About

South Stack is a reserve where rolling heathland and farmland meet rugged and rocky sea cliffs. Facing South Stack island and the Irish Sea beyond, the cliffs are a vital breeding ground for Guillemots, Razorbills and Puffins in spring. The rare Chough can be seen swooping along the cliffs all year round.

This Anglesey reserve is home to Ellin’s Tower, a bright white Victorian building that looks a little like a castle. It looks out across the cliffs, down to the lighthouse which stands watch over the seas.
