It's amazing what you can see in the dark
And truly dark skies - like those you'll find in many of our national parks - allow us to see far-off stars and galaxies in the same way our ancestors did, without the orange glow of street lights and neon signs.
Next time you're visiting one of the 15 National Parks to enjoy our great outdoors, why not stay a while to admire the night sky in all its stellar glory. We're working to set up Dark Sky Reserves, Dark Sky Parks and Dark Sky Discovery Sites and to help run special events to show everyone the wonder of our night skies.
We're especially proud that of 13 International Dark Sky Reserves in the world, the UK has four in National Parks - Brecon Beacons, Exmoor, Snowdonia and South Downs. We've also home to two International Dark Sky Parks - Northumberland National Park and Kielder Water & Forest Park, and Tomintoul and Glenlivet in the Cairngorms National Park.
