Kongernes Nordsjælland, or in English - the North Zealand of Kings, is a National park in the making in Nordsjælland, Denmark. The National Park status has yet to take full effect, but the necessary law passed through parliament in 2008, and protection will be effective from sometime in 2009.
A large portion of the national park is taken up by Gribskov, Denmarks 4th largest forest, covering some 5600 hectares (ca 14.000 acres), the landscape here is undulating with varied vegetation, but mostly pine, beech and some majestic old oak trees.

Flora and fauna
While not exactly rich on fauna by most standards, for a densely populated area like Denmark - and Zealand in particular, the range of animals to be spotted here is as richer than most everywhere else in the country outside the wadden sea. Mammals living in the park includes many species of deer (red-, roe-, fallow- and sika deer) which constituted a large part of the royal interests in the northern forests. You can also see foxes as well as the European Badger, and if you are extremely lucky you can sometimes spot Osprey or the White Tailed Eagles, but more common sightings up in the air includes the Common Buzzard and to some extend the Honey Buzzard and Sparrow Hawk.
There are no fees to enter the park, and the only fee you are likely to encounter is the compulsory angling license  if you plan on fishing in any of the lakes; 35 Kr/day, 100 Kr/week or 140 Kr/year.
Gribskovbanen (The Grib forest railway) is one of the oldest private railways in the country. It was build between 1880 and 1924, mainly to haul lumber between Grib Forest and Copenhagen, which was a tedious venture to do over land, but it has also carried passengers nearly since its beginnings. Today it mainly carries commuters to Hillerød where passengers can continue with the S-train to and from Copenhagen, but during the summer its also packed with vacationers going to their holiday homes or the beaches on the North Coast, or on small treks in Gribskov (Stops: Gribsø, Kagerup & Mårum).
While the royal connotations in the parks name mainly refers to the 3 grand royal palaces of Northern Zealand; Kronborg in Elsinore, Fredensborg Slot in Fredensborg and Frederiksborg Slot in Hillerød, these are actually located inside the respective cities, and are as such not part of the national park itself - although they are perfectly feasible to visit as part of an excursion to the park. There are however, also a number of ruins related to the royal history of the lands contained in the park, that relates to the kings of old, though you'd probably need an interest in archeology or history to go out of your way to see these sites.

Erected as a monastery by Absalon, the founder of Copenhagen, in the 11th century for the Carthusian Order, it was since converted to a palace, taken over by the king, and abandoned after a fire.
