Northern Zealand's attractive beaches stretch along the coastline like pearls on a necklace, broken by such attractive landmarks as the high cliffs at Tisvilde, where you can see all the way across to Sweden. This region is also home to some of Denmark's most attractive woodlands and open spaces like Heatherhill, a protected natural area characterised - as its name suggests - by heather-clad hills. Located near the coast between Tisvildeleje and Asserbo Plantation, the enchanting Troldeskov (Troll Forest) is renowned for its distinctive crooked pine trees, many of which are up to 180 years old. This area is also home to Arresø Lake, Denmark's largest, which boasts a rich bird and animal life. Visitors can take a trip on the ship "Frederikke" which regularly plies the lake and offers a closer glimpse of its unique natural features.
