Nature and countryside Hillerød is surrounded by some of the most extensive woodlands in Denmark, with Store Dyrehave to the south and the forests of Gribskov to the north. Gribskov is the fourth largest connected woodland in the country and both of the forests are rich with wild game, primarily deer. Just east of Gribskov is Esrum Sø, the second largest lake in Denmark and a few kilometers northeast of Hillerøds city center is Fredensborg Palace and its extensive baroque gardens, on the east coast of Lake Esrum. Scattered around the vicinity of Hillerød, is a number of smaller settlements and villages like Tulstrup, Ullerød, Gadevang, Nødebo, Sørup and Ny Hammersholt. Ullerød is both an old parish and a new borough at 150 ha and is connected directly to Hillerød.
