The Mauna Loa playset is an amazing obstacle course of activities for kids to complete. Children will strive to complete each activity in the outer shape of the activity. These include numerous Playshells and Playpods for children to step and leap across, a triple set of Curved Overhead Ladders to help build upper body strength, and a set of Curved Vertical Nets for sideways climbing that uses both arms and legs. There is a shortcut through the middle of the course to make it easier for kids to move at their own pace or catch up with their friends.
