The UK has 22 certified International Dark Sky Places: seven Reserves, seven Parks, six Communities and two Sanctuaries. That is more than any country outside the United States. This page lists all of them with their correct designation and the year each was certified, checked against DarkSky International's own register rather than copied from other guides.
Most lists you'll find are out of date, and nearly all of them get at least one designation wrong. Two were certified after 2024, and one of the best-known sites is routinely described as something it isn't.
International Dark Sky Reserves (7)
A Reserve has a dark core surrounded by a populated buffer zone, where lighting policy protects the core. They're created by partnerships between multiple landowners, which is why they tend to be National Parks.
| Place | Nation | Certified |
|---|---|---|
| Exmoor National Park | England (Somerset & Devon) | 2015 |
| Bannau Brycheiniog National Park (Brecon Beacons) | Wales | 2015 |
| Eryri National Park (Snowdonia) | Wales | 2015 |
| Moore's Reserve, South Downs National Park | England | 2016 |
| Cranborne Chase | England (Dorset, Hampshire, Wiltshire) | 2019 |
| North York Moors National Park | England | 2020 |
| Yorkshire Dales National Park | England | 2020 |
Exmoor was the first Dark Sky Reserve in Europe. Bannau Brycheiniog was the fifth in the world and the first in Wales. Cranborne Chase was the first National Landscape โ what used to be called an AONB โ to earn Reserve status.
A note on names. The South Downs reserve is officially Moore's Reserve, named after Sir Patrick Moore. Bannau Brycheiniog and Eryri are the Welsh names now used officially for the Brecon Beacons and Snowdonia; both are still widely searched under the English names.
International Dark Sky Parks (7)
A Park is a publicly or privately owned space, protected for conservation, with good outdoor lighting and public dark sky programmes.
| Place | Nation | Certified |
|---|---|---|
| Galloway Forest Park | Scotland (Dumfries & Galloway) | 2015 |
| Northumberland National Park & Kielder Water & Forest Park | England | 2015 |
| Elan Valley Estate | Wales (Powys) | 2015 |
| Bodmin Moor Dark Sky Landscape | England (Cornwall) | 2017 |
| Tomintoul & Glenlivet โ Cairngorms | Scotland | 2018 |
| OM Dark Sky Park & Observatory | Northern Ireland (Davagh Forest) | 2020 |
| West Penwith | England (Cornwall) | 2021 |
Here's the one nearly everyone gets wrong. Bodmin Moor is called a Dark Sky Landscape โ that's its name โ but it is designated an International Dark Sky Park. "Landscape" is not a DarkSky designation tier. If you see a list describing Bodmin Moor as a Reserve, or presenting "Landscape" as a fourth category alongside Park and Reserve, that list wasn't checked.
Northumberland is the UK's flagship. It's a Gold Tier park โ the highest classification, reserved for the darkest skies โ and it combines two separate parkland units, which was a first for the programme. It's also the most accessible genuinely dark sky in England for anyone in the north.
OM Dark Sky Park at Davagh Forest was the first International Dark Sky Place certified in Northern Ireland.
International Dark Sky Communities (6)
Communities are towns, villages and islands where residents have collectively changed their lighting. These are the hardest to achieve, because they need people to agree.
| Place | Nation | Certified |
|---|---|---|
| Coll | Scotland (Inner Hebrides) | 2015 |
| Moffat | Scotland (Dumfries & Galloway) | 2016 |
| North Ronaldsay | Scotland (Orkney) | 2021 |
| Presteigne & Norton | Wales (Powys) | 2024 |
| Gower National Landscape | Wales | 2025 |
| Thorington Street | England (Suffolk) | 2026 |
Moffat was the first town on the British mainland to achieve Dark Sky Community status, after replacing more than 600 street lights with downward-directed fittings.
Thorington Street in Suffolk was certified in February 2026 and is the first Dark Sky Community in England. A hamlet. This is the newest UK designation, and it's why any list published before this year is incomplete.
Gower was certified in January 2025 as the first National Landscape in the UK to become a Community rather than a Reserve or Park.
International Dark Sky Sanctuaries (2)
Sanctuaries are the most remote and often the darkest places, where the conservation position is most fragile. The designation exists partly to raise awareness of sites too isolated for much public outreach.
| Place | Nation | Certified |
|---|---|---|
| Ynys Enlli (Bardsey Island) | Wales | 2023 |
| Isle of Rum | Scotland (Inner Hebrides) | 2024 |
Both need a boat. Rum was Scotland's first Sanctuary. Ynys Enlli, off the tip of the Llลทn Peninsula, is home to the Bardsey Bird and Field Observatory and has a population you can count on your fingers.
What about Sark?
Sark is frequently listed as a UK dark sky place. It was the world's first Dark Sky Island, certified in 2011, and it's genuinely worth visiting.
But Sark is a Channel Island โ a Crown Dependency, not part of the United Kingdom โ which is why it doesn't appear on DarkSky International's UK register and isn't counted in the 22 above. Worth knowing if you're being precise, and worth visiting regardless.
Which one should you actually go to?
The honest answer depends far more on how far you're willing to drive than on which site is darkest.
If you want the darkest sky reachable by car: Galloway Forest Park or Northumberland. Both are Gold Tier or close to it, both have proper facilities, and both are within a few hours of the major northern cities.
If you're in the south: Cranborne Chase and Moore's Reserve are the practical choices. Neither will match Galloway, but a Bortle 4 sky ninety minutes away beats a Bortle 2 sky you never drive to.
If you want a guided introduction: Kielder Observatory in Northumberland and OM Observatory at Davagh both run public sessions with telescopes and someone who knows how to point them. For a first proper night out, this is a much better use of an evening than standing in a field wondering what you're looking at.
If you want to combine it with a holiday: Exmoor and the Yorkshire Dales have the best supporting infrastructure โ dark-sky-friendly accommodation, telescope hire, and annual festivals.
If you want to say you've been somewhere nobody else has: Ynys Enlli or Rum. Bring everything you need and check the boat.
The thing that matters more than the designation
A certified dark sky place is a guarantee about lighting policy, not about tonight.
Three things will do more for what you actually see than which site you pick:
Cloud. In the UK this is the dominant factor by a wide margin. A Bortle 5 sky with no cloud beats a Bortle 2 sky with cloud, every single time. Check the forecast, and specifically check for high thin cirrus, which ruins astronomy while looking like a clear night to everyone else.
The Moon. A full Moon washes out the sky as thoroughly as a small town. Check the phase before you commit to a two-hour drive. The nights either side of new Moon are what you want โ which is exactly why the Perseids in August 2026 are worth planning around.
Your own eyes. Full dark adaptation takes twenty minutes and keeps improving for up to forty. One glance at a phone screen resets it. This is free, and most people skip it.
What to take
Learned the hard way:
- Far more clothing than the temperature suggests. You'll be standing still in the dark for two hours. Clear nights are the cold ones. Hat, extra layer, gloves you can still work with.
- A red torch, or red cellophane over a normal one. White light destroys your night vision and everyone else's, and at a public site it will make you unpopular very quickly.
- Something to lie on or in. A reclining chair changes everything if you're looking up for any length of time.
- A flask. Not optional in February.
- Binoculars before a telescope. A cheap pair of 10ร50s will show you more on a first night out than an unfamiliar telescope you're still learning to aim.
- Somebody else. Partly for safety on unlit moorland, partly because it's better shared.

We keep this list current. Two designations have been added since 2024 โ Gower in January 2025 and Thorington Street in February 2026 โ and more UK sites are in the application process.
If you spot something out of date, or you know a site we've got wrong, tell us. We'd rather be corrected than be one of the guides still saying there are twelve.
