Ise Fjord is a deeply branched arm of the sea into the Danish island Zealand. From its relatively narrow entrance from the Kattegat at Hundested and Rørvig, branches of Ise Fjord stretch 35 km inland and divide the northern part of Zealand into the peninsulas of Odsherred, Hornsherred, and Nordsjælland.
