Most of the wildlife here today has colonised the site since it was created in 1990 to mitigate against the loss of Fagbury mudflats as a result of the expansion of the port of Felistowe. There are wonderful views of the Orwell Estuary and it is an unbeatable wetland for its sheer number and species of birds. Visitor Centre. Access on foot. Parking at Station Road, Trimley St Mary near Felixstowe.
