Brecon Beacons National Park was officially certified as an International Dark Sky Reserve by the International Dark-Sky Association (IDA) in 2013 — one of only 18 such reserves worldwide and the premier stargazing destination in the UK. Far from urban light pollution, the Milky Way arch, Andromeda Galaxy and Perseid meteor showers (up to 100 meteors per hour) are all visible to the naked eye. From setting up a telescope on the flat car park at Usk Reservoir, to gazing at the stars beneath the thousand-year-old ruins of Llanthony Priory, to exploring deep-sky objects with professional astronomers at the observatory — this is the place that inspired Coldplay to write Yellow, and the cosmic theatre of every stargazer's dreams.
Explore ten top stargazing sites including Usk Reservoir, use professional telescopes at the observatory to explore deep space, and gaze at the Milky Way beneath the thousand-year-old ruins of Llanthony Priory
Arrive at Usk Reservoir in the late afternoon — the most renowned dark sky stargazing site in the Brecon Beacons, with a limiting magnitude of 6.4, and a flat car park perfect for setting up a telescope. After nightfall, the Milky Way arch is visible to the naked eye spanning the sky; in summer you can capture the Perseid meteor shower (up to 100 meteors per hour). The next day, head to the observatory at the National Park Visitor Centre (Libanus), where professional astronomers will guide you through observing Jupiter's moons and the Andromeda Galaxy using a 10-inch SCT telescope. In the evening, drive to the ruins of Llanthony Priory, gazing at the stars against the silhouette of the thousand-year-old Norman architecture, feeling the vastness of the cosmos and the depth of time. If your visit coincides with the Wales Dark Sky Week in February or the Dark Sky Festival in September, you can also attend astronomy lectures and guided stargazing sessions.
A countryside restaurant just a 10-minute drive from Usk Reservoir, awarded a Michelin Green Star in 2023, renowned for ingredients from its own organic kitchen garden. The Sunday roast features slow-roasted beef from local pastures with Yorkshire pudding — the warmest comfort after a night of stargazing. Enjoy hot Welsh lamb chops by the winter fireplace, with the dark sky horizon of the Brecon Beacons visible through the window. Advance booking strongly recommended; tables are hard to come by in peak season. Average £25-45 per person.
A medieval coaching inn built in 1432, with low wooden beams and roaring fireplaces, steeped in historical gravitas. Their Welsh Rarebit uses beer brewed with local Brecon malt to create the sauce — widely regarded as the best in the region. After dinner, a 20-minute drive takes you to Hay Bluff to begin your stargazing — the perfect "dinner + stars" combination. Average £18-30 per person.
A popular Nepalese restaurant in Brecon town, famous for its authentic momo dumplings (steamed or fried) and spicy curries. For travellers returning from stargazing at Llanthony Valley, a steaming bowl of Dal Bhat (lentil soup with rice) is the perfect meal to replenish your energy. Located conveniently near the Visitor Centre direction for easy dining en route. Average £12-20 per person.
A local craft beer and gin tap room in Brecon, run by the Antur brewery, serving freshly tapped Welsh craft beers and Cascave Gin tastings. After a night of stargazing, unwind with a locally brewed Pale Ale and reflect on the magnificence of the Milky Way. Light snacks are available on site, with a relaxed and friendly atmosphere. Average £10-18 per person.
