A play tunnel structure (11) providing passageways through which children can crawl and play. The tunnel structure (11) has loops (12) supporting a covering (14) thereby forming a tunnel passageway. The loops (12) comprise discrete rings, (16) and (18), disposed between helical members (20) and (22). When extended, the helical members, (20) and (22), form straight sections of tunnel passage way and the discrete rings, (16) and (18), may form bends in the tunnel passageway. Each discrete ring, (16) and (18), has eyes, (40) and (42), disposed to line up with each other on the outer circumference thereof. A tie (32) is threaded through the eyes, (40) and (42), and pulled taut to gather adjacent rings to thereby form and secure a bend in the passageway of the tunnel structure (11).
