Dyrehavsbakken (lit. 'Animal Park Hill'), commonly referred to as Bakken (lit. 'The Hill', to distinguish it from Dyrehaven, a royal deer park with public access) is an amusement park in Lyngby-Taarbæk, Denmark, near Klampenborg and approximately 10 km (6 mi) north of central Copenhagen. It is located in the southern part of Dyrehaven, around 600 metres (0.4 mi) away from a public transport connection to the center of Copenhagen (Klampenborg S-train Station). It opened in 1583 (1583) and is the world's oldest operating amusement park. With 2.5–2.9 million visitors per year, it is the second most popular attraction in Denmark, after the more widely known Tivoli Gardens amusement park. Access to the area is free, and admissions are purchased separately for the individual attractions, unlike Tivoli.
