A range of mountains in South Wales called the Beacons give this national park its name and one of its defining skylines. The scenery in this 520-square-mile park is stunning, with mountains, rolling hills, forests, caves, and waterfalls into its lakes. It is one of the last remaining habitats for wild Welsh ponies, which roam the hills and rugged terrain of the uplands, and the clear skies of the park are dotted with the soaring figures of red kites, which were once endangered. The park contains ancient monuments built by the Romans and the druids, including historic hillforts and stone circles. Brecon Beacons National Park visitors can hike the trails during the day and camp at night to watch the bright stars of the night sky.
