Known for its large deer population, this massive park north of Copenhagen is a tranquil combination of oak trees and open spaces. A former hunting estate of Danish kings, Dyrehaven is also home to Eremitage Palace, a stately building on a hill originally intentioned for hosting parties, while it also hosts Dyrehavsbakken (Bakken for short), the oldest working amusement park in the world, which has been updated to include a handful of roller coasters, circus performances, cabaret, and other carnival style amenities. Oh yeah, and beer gardens. Entrance is free, although games and rides cost money.
Note:Dyrehavsbakken is only open during the summer months.
