Types of playgrounds

Inclusive playgrounds
Universally designed playgrounds are created to be accessible to all children. There are three primary components to a higher level of inclusive play: physical accessibility; age and developmental appropriateness; and sensory-stimulating activity.Some children with disabilities or developmental differences do not interact with playgrounds in the same way as typical children. A playground designed without considering these children's needs may not be accessible or interesting to them.
Most efforts at inclusive playgrounds have been aimed at accommodating wheelchair users. For example, rubber paths and ramps replace sand pits and steps, and some features are placed at ground level. Efforts to accommodate children on the autism spectrum, who may find playgrounds overstimulating or who may have difficulty interacting with other children, have been less common.

Natural playgrounds

"Natural playgrounds" are play environments that blend natural materials, features, and indigenous vegetation with creative landforms to create purposely complex interplays of natural, environmental objects in ways that challenge and fascinate children and teach them about the wonders and intricacies of the natural world while they play within it.
Play components may include earth shapes (sculptures), environmental art, indigenous vegetation (trees, shrubs, grasses, flowers, lichens, mosses), boulders or other rock structures, dirt and sand, natural fences (stone, willow, wooden), textured pathways, and natural water features.
