Passage Adventure Tube 2.0

4' (1,2m) long, straight horizontal passageway. Available in both deck-to-deck (of equal height) and ground-level options. Bumps and grooves inside the tubes make it seem like they’re exploring real caves as they crawl and squiggle their way through. Includes large sidewall windows that allow increased visibility for supervision. In addition, irregular interior surfaces discourage loitering.
