When do the leaves change in Denmark?

Denmark's second-largest forest, 8,000 hectares of beech and heath in Himmerland south of Aalborg. The gnarled, wind-bent beeches of Troldeskoven ("Trolls' Forest") are over 300 years old and turn deep copper through October, while the heather hills of neighboring Rebild Bakker redden alongside them.

North Zealand's largest beech forest at 5,600 hectares, bordering Lake Esrum and part of the UNESCO-listed Par force hunting landscape. Spruce plantations planted in the 1800s are being cleared to restore old beechwood, and the trails out of Nødebo village fill with copper leaf-litter through October.

Denmark's second national park, 180 square kilometers of moraine hills up to 137 meters near Ebeltoft on the Djursland peninsula. Old oak and beech in pockets like Tolløkke Wood turn through October above heath and pasture, with the ruined 14th-century Kalø Castle standing on its own tidal islet at the edge.

An 11-square-kilometer royal hunting park north of Copenhagen, fenced by King Frederik III in 1669 and grazed today by some 2,100 red, fallow, and sika deer. Ancient oaks, a few reputedly over 1,000 years old, turn gold and rust through October around the Baroque lodge Eremitageslottet, timed with the rut.
