Light pollution has been a real problem for astronomers in the UK. Street lights, industrial estates and motorway illuminations have all made it harder to get a good view of the night sky. But in recent years volunteers and enthusiasts have joined forces with the National Trust, the National Parks and the International Dark Skies Association (IDA) to make stargazing a reality again in many parts of the UK, by reducing lights, or replacing them with non-polluting models.
What and where are the UK's Dark Sky Discovery Sites?
Dark Sky Parks are designated by the International Dark-Sky Association (IDA) as being sufficiently low in light pollution to allow the viewing of exceptionally starry skies. They also offer facilities that promote dark-skies education and appreciation.
The International Dark Sky Association has recognised three large dark areas in the British Isles:
- Galloway Forest Dark Sky Park.
- Sark Dark Sky Island.
- Exmoor Dark Sky Reserve.
In the UK you can visit the Dark Sky Discovery website to browse a map that shows you where you can spot the Orion constellation and places you can even see the Milky Way.
There are 17 Dark Sky Discovery Sites in the UK including many of our nationals parks, such as Exmoor, Brecon Beacons, Northumberland, Peak District, Snowdonia among others. www.nationalparks.gov.uk/visiting/outdoor-activities/dark-skies

Where are the best places for stargazing in the UK?
Your first encounter with dark skies is a truly memorable experience. Away from light pollution, the Milky Way dominates the sky and the familiar constellations are filled with countless stars. But where to go to get the best views? Chris Bramley rounds up the UK's best starry-sky sites.
The Galloway Forest Park was the first area in the country to be recognised for its dark skies, in 2009 and, at 300 square miles, it’s the UK’s largest forest park.
Within easier reach of urban areas in the south, Exmoor National Park got IDA recognition for its dark skies in 2011. Here, moorland and ancient monuments provide a dramatic frame for the stars.
The small Channel Island of Sark has pristine skies with a touch of adventure. Its dramatic coastline offers unblemished views of the stars, thanks to the absence of public lighting and cars (save for a handful of tractors).
From Northumberland National Park and Kielder Water & Forest Park, it is obvious how the Milky Way got its name. Regular stargazing evenings are held in this protected wilderness, with the modernist Kielder Observatory serving as a hub.
The rugged landscape of the Brecon Beacons National Park became a dark sky reserve in 2013. Its sandstone peaks and upland lakes offer a magical setting to discover galaxies.
Elan Valley, deep in the Cambrian Mountains, is the latest area to become a Dark Sky Park. The stars shine bright on this private estate, where the fragile nighttime environment is preserved in all its scintillating majesty.
Allan Bank in a renowned National Trust property at Ambleside in the Lake District and is remote enough that light pollution isn’t an issue.
The Isle of Coll in the Inner Hebrides has no street lighting, meaning its skies are black as velvet. In December 2013 it was awarded Dark Sky Community status, following years of work by the island’s 200-strong community, who carried out an audit of lights and refitted those that spoiled the view for stargazers.
On the North York Moors there are Dark Sky DIscovery Sites at Danby and Sutton Bank park centres, and at Scarborough and Ryedale Astronomical Observatories in Dalby Forest. There are stargazing events at all these sites. There will be a Dark Skies Festival from 9 to 25 February 2018, with stargazing, wildlife and ghost walks, starlight runs, games and activities.
The South Downs National Park became an International Dark Sky Reserve in 2012. Particularly good spots for stargazing are WInchester Science Centre and Planetarium, Old Winchester Hill, Butser Hill, Iping Common, Devil’s Dyke, Ditchling Beacon and Birling Gap.
The Pembrokeshire Coast National Park has worked with the National Trust to establish a network of Dark Sky Discovery sites, and on clear nights it’s possible to see the Milky Way with the naked eye. The National Trust recommends the following sites, which are all car parks or picnic sites, meaning they’re fully accessible; Broadhaven South, Garn Fawr, Kete, Martin’s Haven, Newgale Beach, Poppit Sands, Skrinkle Haven, and Sychpant.
In the Peak District there are Dark Sky Discovery Sites at Surprise View, Parsley Hay and Minninglow, which is beside the High Peak Trail. There are astronomy interpretation panels at these sites to help you explore the night sky and they are changed each season, as different stars and constellations change in visibility depending on the time of year.
Snowdonia National Park was awarded International Dark Sky Reserve status in 2015 for its efforts to prevent and reduce light pollution, thereby protecting the view of the night sky. On a clear night in Snowdonia you can see the Milky Way, all the major constellations, nebulas and shooting stars.
There are four designated Dark Sky Discovery sites in the Yorkshire Dales: at Hawes and Malham National Park Centres, Bucken National Park car park, and Tan Hill Inn.
Wiveton Downs and Kelling Heath Holiday Park in Norfolk are designated ‘two star’ sites - where the seven stars of the Orion constellation and the Milky Way are visible to the naked eye. North Norfolk Astronomy Society hold stargazing events in the local area and a monthly astronomy talk.
How to stargaze
Check the moon phase is before planning your stargazing trip. You’ll see more if you go stargazing before a full moon.
Download a stargazing app - it’ll help you spot stars and constellations more easily. Just be careful not to look at your phone too much as it can reduce your night vision. Try Star Walk (iPhone) or Google Sky (Android). The Stellarium desktop app can be used on a home computer, to plan ahead for your stargazing adventure.
Take a compass to help you orientate yourself when looking at the stars. You can use a compass app on a smartphone instead, but again, looking at bright screens will hamper your night vision.
Once you’re orientated and have identified likely spots for stars turn off any lights and torches and put your mobile away. Your eyes will need about 20 minutes to adjust to the darkness so now’s a good time to have some soup or a hot drink.
What can you see in the sky at different times of year?
Although the stars in the northern sky are visible all year round, it is easier to see certain features at particular times of the year.
In winter look for star clusters, constellations and December’s Geminids meteor shower. In spring the planets are more visible, while in summer there is the Perseid meteor shower. During autumn the Milky Way is more visible and the Orionids meteor shower takes place in October.
What equipment do you need for stargazing?
For stargazing, you simply need to choose your spot and look up. You don’t necessarily need a telescope; even a pair of good 10 x 50 binoculars will let you see the moons of Jupiter and the Andromeda galaxy.
Take a blanket or camping mat to lie on to keep you warm. You’ll be able to enjoy the experience more if you’re not trying to stargaze by craning your neck while standing up.
Bring a torch, but tape a red light filter onto it or use a rear bike light as a torch - red light will affect your night vision much less than a bright white light.
UK astrophotography courses in 2018
For those who want to immerse themselves further in the wonders of the night sky, Dark Sky Destinations is offering its first astrophotography course on Exmoor on the 8th September. The course is entitled “An introduction to nightscape astrophotography”, and will allow budding stargazers the chance to capture some of the spectacular sights that can be seen once the sun sets. www.darkskydestinations.com/
