The conditions of the sea of Kattegat differs a lot from those by the North Sea. The west coast can be rough, with high winds and waves, whereas on the east coast you will often find calm seas and shallow waters, perfect for the family holiday. With the shallow waters and tide, you will often find small islands emerging from the water, so you can have your very own private island for a short while. See the overview of the blue and white flags on the beaches of North Jutland.
I you like an exotic twist on your holiday, then look no further than Frederikshavn where you can find the only palm beach in Denmark. Each year 100 palm trees from China and the Canary Islands are planted along the beach. Furthermore, there are lifesavers on the beach and beach volley and beach football fields.
In Øster Hurup there is a child-friendly beach due to calm water. There are good parking options and toilets.
Sæby is also offering a slightly different beach experience because here you can walk along the two kilometer long seaside promenade. Here it is also interesting to explore what the sea flushes up. You can for instance find red conches, razor clams, tower shells and when the wind is blowing from southeast it is possible to find amber.
