As a higher-laying part of the very northern Wadden Sea, the mouth of the Varde River is one of the last places that gets flooded by the rising tides. In combination with the fresh water streaming out of Varde River, the mouth and and the immediate surrounding area is one of the best places in Ho Bay for watching waterbirds. In season, there is a concentration of birds, especially in rising tides and many thousands of waterbirds flock in the shallow waters or on the muddy flats. The area is know for high numbers of Eurasian Spoonbill, Common Shelduck, Northern Pintail and Avocet. The surrounding grassland hosts a variety of birds, including pipits, wheatears and warblers and the area have also hosted vistits of rare vagrants such as Hudsonian Godwit, Greater Short-toed Lark and Black-headed Bunting.
Access to the good observation point are best on the east coast of Ho Bay from the paved road - see the map.
