The Arc Tunnel is a three-dimensional wobbly climbing structure with stand-out rounded steel posts to hold the net. The spacious surface of the Arc Tunnel offers hours of play for many children and adults alike with its vertical and horizontal climbing. The structure is a great place for sitting, standing or lying which allows everyone to play together. The play ropes with rubber discs provide a place for groups to socialise while gently swaying on the ropes and the transparency makes social play possible throughout the net. While climbing up, around and through the Arc Tunnel, children's physical skills (balance, muscle strength and cross coordination) are challenged.
