Kongernes Nordsjælland National Park

Erected as a monastery by Absalon, the founder of Copenhagen, in the 11th century for the Carthusian Order, it was converted to a palace, taken over by the king, and abandoned after a fire. Archaeological excavations have since exposed the foundations and remaining parts of the walls, and the old moat also remains. Nearby is another excavation of an abandoned village and a number of Tumulus inside the forest

A castle ruin. Built by King Valdemar II (1170-1241) for his wife Dagmar in the 12th century. It was passed on to Seignory, and eventually to decay. Many of building materials were used to reconstruct a local mill after a fire, and so only the foundations remains, but there are nice views over the lake.

May be the most impressive of the parks ruins, its origins are hazy, but it gained prominence under King Valdemar IV (Valdemar Atterdag), who also expanded the castle significantly in 14th century. According the legend he became so attached to it that he "would give up his place in heaven to keep it", something not lost on various Danish poets throughout the ages. The only visible part remaining is the bast of the main tower, which still rises up to 3 meters above the foundations.

An important locality from the Viking age and up to its days as a royal castle from the 12th to the mid-16th century when it was disbanded following the Count's Feud civil war. Many of the stones were used during the construction of Kronborg castle in Helsingør. The moat and ground layout of the old castle is still visible

A 9-km canal between Esrum Sø lake and the north coast at Dronningmølle, built in 1805 to transport timber from the forests to Copenhagen. The canal lost its importance when the railway was built, and was subsequently abandoned. However, it is still visible in the landscape, and while partly overgrown, parts still carry water and many of the old installations related to the canal is still there. The trail where horses used to haul the prams along the canal, still exists, and offers a fantastic walk.

A historic 65-meter hill-top in the middle of the forest, which towers (well, at least for Denmark) above the surrounding area's and offers some nice views over Northern Zealand. The site was home of the massive fruebjergmødere gatherings at the turn of the 19th century, closely related to Grundtvigs folk high school movement. A tradition that has been revived.

A special area of Tisvilde Hegn where 100–200-year-old weather-worn Scots pines with twisted and crooked branches create a peculiar atmosphere, which has prompted locals to dub the area the - enchanted or troll - forest. The phenomenon is caused by strong winds and poor soil conditions.
