Set in the historic Gisselfeld Klosters Forest in Denmark, Camp Adventure features a 900-meter elevated boardwalk zigzagging in and out between the trees, culminating in a 45-meter tower with a 650 meter long inner spiraling ramp, which offers breath-taking panoramic views of the surrounding landscape and nature. The idea behind the elevated boardwalk leading to the tower is to make the forest accessible to everyone without disrupting the natural environment – at habitat to a wide variety of species living in harmony with nature. To achieve this, the tower was constructed by Danish architecture studio EFFEKT from weathered steel and locally sourced oak, to blend in subtly with the surrounding natural context.

The spiraling ramp to the observation deck also benefits from the hyperbolic shape. While keeping a fixed gradient, the geometry and spacing of the ramp fluctuate according to the changing curvature. The ramp becomes a sculptural element that makes the journey to the top a unique experience of shifting intimacy while offering step-free access to all visitors.

“Nature provides the real experience,” explained Tue Foged, one of the two founders of Copenhagen-based EFFEKT. “We just made it more accessible and offered a series of new and alternate perspectives.”

Camp Adventure’s Tower will offer a unique nature experience, not found anywhere else in Scandinavia. The tower’s top platform is 140 meters above sea level and the highest accessible point in the whole of Zealand. In clear weather, there is an unobstructed view 50 km to Copenhagen and Malmo in the north and the rugged Southern Zealand manor landscape to the south and east.

“The tower is shaped to enhance the experience of the visitor, shunning the typical cylindrical shape in favour of a curved profile with a slender waist and enlarged base and crown,” said Foged. “This allows for better contact to the forest canopy moving up through the tower.”
