Your guide to enjoying the night sky in one of the world’s best dark sky locations

Bannau Brycheiniog National Park is an International Dark Sky Reserve – meaning it’s one of the darkest places in the UK and ideal for stargazing. Whether you're camping, glamping or just heading out for an evening walk, this guide will help you make the most of our skies.

What You Might See

• The Milky Way – a glowing arc of stars across the sky (best on moonless nights)

• The Perseids meteor shower – peaking 12–13 August with up to 100 shooting stars/hour

• Planets – depending on the season, look for Jupiter, Saturn or Venus

• Constellations – Orion, Cygnus, Cassiopeia and more

• Satellites & the ISS – bright moving dots that cross the sky silently

Top Stargazing Tips

• Check the weather – clear skies are essential. Use apps like Clear Outside or Met Office.

• Avoid the full moon – darker skies mean better visibility. New moons are best.

• Let your eyes adjust – it takes 15–20 minutes in darkness to see more stars.

• Use a red torch – white light affects night vision. Cover your torch with red cellophane or use a headlamp with red mode.

• Dress warmly – even in summer, nights can be chilly.

• Bring a blanket, mat or reclining chair – for comfort while looking up.

• Be quiet and respectful – keep noise and light to a minimum to preserve the experience for others.
