Quite expensive, but I bought a season ticket for the Swannery and Gardens. Really great place though and it's awesome seeing the cygnets at the moment ^.^
Abbotsbury Swannery is home to the only managed colony of nesting Mute Swans in the world. Visiting here is one of the best things to do in Dorset. At 12 noon & 4pm daily, you can help hand-feed 600 swans. Plus: Dorset’s largest willow maze, swinging nests play area, café, gift shop, free parking.
