The Spark Series 4-foot Rock Hole Climber is a plastic climber that allows children to imagine that they are crossing a rugged landscape as they climb up to the upper areas of your custom play structure. The steps simulate the craggy surfaces of real rocks, but have flat surfaces which allow children to easily step and balance on top of them. The steps do not have to be subtle, natural colors like real rocks, however. When ordering this product, you have the option to get it in a variety of exciting colors, such as the one shown in the image on this page. The hole at the bottom offers another way to get past this obstacle: children can crawl through it to get to the other side. The durable plastic materials used in this climber make it incredibly sturdy and resilient to weather damage, even after years of play.
