Porth Diana is the smallest Wildlife Trust nature reserve on Anglesey - at 2 hectares it's about the size of a football pitch - and is easily accessible from the road (Ravenpoint Road) and nearby beach

Porth Diana became a nature reserve in 1979, primarily to ensure the protection of Spotted Rock Rose, Anglesey's county flower. The reserve is part of the nationally important coastal heath on the west coast of Holy Island.

Characteristic plants include Bell and Common Heather and low growing Western Gorse and, in the open patches of grassland, you can see wildflowers such as Spring Squill, English Stonecrop and Birdsfoot Trefoil as well as the dainty Spotted Rock Rose itself.
This vegetation helps support a healthy population of invertebrates including Green Tiger Beetle, Meadow and Mottled Grasshoppers and Groundhopper as well as Grayling, Small Tortoiseshell and Small Copper butterflies to name but a few. The dense gorse also supports a number of small heathland birds such as Stonechat, Linnet and visiting Wheatear in Spring.
