Cosmos Camping is a small, highly regarded campsite nestled in the Bannau Brycheiniog (Brecon Beacons) hills near Afon Clydach, just off the A4069 past the Black Mountain Quarries.

The site sits within one of only 18 International Dark Sky Reserves in the world, making it a prime spot for stargazing — on clear nights, campers can observe the Milky Way, major constellations, nebulae, and meteor showers.

The campsite was established by owners Bob and Alex, who relocated from near London during the pandemic and shaped the surrounding land into what they describe as a place of extreme beauty and calm. Dogs and raised charcoal BBQs are welcome.

An on-site licensed horsebox bar called The Firepit operates Wednesday through Sunday, and a food truck known as The Bear Pit makes regular Saturday appearances.
