Discover Dorset's dark skies

As the summer comes to an end and the clocks go back it isn’t all doom and gloom, as it means we can look forward to incredible night viewing opportunities to see astronomical sights.  

Dorset's open skies

With over half of Dorset being an Area of Outstanding Natural Beauty (AONB) and with many national parks, the county’s big open skies are perfect for seeing stars all year round. The clear dark skies of autumn and winter makes this the prime viewing season.  

Dorset is fortunate to have low levels of light pollution which is one of the main issues for astronomers. There are locations throughout the county where visitors can experience incredible dark skies. There are dark sky events throughout the year, including stargazing evenings and talks, so why not join one on your visit and learn something new.  

Dark Sky Reserve

One of the best places for dark skies in Dorset is Cranborne Chase AONB. In 2019 Cranborne Chase became the first Area of Outstanding Natural Beauty in the country to be designated in its entirety as an International Dark-Sky Reserve. With only 17 International Dark Sky Reserves in the world, it is one of the best places in the country for stargazing.  On a clear night you can see thousands of stars, the Milky Way and the Andromeda galaxy, which is over 2.5 million light years away!  

So, whether you’re a complete beginner or the next Professor Brian Cox, start your Dorset dark skies adventure. You'll be over the moon with what you discover.  

  • Dark Skies are everywhere, but unfortunately for many, the beauty of them is obscured by light pollution. Dark Sky Reserves or anywhere with ‘Dark Skies’ are areas that are minimally affected by Artificial Light at Night (ALAN). This not only makes the starry sky more visible, but it is also much better for wildlife and for human health: Nature needs the night!

  • Dorset has some of the darkest skies in southern England. You can see this clearly by looking at the light pollution map. It also has some fantastic stargazing locations which include beautiful landmarks, historical features and coastal areas which really do add something to your average stargazing evening.

  • The sky is darkest from about 2 hours after sunset to 2 hours before sunrise. You get the most amazing starry nights during the summer, if you stay up late enough, but stargazing over the winter months once the clocks have gone back makes it a truly family affair. Different seasons also have different highlights:


    Autumn – Milky Way (our galaxy)

    Winter – Sparkling star clusters

    Spring – Distant galaxies

  • Anywhere you are away from artificial lights once the sun’s gone down. The show the night sky puts really takes your breath away on a clear night. The darkest skies are those of Cranborne Chase AONB International Dark Sky Reserve but much of Dorset, away from artificial light can be just as impressive. Gardens also offer a good option if you’re lucky enough to live or be staying somewhere dark!

  • Your eyes! Seriously, from a dark site you can see an enormous amount without any optical aid, just as everyone did before the invention of the telescope in the 16th Century. If you like, try binoculars; you’ll be astounded at how much more you can see: craters on the Moon, star clusters, distant galaxies, and many, many more stars. We would also recommend warm clothes, hot chocolate and marshmallows and something to lie on. A deckchair is great as you’re comfy and you won’t get a sore neck.

  • For desktop and laptop computers, Cranborne Chase Dark Sky Reserve recommends Stellarium. It’s free and exceptionally powerful . For Android or iOS devices, they recommend Sky Safari or Stellarium Mobile (Android Only).

  • It’s a good idea to visit your intended stargazing location during daylight, so you can be aware of any potential hazards and to make sure that the location allows access at night. If you feel nervous about being out alone in the dark, go with a friend or join an organised event.  Make sure you know how all your equipment works beforehand, and check it over to ensure that nothing is faulty. Make sure you put any potential trip-hazards out of the way (e.g. between tripod legs).
