Elan Valley

The Elan Valley and the surrounding Cambrian mountains offer some of the darkest skies in Wales and give you an immense sense of being remote, out in the wild and connected with nature. 

The Elan Valley is a recognised International Dark Sky Park, and the Cambrian Mountains have lots of dark sky discovery sites with easy access locations where you can go and gaze at the night sky.  Six of those dark sky discovery sites are connected by an asteroid tourism trail, which makes for a really fantastic adventure.

Snowdonia (Eryri)

For rugged landscapes under the stars, Snowdonia is the place to go. 

You just can't beat the view of those epic mountains stretching up to touch the stars or the sight of the Milky Way reflecting in the glacial lakes below.

Snowdonia can be a pretty dangerous place if you don't have the necessary skills or competence. Be sure to contact one of the local mountain guides there to help you out. But that said, there are plenty of lay-bys and parking spots where you can just pull up, get out and just enjoy the stars.

Anglesey (Ynys Môn)

Anglesey offers one of the best places in Wales to see the Northern Lights across the winter months. 

You may also be lucky enough to catch a display of bioluminescent plankton. There are a number of beautiful lighthouses on Anglesey, and where there's a lighthouse, it's probably a dark place. The view out across the Irish Sea is untarnished by light pollution. You get to see amazingly dark skies.

Brecon Beacons

The Brecon Beacons Dark Sky Reserve holds a special place in my heart because it's where I first fell in love with the night sky and got into astrophotography and astronomy. It has such a varied landscape with mountains, hills and folded valleys, waterfalls, rivers, lakes, reservoirs. There's just something for everyone. 

Some easy to access locations include Llangorse lake, Usk Reservoir and the Brecon Beacons Visitor Centre. I've even been lucky enough to see the northern lights from as far south as the Brecon Beacons.

Gower coast

The Gower Coast offers some of the best beaches in the world, surrounded by very characterful limestone cliffs. 
The view out across the Bristol Channel is untarnished by light pollution, and it's one of the best places in Wales to stare into the core of our galaxy, the Milky Way. 

If you're lucky, it's another good place to spot the bioluminescent plankton. The sight of the waves crashing and lighting up with electric blue is just one of the most magical things that you could possibly experience. 

These five places all offer an amazing mixture of varied landscapes, coastal regions and mountain regions, but there are plenty more dark sky destinations to go stargazing in Wales.
