The Duer ornithological reserve is an old salt pan now inhabited by tens of thousands of birds. From the two hides installed occasionally, it is possible to observe specimens throughout the year.

In winter, geese and teal replace the stilts and terns that camp there in the summer. Observatory number 1 is located a little further east of the salt pan.

The observatory is a beautiful wooden tower where you can observe many species of birds. The windows inside are unfortunately dirty with time.

Nice observation tower but not very suitable for telescopes. Binoculars are preferable. The windows are in the way but avoid disturbing the wildlife and protect from the rain. The Duer is also a walk along the gulf on the waters of which many migratory birds, among others, meet. Too bad we can't put some very recent photos here.
