Contrary to popular belief, rocks are safe on a playground, and children absolutely love them! And you cannot beat a rock for play value!
Children quickly develop a healthy respect for the solidity and hardness of rocks, and then develop their own sense of care, concern, and safety when they climb on them (a perfect example of children teaching themselves!).
More and more insurance companies and licensing and playground safety inspectors are beginning to appreciate that rocks are really safe and that they are a necessary natural feature that children should learn to understand and respect.
Mastering a Rock Scramble is an accomplishment that children can achieve over and over again and never be bored! The rocks can be easily blended into hills so they become unique and attractive features on any playground.
The hill also becomes a place for tunnels, caves, waterfalls, balance tiers, forts, and many other exciting natural play features.
Teachers love hills as well, because from the top, they can supervise and see everything! Note: this picture shows a rock scrambling wall we built into a 10 foot high, constructed hill in the Northeast, but as this "style" boulder is not found in all parts of the country, colors, shapes, and textures of rocks and small boulders may vary dramatically depending on where we can locate them.
For younger children in elementary schools and child care centers, obviously hills are not as tall, and scrambles are smaller. For toddlers, hills vary between 3 and 4 feet tall, with scrambles between 3 and 4 feet wide (~15 rocks needed). For preschoolers, hills vary between 4 and 5 feet tall, with scrambles between 4 and 5 feet wide (~20 rocks needed). For elementary schools, hills vary between 8 and 10 feet tall, with scrambles 6 and 8 feet wide (~35 rocks needed). Rock sizes vary with the age of the children using them, but typical kid-friendly rocks for younger children are 8-10 inches high, 12-15 inches wide/deep, and 12-15 inches long (They are overall bigger for older children).
We're glad to work with you to find exactly what you need for your project.
