnight ferries connect Edinburgh (or London) to Dublin, and Kerry is a natural endpoint before flying home from Cork or Kerry Airport. You're crossing two countries — the UK and the Republic of Ireland — so connectivity planning matters. Keep reading for a day-by-day breakdown, practical costs, transport tips, and advice on staying connected across both destinations.
What's the Day-by-Day Itinerary for This 10-Day Trip?
The ideal split is roughly three days in London, two in Edinburgh, two in Dublin, and three days on the Ring of Kerry and Kerry's broader southwest. That gives each destination enough time to breathe without overstaying.
Days 1–3: London
Arrive at Heathrow, Gatwick, or St Pancras (if coming via Eurostar) and get your bearings. London is enormous — the key is to pick neighborhoods rather than try to "do it all."
- Day 1: South Bank walk (Tate Modern, Shakespeare's Globe, Borough Market), then Tower Bridge and Tower of London at golden hour.
- Day 2: Westminster — Big Ben, Parliament, Westminster Abbey, Buckingham Palace, St James's Park. Evening in Covent Garden or Soho.
- Day 3: British Museum in the morning, then a deep dive into a neighborhood: Notting Hill, Shoreditch, or Greenwich. Evening train or flight to Edinburgh.
Practical tip: The London Oyster card or contactless bank card covers all Tube, bus, and Overground journeys — no need to buy separate tickets. A single Zone 1–2 journey costs £2.80 (2026 capped fare). The Heathrow Express from the airport to Paddington takes 15 minutes and costs around £25 one-way; the Elizabeth line is slower (about 45 minutes) but only ~£10.80.
Days 4–5: Edinburgh
The LNER Azuma train from London King's Cross to Edinburgh Waverley takes around 4.5 hours and is one of Britain's great rail journeys. Book in advance on the LNER website for fares as low as £30–£50 one-way.
- Day 4: Royal Mile walk from Edinburgh Castle down to the Palace of Holyroodhouse. Lunch in the Grassmarket. Climb Arthur's Seat for panoramic views of the city — it's a 45-minute hike and completely free.
- Day 5: Scottish National Museum (free), a whisky tasting at one of the Royal Mile distilleries, and the New Town's Georgian architecture. Evening: catch a live folk session at a pub in the Cowgate.
Edinburgh is compact and very walkable. The city's Old Town is a UNESCO World Heritage Site, sharing that designation with the New Town — a rare double listing that underscores just how architecturally significant the city is (UNESCO World Heritage).
Days 6–7: Dublin
Fly from Edinburgh Airport to Dublin (Ryanair and Aer Lingus both operate this route, with flights from around £25–£60 each way, roughly 1 hour 20 minutes). Alternatively, take a coach to Cairnryan and sail with Stena Line to Belfast, then bus to Dublin — a slower but scenic option.
- Day 6: Trinity College and the Book of Kells, then Grafton Street and St Stephen's Green. Afternoon: Dublin Castle and Chester Beatty Library (free). Evening: Temple Bar for live music.
- Day 7: Guinness Storehouse (book tickets in advance, ~€30), Kilmainham Gaol for Irish history, and the Phoenix Park — one of Europe's largest urban parks. Evening: a proper pub crawl along Camden Street or Baggot Street, where locals actually drink.
Note on currency: The Republic of Ireland uses the euro (€), while the UK uses the pound sterling (£). You'll be switching currencies when you cross from Edinburgh to Dublin — keep a small amount of each or use a no-fee travel card.
Days 8–10: Ring of Kerry
Take the early Bus Éireann service or rent a car in Dublin for the drive southwest to Killarney (about 3.5 hours). Killarney is the base for the Ring of Kerry — a 179 km (111-mile) circular route through County Kerry's mountain and coastal scenery.
- Day 8: Drive into Killarney. Afternoon: Killarney National Park, Ross Castle, and the Gap of Dunloe by horse-drawn jaunting car or on foot.
- Day 9: The full Ring of Kerry drive. Go clockwise to avoid tour buses. Key stops: Killorglin (home of the Puck Fair), Cahersiveen, Waterville, Sneem, and Kenmare. Allow 6–8 hours with photo stops.
- Day 10: Morning in Kenmare or Killarney town, then drive to Cork Airport or Kerry Airport for your return flight. Cork has more international connections; Kerry Airport has direct routes to London Stansted and a handful of European cities.
How Do You Get Between London, Edinburgh, Dublin, and Kerry?
Transport is the backbone of this itinerary, and the good news is that every leg is well-served by affordable options.
| Leg | Best Option | Journey Time | Approx. Cost (2026) |
|---|---|---|---|
| London → Edinburgh | LNER train (King's Cross → Waverley) | ~4.5 hrs | £30–£90 advance |
| Edinburgh → Dublin | Ryanair / Aer Lingus flight | ~1 hr 20 min | £25–£80 |
| Dublin → Killarney | Car rental or Bus Éireann | 3–3.5 hrs | €15–€50 (bus) / from €40/day (car) |
| Kerry → Home | Flight from Cork or Kerry Airport | Varies | Varies |
Train vs. flight London–Edinburgh: The train wins on convenience — no airport security, city-centre to city-centre, and a more comfortable ride. Flying saves roughly 2 hours total but adds airport hassle. For most travelers, the train is the better experience.
Renting a car in Ireland: You'll need it for the Ring of Kerry. Public transport reaches Killarney, but the Ring itself is a driving route. International visitors should note that Ireland drives on the left. Car rental costs vary widely; booking in advance through comparison sites typically yields the best rates. Fuel costs roughly €1.75–€1.90 per liter in 2026.

How Do You Stay Connected Across the UK and Ireland?
Staying connected across the UK and Ireland is one of those logistics that travelers often underestimate — until they're standing at a rural Kerry crossroads with no signal and a paper map. The UK and the Republic of Ireland are separate countries with separate mobile networks, so a SIM card that works brilliantly in London won't automatically work seamlessly in Cork without roaming charges or a network switch.
The cleanest solution in 2026 is a travel eSIM that covers both the UK and Ireland on a single plan. A regional eSIM for the British Isles or Western Europe lets you install your data plan before you leave home — no queuing at a phone shop at Heathrow, no hunting for a newsagent in Dublin that stocks the right SIM. You scan a QR code, the eSIM installs in minutes, and you're live the moment your plane lands.
For this specific itinerary, you'll want a plan that covers:
- United Kingdom (England and Scotland) — check out UK eSIM options for current plans
- Republic of Ireland — Ireland eSIM plans cover the whole country including rural Kerry
A Western Europe eSIM is worth considering if you're adding a stopover in Paris or Amsterdam on the way home — one plan covers the whole region without juggling multiple data packages.
Does My Phone Support eSIM?
Most flagship smartphones released after 2020 support eSIM, including all iPhone models from the XS onwards, Google Pixel 3 and later, and Samsung Galaxy S20 and later. The key requirements are:
- Your device must be eSIM-compatible (check your phone's settings under "Mobile Data" or "SIM & Network")
- Your device must be unlocked — carrier-locked phones may not accept a third-party eSIM
- You need an internet connection to scan the QR code and activate (do this at home before you travel)
What About Rural Coverage in Kerry?
This is a fair concern. The Ring of Kerry passes through some genuinely remote terrain — mountain passes, coastal headlands, and valleys with sparse population. Coverage in Kerry has improved significantly in recent years as Ireland's National Broadband Plan has pushed connectivity into rural areas, but you should expect occasional dead zones on the Ring itself, particularly around the Ballaghbeama Gap and the more remote stretches between Cahersiveen and Waterville. Download offline maps (Google Maps or Maps.me) before you set out each morning — it takes about 30 seconds and could save you a very long detour.
What Are the Best Free Things to Do on This Route?
Some of the best experiences on this itinerary cost nothing at all — which helps balance the budget against London's notoriously pricey paid attractions.

When Is the Best Time to Do This Trip?
The best months for this itinerary are May, June, and September. Here's why each season plays out differently:
Spring (March–May)
- Crowds are manageable, especially in April and early May
- Wildflowers on the Ring of Kerry (particularly late April–May)
- London's parks are at their most beautiful
- Temperatures: London 10–16°C (50–61°F), Edinburgh 8–13°C (46–55°F), Kerry 10–15°C (50–59°F)
- Rain is possible everywhere — pack layers
Summer (June–August)
- Peak season: longest days, warmest weather, but also peak crowds and prices
- Edinburgh in August means the Fringe Festival (the world's largest arts festival) — extraordinary but accommodation prices triple
- Ring of Kerry is busy with tour coaches in July–August; start early (before 9am) to beat them
- Temperatures: London 18–24°C (64–75°F), Edinburgh 15–19°C (59–66°F), Kerry 16–20°C (61–68°F)
Autumn (September–October)
- September is arguably the sweet spot: summer crowds have thinned, prices drop, and the light in Kerry is golden
- October brings more rain but also the dramatic Atlantic storms that make Kerry's coast look truly wild
- Edinburgh's Fringe is over; the city returns to its quieter, more authentic self
Winter (November–February)
- Not recommended for Kerry (many guesthouses close, some roads are treacherous)
- London and Edinburgh are fine year-round, with Christmas markets adding charm in December
- Shortest days — you'll lose light fast for photography
What Should You Pack for This Itinerary?
Packing for a trip that spans urban sightseeing and a remote coastal drive requires some thought. The weather across the UK and Ireland can change within a single afternoon.
Essentials:
- A waterproof jacket (non-negotiable — this is the British Isles)
- Comfortable walking shoes for city days AND sturdy shoes or light hiking boots for Arthur's Seat and the Ring of Kerry
- Layers: a fleece or mid-layer works year-round
- A small daypack for daily use
- Universal plug adapter (UK uses Type G three-pin plugs; Ireland uses the same)
- Both £ and € in cash, or a no-fee travel card (Wise, Revolut, and Charles Schwab are popular choices)
Tech:
- Your eSIM-compatible phone with a Simology travel eSIM pre-installed
- Portable power bank (especially for long driving days in Kerry)
- Offline maps downloaded for the Ring of Kerry
- Camera or phone with a good camera — Kerry's light is extraordinary
FAQ
Do I need a visa to visit both the UK and Ireland?
Most travelers from the US, Canada, Australia, and New Zealand can enter both the UK and the Republic of Ireland visa-free for up to 6 months (UK) and 90 days (Ireland) respectively. EU/EEA citizens can enter both freely. However, the UK and Ireland are not part of the Schengen Area, so each country has its own border. You'll typically clear UK immigration when you arrive in London and Irish immigration when you land in Dublin — both are generally straightforward for visa-free nationals.
Is a travel eSIM better than buying local SIM cards in each country?
For a trip spanning two countries like this, a travel eSIM is almost always more convenient than buying separate local SIM cards. With a local SIM, you'd need to find a store, show ID, wait for activation, and then repeat the process in Dublin. A travel eSIM installs before you leave home, covers both the UK and Ireland on one plan, and lets you keep your home number active on your physical SIM at the same time.
How much data do I need for 10 days in the UK and Ireland?
Most travelers on a 10-day trip use between 3GB and 8GB of data, depending on how heavily they stream and use navigation. If you're using Google Maps for the Ring of Kerry drive, streaming music, and occasionally video calling home, budget for at least 5GB. Downloading offline maps before each driving day reduces data consumption significantly. A 10GB plan for the full 10-day trip is a comfortable buffer for most travelers.
Can I drive on the Ring of Kerry with a US or international driver's license?
Yes — both the UK and Ireland recognize US, Canadian, Australian, and most international driver's licenses for short-term visitors (up to 12 months). You'll drive on the left in both countries. Car rental companies may require you to be at least 23–25 years old and may charge a young driver surcharge for under-25s. An International Driving Permit (IDP) is not legally required in Ireland or the UK for most nationalities, but some rental companies request one — check with your specific rental company in advance.
How do I get from Dublin to Killarney without a car?
Bus Éireann operates direct services from Dublin Coach Station (Busáras) to Killarney several times daily. The journey takes approximately 3.5–4 hours and costs around €15–€25 one-way when booked in advance at Bus Éireann's website. Irish Rail also runs from Dublin Heuston to Killarney (with a change at Mallow), taking around 3.5 hours. Once in Killarney, you'll need to rent a car, hire a driver, or join a guided tour to explore the Ring of Kerry properly.
Is the Ring of Kerry safe to drive independently?
Yes, the Ring of Kerry is very safe to drive independently — it's a well-maintained public road, not a challenging off-road track. The main hazards are tour coaches (which travel counterclockwise, so go clockwise to avoid meeting them head-on on narrow sections) and slow-moving agricultural vehicles. Some sections near the coast are narrow with passing places. Drive at a relaxed pace, pull over frequently for photos, and give yourself a full day (6–8 hours) to complete the circuit without rushing.
What's the best way to get from London to Edinburgh?
The LNER train from London King's Cross to Edinburgh Waverley is the most popular and most enjoyable option. Advance tickets booked 6–8 weeks ahead cost £30–£50; walk-up fares can exceed £150. The journey takes approximately 4.5 hours and runs multiple times daily. Flying is faster in the air but slower door-to-door once you factor in airport transfers and security. Budget airlines (easyJet, Ryanair) fly London–Edinburgh from around £25 advance, but the train is the greener, more comfortable choice.
Does my phone work in rural Kerry?
Coverage in rural Kerry has improved significantly but is not universal. You'll have solid 4G signal in Killarney town, Kenmare, Cahersiveen, and most villages on the Ring. Expect intermittent or no signal in the mountain passes and some remote coastal sections. Download offline maps (Google Maps allows this for free) before each day's drive. A travel eSIM connects to the strongest available local network, which helps maximize coverage in fringe areas compared to relying on a single home-carrier roaming agreement.
Your 10-Day British Isles Adventure Awaits
This London–Edinburgh–Dublin–Ring of Kerry circuit is one of those itineraries that genuinely delivers on its promise. You'll stand on the ramparts of Edinburgh Castle watching the sun set over the Firth of Forth, walk the cobblestones of Temple Bar to the sound of a fiddle drifting out of a pub, and pull over on a Kerry clifftop to watch Atlantic waves crash against rocks that have stood for 400 million years. Ten days feels short, but the route is tight enough that you won't waste time backtracking.
The practical details — transport, costs, and connectivity — are all manageable with a bit of advance planning. Book your London–Edinburgh train early for the best fares, sort your Dublin flights in advance, and get your rental car reserved for Kerry before you leave home. And before any of that: install a UK eSIM and an Ireland eSIM — or a single Western Europe plan — so you step off the plane at Heathrow already connected, and stay that way all the way to your last Kerry sunset.
