Rules in force · 8Non-EU visitors get 90 days in any rolling 180-day window…
- Europe ↗Non-EU visitors get 90 days in any rolling 180-day window, counted across all 29 Schengen states together — not per country; the Entry/Exit System now logs each crossing, so an overstay is detected automatically.
- Europe ↗On the first Schengen entry since EES began, non-EU travellers give four fingerprints and a face photo at the border instead of a passport stamp; there is nothing to apply for or pay in advance.
- Britain and Ireland ↗Neither the UK nor Ireland is part of Schengen: days spent here do not count towards the 90/180-day Schengen limit, and a Schengen visa does not admit you to either country.
- Britain and Ireland ↗The island of Ireland runs on two currencies: euro in the Republic, pound sterling in Northern Ireland and Great Britain. Carry a card that pays in both without fees.
- Britain and Ireland ↗Both islands drive on the left. Speed limits are in miles per hour in the UK (including Northern Ireland) and in kilometres per hour in the Republic of Ireland.
- United Kingdom ↗Most visitors who do not need a UK visa now need an Electronic Travel Authorisation (ETA) before travelling; this includes EU nationals. Irish citizens are exempt. Check the UK government site for your passport.
- United Kingdom ↗The UK is outside the EU and the Schengen area; a Schengen visa is not valid for the UK.
- United Kingdom ↗Driving is on the left; London has congestion and emissions charges for most vehicles, so do not drive in the city.

The Mournes are not a national park: no gate, no fee, no park authority. They are an Area of Outstanding Natural Beauty, a farmed and inhabited upland of granite, heather and drystone walls, with Northern Ireland's highest summit — Slieve Donard at 850 m — reachable on foot from a street in Newcastle in about two hours. The range runs roughly 20 km from Newcastle to Rostrevor, most of it between 500 and 650 m, so the days are hill days rather than mountaineering: boots, a map and waterproofs, and a plan for the weather, which arrives fast. Access is open on foot across farmland and the National Trust's ground; you pay only for parking, buses and the reservoir valley. A car makes the southern trailheads at Annalong and the Silent Valley far easier, but Belfast and Newry both have direct buses to Newcastle, so a summit day is possible without one. The main hazard is not altitude but road traffic on narrow approach roads, plus bog, erosion and cloud on the tops.

Time out
Finding the local time zone…
Times are local to the spot (zone loading). The half-hour margin is our rule of thumb, not an official figure; light fades earlier in forest or under cloud. Carry a headlamp on any route that could run late.
Accessibility
- The Silent Valley reservoir track is firm and largely level, suitable for wheels with assistance.
- Donard Park, the lower Granite Trail and the coastal paths at Bloody Bridge and Annalong give short, low-gradient walks.
- The high summits are steep, eroded and often boggy; not suitable for limited mobility.
Visiting lightly
- Stay on established paths; the granite and peat soils erode quickly and repairs are slow.
- Take everything out — there are no bins above the trailheads.
- Use the bus from Belfast or Newry for Newcastle rather than adding a car to already full weekend car parks.
- Buy food and fuel in Newcastle, Annalong or Kilkeel so the villages keep the benefit of hill traffic.
Questions people ask
How much does it cost to enter Mourne Mountains?
Nothing. There is no gate, no permit and no park fee — the Mournes are an Area of Outstanding Natural Beauty, not a national park. You pay only for parking, typically a few pounds a day at Donard Park or Carrick Little (2026 estimate), and for buses.
What are the best hikes in Mourne Mountains?
Slieve Donard via the Glen River from Donard Park is the classic: about 5 km each way, 4 hours return, steep and muddy near the top. Bloody Bridge and the Brandy Pad is longer and more scenic. Slieve Binnian from Carrick Little is a roughly 11 km triangular walk over the Silent Valley. The Silent Valley reservoir track is the easy option.
When is the best time to visit Mourne Mountains?
May, June and September: long daylight, firmer ground and fewer people than July and August. Fine summer weekends bring heavy traffic and full car parks, so arrive before 10:00 or come on a weekday. Winter days are short and the tops can be icy.
Do I need a guide to climb Slieve Donard?
No. The Glen River path from Donard Park is signed and straightforward for anyone with boots and reasonable fitness. Take a map and waterproofs; cloud can hide the route and the upper path is eroded.
Can I get to the Mournes without a car?
Yes. Regular buses run from Belfast to Newcastle, and from Newry to Newcastle, Warrenpoint, Rostrevor and Kilkeel. A seasonal rambler bus circles the mountains from Newcastle. A car makes the Annalong and Silent Valley trailheads much easier.
Is the Mourne Wall walk doable in a day?
It is about 35 km over 15 summits and takes most fit walkers 10–12 hours. Start at first light, carry all your water and plan a bail-out. There is no shelter or water on the route.
