Where to stay

An International Dark Sky Reserve, the Brecon Beacons is brilliant for stargazing. A stone’s throw from Pen y Fan, Camp Cynrig Glamping Village offers eco-friendly accommodation from which to view the Milky Way on a clear night. Book a boutique bell tent, complete with double bed and solar-powered appliances (from £200 for a weekend; breconglamping village.co.uk). For solid walls, Llwyn Celyn (above) is a medieval hall house with original features and spectacular views (four nights from £964; landmarktrust.org.uk).
