South Stack, Angleseytop
On the north west tip of Anglesey lies the RSPB reserve of South Stack - where the towering Precambrian cliffs are home to some of the most important sea bird colonies in Wales.

During June and July the sea cliffs here are packed with sea birds - mainy auks including puffin, razorbill and guillemot.
From the cliff tops here you can look down and watch the birds swimming, as they fly underwater in search of fish and sand eels.
During the breeding season up to 3,000 guillemots and 700 razorbills will nest here, precariously balancing their eggs on the narrow ledges.
You'll also find a small puffin colony here and predatory great blacked backed gulls swooping down to grab chicks from any unattended nests.
Ellin's tower up above the sea cliffs
Peregrines also nest in the sea cliffs here and choughs can be spotted feeding in amongst the grass on Holy Island, opposite. The sea cliffs also provide a good vantage point to see porpoise from.
This particular location with its iconic white tower is a great place to watch wildlife from and the RSPB visitor centre here also has telescopes and binoculars for you to use.
Aside from the bird life, South Stack is also famed for it's plant life and one plant in particular, can only found here in the whole of Britain.
The plant in question is known as the spathulate fleawort and is a rather plain yellow flower, not dissimilar to a tall daisy with yellow petals. You'll find it growing along the edges of the sea cliffs here and around the RSPB visitor centre, so tread carefully.
