During spring, water voles are found living near the National Parks’ biggest lake, there’s trout fishing on the Usk – the Beacon’s largest river, peregrines nesting in an old quarry, there’s an old gunpowder works in a secluded gorge in waterfall country, and on the western fringe of the Park – Wales’ biggest Iron Age Hill Fort.
