Another beauty of this area is the Maremma Regional Park, home to the Uccellina Dunes protected area which boasts colourful, lush vegetation of holm oaks, arbutus, mastic trees, pines, cork oaks, myrtle and lavender. Enjoy the changing yellow of broom, and the huge expanses of rosemary, myrtle and lavender. There are many specimens of wild and rare plants, such as dwarf pine - the only native Italian pine - and the equally rare dwarf palm, which make this park a place of singular beauty and a protected area for many animals.
The Ombrone estuary is famous as a meeting point for many birdwatchers. You can see many examples of waders, ducks, herons and egrets and, farther inland, such rarities as the osprey and the flamingo. Towards evening you can come across other animal species such as roe deer in the hills or wild boar in the bush. It is also common to find porcupines, badgers, foxes and the rare otter. On cultivated land north of the mouth of the Ombrone you can admire the wild horses that roam the Maremma, a famous image worldwide.
