Being the major entertainment element of the revitalized city park Na Příkopech in Aš, West Bohemia, the 3D maze consists of little houses at several height levels above the ground connected by suspension bridges. Net-secured rope courses present challenging movement activities for visitors of all ages. Explore the aerial chasms, cave and tunnel right in the middle of Aš city park! The two-storeyed 3D maze forms a 143 meters long aerial trail winding in the trees and park paths. There is both a circular and go-through route connecting 17 transfer houses and 17 rope elements. At the end of this exciting adventure trail, there’s a spiral toboggan. Finally, a picnic meadow, barbecue areas with seating, a gazebo, a pétanque field and minimalist park furniture complete the fresh new look of this city park.

The 3D maze has a complex floor plan with the maximum height of 12 m. The length of suspension bridges is 6.5 to 13 m. Wooden pillars anchored via steel L-consoles to concrete foots form the base of the construction frame. Reinforcement with wooden timber is used on some of the pillars. Barrel-shaped steel houses coated with wooden slats are installed on the columns. Between the houses, there are suspension bridges with side and bottom fall-protection polypropylene (PP) net systems, predominant footbridge floor material being larch planks. The houses on pillars are at two height levels, linked by bridges with rope courses. There are ladders in so-called “drop-in houses”, connecting all the levels of the 3D maze. Attraction entrance and exit are in steel spiral staircases covered with wooden slats, both having lockable gates. Alternate exit is by stainless steel toboggan leading from the top floor. Materials used in action and rope elements are mostly wood, PP ropes with steel core, PP nets, aluminum and plastic links or other special components.
