Mental exercises and games of various levels invite big and little tinkerers and thinkers to the Chnobleweg. Here they can construct a floating roof, build a pyramid from two wooden blocks, build a tripod in the air, or turn a wind wheel into a cube. The 3-km trail is suitable for families. On the easy part of the trail, a grill station invites you to stay awhile. The solutions to the riddles are available at stores and restaurants in Hemberg.
