By the numbers: Camp Adventure, Denmark - SilverKris

"Located in Gisselfeld Klosters forest about an hour from Copenhagen, this treetop attraction is dominated by a 45 m, hourglass-shaped observation tower whose top platform stretches around 100 m and whose uppermost viewing deck sits at 140 m above sea level (roughly 25 m above the treetops), offering panoramas that reach Copenhagen, southern Zealand and even Sweden. The site features Denmark’s most extensive zipline at 475 m and ten adventure courses—rope bridges, rock climbing and more—while the accessible route from reception to the viewing platform is a 1.55 km, step-free walk that follows a 900 m treetop boardwalk and a 650 m spiralling ramp; exploring the whole tower typically takes around two hours. Practical touches include dog-friendly access on a leash, and the overall experience emphasizes high, sweeping views combined with active, family-friendly outdoor challenges." - Mia Chenyze
