Mountain is not just an ordinary slide. It is play equipment combined with the essence of a large mountain, and its form stimulates children's imagination. Going up the uneven steps is like climbing a mountain, the approach to the top is like crossing an arched bridge, going down the spiral slide changes the view rapidly, and the cave is the best place to hide or take a rest. These features make children want to use this slide again and again, and each time they slide down, they can discover something new.
