Indoor Series

When weather conditions prevent the use of an outdoor challenge course facility, many programs turn to their indoor courses. Our indoor challenge course designs consist of a prefabricated "superstructure" that serves as the overhead support system - offering ideal positioning of both events and event decks/platforms. From these airy decks, participants can initiate individual and partnered challenge course elements, moving horizontally from one event to the next. The steel framing system and construction techniques produce an easily managed, user friendly and low maintenance challenge course structure.

Based on ATI’s “Multi-Flow” design, the course minimizes participant bottlenecks. Initiatives can be selected from a variety of over 20 events. While not usually as high as outdoor courses, participants will experience a unique perspective that typically heightens the overall challenge. What might appear to be a moderate height from the ground level, will undoubtedly transform into an intensifying and attention demanding position from high in the course!
