The Castle Coaching Inn is ideally located for experiencing the dark skies of the Brecon Beacons. The nearby Usk Reservoir is one of the official locations of the Brecon Beacons International Dark Sky Reserve.
Of this list of the top 10 locations in the Brecon Beacons for stargazing, most are within a short drive of Trecastle, with Usk Reservoir being the closest.
