Stargazing in Cardiff, UK
Cardiff's Bortle 6–7 skies benefit from quick access to the Brecon Beacons National Park, a designated International Dark Sky Reserve just 40 minutes north — one of only a handful in the world. The park's Bortle 2–3 skies make it outstanding for deep-sky observing. South Wales' coastal position means Atlantic weather systems move through regularly, but clearances behind cold fronts are often superb. The southern horizon is unobstructed toward the Bristol Channel, making it good for low-declination targets.
