The park is home to a wide selection of animals and birds and the special hide at the end of the salt marsh trail. There is a diverse range of flora and fauna in the park ranging from blackberry and bramble in the oak forest to water lilies which thrive in a fen area near Lough Lilly to orchids on the sand dunes. There are small areas of semi-natural woodland comprising trees such as oak, ash and birch giving you the feel of primeval woodlands in Ireland.
