The Thermopolis play system is a towering mountain of fun, perfect for any children above the age of four. It has an impressive set of rock climbing walls which includes a Craggy Climber Turn Section, a Craggy Climber End Section, and a Vertical PE Rock Climbing Wall. All of these climbing walls are located close to each other so that children can climb across them from one to the next. There is a 4-foot Pod Climber in this area as well, which can assist them in their climb.

There are two slides on this structure as well. The 60-inch Straight Slide provides a fast and intense ride for older children, while the smaller 4-foot Right Turn Slide acts as a gentler alternative for younger children. Thermopolis is covered in smaller attractions as well, including a Ship's Wheel, Rain Wheel, and Single Drum.
