About the reserve

The exposed limestone bedrock forms areas of scree and relic pavement which has grassland with ground flora including the yellow flowering rock rose, wild thyme covered tussocks, wild strawberry and salad burnet. Woodland areas have mature ash, oak and birch with wonderful displays of bluebells and lousewort. Open grassland areas have spring displays of cowslips, bugle and violets. Look out for birds such as redstart, raven and wheatear. At the top of the site, the ancient hill fort affords stunning views of Cribarth and the Tawe Valley.

The site is now managed by grazing under an agri-environment scheme.
