About

The Cambrian Mountains of Wales contain some of the darkest night skies in Europe. Visit the Cambrian Mountains to discover the constellations and the heritage of galaxies, near and far away and enjoy the Milky Way in all its splendour. Many fascinating species are more active during twilight and overnight. Landscapes familiar to people during the day offer up new insights and excitement as the sun goes down.

A Wealth of Dark Sky Sites

The Cambrian Mountains comprises 467 square miles (1,210 km2) of upland in Mid Wales, far away from cities and sources of man-made light pollution.  With nine easily accessible Dark Sky Discovery Sites and an International Dark Sky Park, there are plenty of options to start your dark sky adventure.

Elan Valley International Dark Sky Park

In 2015, the Elan Valley Estate, situated in the middle of the Cambrian Mountains, achieved International Dark Sky Park status and became the first privately-owned but publicly-accessible park in the world to do so.

Granted the silver tier status by the International Dark Sky Association (IDA) based in Arizona, USA, this means that the entire 45,000 acres of the Elan Valley are protected against light pollution for the benefit of those who live and work there, in addition to our many visitors each year.

The status provides sanctuary for the abundance of wildlife and nature which can be found by day or night on the estate.

Visit the Elan Valley Website for more information.

What is an International Dark Sky Park?

An IDA International Dark Sky Park (IDSP) is a land possessing an exceptional or distinguished quality of starry nights and a nocturnal environment that is specifically protected for its scientific, natural, educational, cultural heritage, and/or public enjoyment. The land may be publicly-owned, or privately-owned provided that the landowner(s) consent to the right of permanent, ongoing public access to specific areas included in the IDA designation.”

As well as Dark Sky Parks there are also Dark Sky Communities, Reserves and Sanctuaries. In Wales we also have the privilege of celebrating Dark Sky Reserves in the Brecon Beacons and Snowdonia National Parks. However, the Elan Valley Estate is the only privately-owned International Dark Sky Park in Wales.
