Baaiduinen is a village on the Frisian Wadden Sea island of Terschelling in the Netherlands. It had a population of 106 in January 2017.[1]
Baaiduinen is surrounded by the much older hamlets of Kinnum, Kaart (Kaard) en Horp. Baaiduinen is the youngest village on Terschelling and has only been recognized as a separate settlement in the 19th century. North of Baaiduinen is a polder landscape named het Hoge Land ("the highlands").
Tourism has replaced dairy farming as the main source of income and most farms have been rebuilt to accommodate tourists.
