Firstly its ace! Its sells old school sweets, you can choose to walk or take the cool train or do both. It is also the longest pier in Europe, I think.
Secondly its famous for Mediterranean Gull as they can be spotted all over it. I saw this stunning 2nd winter bird flying around the pier head - notice the black flecks on its wings and incomplete hood.
Thirdly there's always birds on or around the pier, along with the gulls I spotted 4 Great Crested Grebes on the sea and while I was there I saw reports of mixed divers along the same stretch of sea. I've been in the summer when it is full of Common Tern and Turnstone!
One place not to miss!
