Being the highest peak in South Wales, it’s no wonder that one of the most common questions we get asked, is how high is Pen Y Fan. The highest point on Pen Y Fan is 886 metres (2,907 ft) above sea-level. To mark the highest point on the summit, there is a summit sign that has been placed by The National Trust.
People often climb the nearby summit of Corn Du, which is 873 m (2,864 ft) above sea-level. A very close level of height, making it the second highest peak in South Wales.
